• Recommendation system based on space-time user similarity
  by Wei Luo, Zhihao Peng, Ansheng Deng 
  Abstract: With the advent of 5G, the way people get information and the means of information transmission have become more and more important. As the main platform of information transmission, social media not only brings convenience to people's lives, but also generates huge amounts of redundant information because of the speed of information updating. In order to meet the personalised needs of users and enable users to find interesting information in a large volume of data, recommendation systems emerged as the times require. Recommendation systems, as an important tool to help users to filter internet information, play an extremely important role in both academia and industry. The traditional recommendation system assumes that all users are independent. In this paper, in order to improve the prediction accuracy, a recommendation system based on space-time user similarity is proposed. The experimental results on Sina Weibo dataset show that, compared with the traditional collaborative filtering recommendation system based on user similarity, the proposed method has better performance in precision, recall and F-measure evaluation value.
  Keywords: time-based user similarity; space-based user similarity; recommendation system; user preference; collaborative filtering.
  
  
• Design and analysis of novel hybrid load-balancing algorithm for cloud data centres  
  by Ajay Dubey, Vimal Mishra 
  Abstract: In recent the pandemic scenario there is a paradigm shift, from traditional computing to internet-based computing. Now is the time to store and compute the data in the cloud environment. The Cloud Service Providers (CSPs) establish and maintain a huge shared pool of computing resources that provide scalable and on-demand services around the clock without geographical restrictions. The cloud customers are able to access the services and pay according to the accession of resources. When millions of users across the globe connect to the cloud for their storage and computational needs, there might be issues such as delay in services. This problem is associated with load balancing in cloud computing. Hence, there is a need to develop effective load-balancing algorithms. The Novel Hybrid Load Balancing (NHLB) algorithm proposed in this paper manages the load of the virtual machine in the data centre. This paper is focused on certain problems such as optimisation of performance, maximum throughput, minimisation of makespan, and efficient resource use in load balancing. The NHLB algorithm is more efficient than conventional load-balancing algorithms with reduced completion time (makespan) and response time. This algorithm equally distributes the tasks among the virtual machines on the basis of the current state of the virtual machines and the task time required. The paper compares the result of proposed NHLB algorithm with dynamic load-balancing algorithm and honeybee algorithm. The result shows that the proposed algorithm is better than the dynamic and honeybee algorithms.

• Cloud infrastructure planning considering the impact of maintenance and self-healing routines over cost and dependability attributes  
  by Carlos Melo, Jean Araujo, Jamilson Dantas, Paulo Pereira, Felipe Oliveira, Paulo Maciel 
  Abstract: Cloud computing is the main trend regarding internet service provision. This paradigm, which emerged from distributed computing, gains more adherents every day. For those who provide or aim at providing a service or a private infrastructure, much has to be done, costs related to acquisition and implementation are common, and an alternative to reduce expenses is to outsource maintenance of resources. Outsourcing tends to be a better choice for those who provide small infrastructures than to pay some employees monthly to keep the service life cycle. This paper evaluates infrastructure reliability and the impact of outsourced maintenance over the availability of private infrastructures. Our baseline environments focus on blockchain as a service; however, by modelling both service and maintenance routines, this study can be applied to most cloud services. The maintenance routines evaluated by this paper encompass a set of service level agreements and some particularities related to reactive, preventive, and self-healing methods. The goal is to point out which one has the best cost-benefit for those with small infrastructures, but that still plans to provide services over the internet. Preventive and self-healing repair routines provided a better cost-benefit solution than traditional reactive maintenance routines, but this scenario may change according to the number of available resources that the service provider has.

• Data collection in underwater wireless sensor networks: performance evaluation of FBR and epidemic routing protocols for node density and area shape  
  by Elis Kulla 
  Abstract: Data collection in Underwater Wireless Sensor Networks (UWSN) is not a trivial problem, because of unpredictable delays and unstable links between underwater devices. Moreover, when nodes are mobile, continuous connectivity is not guaranteed. Therefore, data collection in UWSN Node scarcity and movement patterns create different environments for data collection in underwater communication. In this paper, we investigate the impact of the area shape and node density in UWSN, by comparing Focused Beam Routing (FBR) and Epidemic Routing (ER) protocols. Furthermore, we also analyse the correlation between different performance metrics. From simulation results we found that when using FBR, delay and delivery probability slightly decrease (2.1%) but the overhead ratio decreases noticeably (46.9%). The correlation between performance metrics is stronger for square area shape, and is not noticeable for deep area shape.

• Joint end-to-end recognition deep network and data augmentation for industrial mould number recognition  
  by RuiMing Li, ChaoJun Dong, JiaCong Chen, YiKui Zhai 
  Abstract: With the booming manufacturing industry, the significance of mould management is increasing. At present, manual management is gradually eliminated owing to need for a large amount of labour, while the effect of a radiofrequency identification (RFID) system is not ideal, which is limited by the characteristics of the metal, such as rust and erosion. Fortunately, the rise of convolutional neural networks (CNNs) brings down to the solution of mould management from the perspective of images that management by identifying the digital number on the mould. Yet there is no trace of a public database for mould recognition, and there is no special recognition method in this field. To address this problem, this paper first presents a novel data set aiming to support the CNN training. The images in the database are collected in the real scene and finely manually labelled, which can train an effective recognition model and generalise to the actual scenario. Besides, we combined the mainstream text spotter and the data augmentation specifically designed for the real world, and found that it has a considerable effect on mould recognition.

• An SMIM algorithm for reduction of energy consumption of virtual machines in a cluster  
  by Dilawaer Duolikun, Tomoya Enokido, Makoto Takizawa 
  Abstract: Applications can take advantage of virtual computation services independently of heterogeneity and locations of servers by using virtual machines in clusters. Here, a virtual machine on an energy-efficient host server has to be selected to perform an application process. In this paper, we newly propose an SMI (Simple Monotonically Increasing) estimation algorithm to estimate the energy consumption of a server to perform application processes and the total execution time of processes on a server. We also propose an SMIM (SMI Migration) algorithm to make a virtual machine migrate from a host server to a guest server to reduce the total energy consumption of the servers by estimating the energy consumption in the SMI algorithm. In the evaluation, we show the energy consumption of servers in a cluster can be reduced in the SMIM algorithm compared with other algorithms.

• FIAC: fine-grained access control mechanism for cloud-based IoT framework  
  by Bhagwat Prasad Chaudhury, Kasturi Dhal, Srikant Patnaik, Ajit Kumar Nayak 
  Abstract: Cloud computing technology provides various computing resources on demand to the user on pay per use basis. The users use the services without the need for establishment and maintenance costs. The technology fails in terms of its usage owing to confidentiality and privacy issues. Access control mechanisms are the tools to prevent unauthorised access to remotely stored data. CipherText Policy Attribute-based Encryption (CPABE) is a widely used tool for facilitating authorised users to access the remotely stored encrypted data with fine-grained access control. In the proposed model FIAC (Fine-Grained Access Control Mechanism for cloud-based IoT Framework ), the access control mechanism is embedded in the cloud-based application to measure and generate a report on the air quality in a city. The major contribution of this work is the design of three algorithms all of which are attribute based: key generation algorithm, encryption and decryption algorithms. Only authorised users can view it to take appropriate action plans. Carbon dioxide concentrations, dust, temperature, and relative humidity are the parameters that we have considered for air quality. To enhance the security of the cloud-based monitoring system, we have embedded a security scheme, all of which are attribute based. Further, the computation time of the model is found to be encouraging so that it can be used in low power devices. The experimental outcomes establish the usability of our model.

• University ranking approach with bibliometrics and augmented social perception data  
  by Kittayaporn Chantaranimi, Rattasit Sukhahuta, Juggapong Natwichai 
  Abstract: Typically, universities aim to achieve a high position in ranking systems for their reputation. However, self-evaluating rankings could be costly because the indicators are not only from bibliometrics, but also the results of over a thousand surveys. In this paper, we propose a novel approach to estimate university rankings based on traditional data, i.e., bibliometrics, and non-traditional data, i.e., Altmetric Attention Score, and Sustainable Development Goals indicators. Our approach estimates subject-areas rankings in Arts & Humanities, Engineering & Technology, Life Sciences & Medicine, Natural Sciences, and Social Sciences & Management. Then, by using Spearman rank-order correlation and overlapping rate, our results are evaluated by comparing with the QS subject ranking. From the result, our approach, particularly the top-10 ranking, performed estimating effectively and then could assist stakeholders in estimating the university's position when the survey is not available.

• Strongly correlated high utility item-sets recommendation in e-commerce applications using EGUI-tree over data stream  
  by P. Amaranatha Reddy, M. H. M. Krishna Prasad, S. Rao Chintalapudi 
  Abstract: The product recommendation feature helps the customers to select the right items in e-commerce applications. Grounded on a similar kind of customer purchase history previously, it recommends the items to the customers. The customers may or may not choose from the recommended items list. Suppose the customers like and purchase them, it is added advantage to both the buyers and the sellers. In sellers' sales, they get the benefit of an increase; in addition, the buyers too can save their time to search. Thus, a recommendation system must be designed so that the suggested items have High Utility (HU) and strong correlation to meet such requirements. High profit is exhibited by the HU items and the strongly correlated items have more probability of selection. As these measurements have significant roles in the business process, both of those measurements of items needed to be taken care. Here, since up-to-date data in the data stream are got, the stream of purchase transactions is mined using the sliding window technique to extract such item-sets.
  Keywords: high utility item-set mining; recommendation system; utility; correlation; data stream; sliding window.

• Hybrid optimisation-based reliable routing with traffic management and congestion control  
  by Kaveri Kori, Sridevi Hosmani 
  Abstract: Reliable routing with traffic management in VANET is the most critical aspect that to be solved on an emergency basis. There is a need for a trust computing system adapted to the peculiarities of VANETs to deal with the significant factors of road safety. The purpose of this work is to suggest a new improved trust-based methodology for dependable transmission. To transmit the data packet efficiently, the cluster head selection and optimal routing process takes place. The Fuzzy C-Means Clustering (FCM) technique is employed to select the cluster head, in which the node with high energy is elected as the cluster head. Followed by, a novel hybrid optimization named the Beluga whale-assisted Coati Optimization (BwACO) algorithm is proposed, which is the combination of the Beluga Whale Optimization (BWO) and Coati Optimization Algorithm (COA). The greatest mobility offered using the BWACO approach is -146.386 at the median statistical metric.

  by Xiaoxuan Xu, Yuanyou Cui, Dianhua Tang, Yunfei Cao, Jindan Zhang 
  Abstract: With the continuous development and improvement of cloud computing and big data technology, the cloud audit has gradually become more and more important. For the huge data storage, how to carry out data integrity auditing in the edge environment is very critical. This paper studies and explores the data integrity auditing scheme based on certificateless public key cryptography in the edge environment, analyze the security flaws of the original scheme in the signature generation process, and improves it. The security analysis shows that the new scheme can effectively resist the original attack and three types of adversary in certificateless cryptography, and the computational overhead is reduced in the auditing phase. Finally we discuss its application in COVID-19 epidemic data management.

• Assessment of six router replacement methods for router placement optimisation in WMNs considering different network scales and subway mesh client distribution  
  by Admir Barolli  
  Abstract: In this paper, we present the implementation of a hybrid intelligent simulation system called WMN-PSOHCDGA by integrating Particle Swarm Optimization (PSO), Hill Climbing (HC) and Distributed Genetic Algorithm (DGA). We consider Subway distribution of mesh clients and carry out simulations for six router replacement methods (CM, RIWM, LDIWM, LDVM, RDVM and FC-RDVM) and different scales of Wireless Mesh Networks (WMNs). For evaluation, we consider three metrics: network connectivity, coverage of mesh clients and load balancing. The simulation results show that all six router replacement methods have good network connectivity for both small and middle scale WMNs. For small scale WMNs, the mesh clients coverage and load balancing are almost the same. However, for middle scale WMNs, CM and FC-RDVM perform better than other router replacement methods.

• An intelligent mechanism for requirements change management of cloud computing requests  
  by Nassima Bouchareb 
  Abstract: Cloud environments are typically highly dynamic, making it challenging to identify, clarify, and manage their requirements, especially when services and requirements change unpredictably. In this work, we introduce an agent-based mechanism designed to manage requirements changes, with a specific focus on requests for virtual machines (VM) allocation/reallocation in a Cloud Computing system. We begin by explaining the principle of the virtual machine allocation mechanism and the roles of the various agents involved. Next, we present the steps of the requirements change management process. Additionally, we delve into the various cases of requirements changes caused, whether initiated by the Cloud provider or customers, including adding a request, canceling a request, and modifying a request. Finally, we provide a case study and simulation results demonstrating that our proposed mechanism increases the number of accepted requests, enhances tasks processing, and minimize energy consumption, ultimately boosting the profit of Cloud providers.

• A systematic review of eye-tracking data in NLP: exploring low-cost and cross-lingual possibilities  
  by Alba Haveriku, Hakik Paci, Nelda Kote, Paola Shasivari, Elinda Kajo-Mece 
  Abstract: Integrating eye-tracking data into text processing models is consistently demonstrating improvements in their outcomes. Numerous studies have been undertaken to explore low-cost alternatives and investigate cross-lingual possibilities. In our systematic literature review, we provide an overview of the related studies, based on four main dimensions: eye-tracking in natural language processing (NLP) subfields, cross-lingual eye-tracking, most relevant eye-tracking devices, and low-cost eye-tracking opportunities. We highlight key studies showcasing that integrating eye-tracking data during training or testing improves the accuracy of NLP models in diverse subfields. There is a necessity to analyse eye-tracking data across different languages to explore cross-lingual patterns and variations. Furthermore, eye-tracking devices vary in form, sampling rate, accuracy, and costs. Notably, low-cost devices are demonstrating acceptable accuracy rates, paving the way for a potentially cost-effective future in conducting eye-tracking experiments.

• A fuzzy-based system for assessment of emotional trust: a comparison study of two implemented models  
  by Shunya Higashi, Phudit Ampririt, Ermioni Qafzezi, Makoto Ikeda, Keita Matsuo, Leonard Barolli 
  Abstract: In recent years, the human-to-human and human-to-things relationships are become increasingly complicated and unreliable, which makes difficult the decision in different applications and situations. As a result, trust computing is gaining interest in a number of research fields. The emotional trust is one of the trust concept. In this paper, we implemented a system called Fuzzy-based System for Assessment of Emotional Trust (FSAET). We implement two models: FSAETM1 and FSAETM2. The FSAETM1 considers three input parameters: Expectation (Ex), Willingness (Wi), Attitude (At) and the output parameter is Emotional Trust (ET). In FSAETM2, we consider Propensity (Pr) as a new parameter. The simulation results show that the FSAETM2 is more complex than FSAETM1 but performs better ET since four parameters are considered.

• Assessment of a cuckoo search-based intelligent system for mesh routers placement optimisation in WMNs considering various distributions of mesh clients  
  by Shinji Sakamoto 
  Abstract: Wireless Mesh Networks (WMNs) have many advantages. However, they have several issues related to wireless communication. An effective approach to deal with these problems is the optimization of mesh routers placement in WMNs, but this is an NP-hard problem. Thus, heuristic and intelligent algorithms are needed. In the previous work, we developed an intelligent simulation system based on Cuckoo Search (CS) (WMN-CS), which is a meta-heuristic algorithm. In this work, we evaluate the WMN-CS performance for various distributions of mesh clients: Uniform, Normal, Exponential, Weibull and Chi-square distributions. The simulation results show that for Normal distribution the WMN-CS system can find suitable locations of mesh routers for about 30 phases. The Uniform distribution has the lowest performance compared to the other distributions. Also, Exponential andWeibull distributions converge slower than Chi-square distribution. However, Exponential distribution converges faster than Weibull distribution.

• Experimental evaluation of downlink communication performance of IEEE 802.11ax wireless LAN: OFDM vs. OFDMA  
  by Tatsuya Oogami, Hitomi Tamura, Daiki Nobayashi, Kazuya Tsukamoto 
  Abstract: Although Orthogonal Frequency Division Multiple Access (OFDMA), adopted in IEEE 802.11ax, allows an Access Point (AP) to simultaneously communicate with multiple stations (STAs), the bandwidth of the Resource Unit allocated to each STA is inversely proportional to the number of STAs. In contrast, Orthogonal Frequency Division Multiplexing (OFDM) allows an AP/STA pair, determined by carrier-sense multiple access with collision avoidance, to dominate the entire bandwidth. However, the latency before packet transmission increases with the number of STAs. The number of STAs that want to communicate with an AP thus significantly impacts on throughput under both OFDM and OFDMA. Therefore, this study evaluates the communication performance for rich content and voice data when multiple STAs are connected to an AP. Through experiments, we identify suitable environments, in terms of the number of STAs and traffic type, for OFDM and OFDMA to improve the Quality of Experience (QoE) and throughput.

• Fuzzy forests for feature selection in high-dimensional survey data: an application to the 2020 US Presidential Election  
  by Sreemanti Dey, R. Michael Alvarez 
  Abstract: An increasingly common methodological issue in the field of social science is high-dimensional and highly correlated datasets that are unamenable to the traditional deductive framework of study. Analysis of candidate choice in the 2020 Presidential Election is one area in which this issue presents itself: in order to test the many theories explaining the outcome of the election, it is necessary to use data such as the 2020 Cooperative Election Study Common Content, with hundreds of highly correlated features. We present the fuzzy forests algorithm, a variant of the popular random forests ensemble method, as an efficient way to reduce the feature space in such cases with minimal bias, while also maintaining predictive performance on par with common algorithms such as random forests and logit. Using fuzzy forests, we isolate the top correlates of candidate choice and find that partisan polarisation was the strongest factor driving the 2020 Presidential Election.

• An efficient intrusion detection system using unsupervised learning AutoEncoder  
  by N.D. Patel, B.M. Mehtre, Rajeev Wankar 
  Abstract: As attacks on the network environment are rapidly becoming more sophisticated and intelligent in recent years, the limitations of the existing signature-based intrusion detection system are becoming more evident. For new attacks such as Advanced Persistent Threat (APT), the signature pattern has a problem of poor generalisation performance. Research on intrusion detection systems based on machine learning is being actively conducted to solve this problem. However, the attack sample is collected less than the normal sample in the actual network environment, so it suffers a class imbalance problem. When a supervised learning-based anomaly detection model is trained with these data, the results are biased toward normal samples. In this paper, AutoEncoder (AE) is used to perform single-class anomaly detection to solve this imbalance problem. The experimental evaluation was conducted using the CIC-IDS2017 dataset, and the performance of the proposed method was compared with supervised models to evaluate the performance

• Optimal attack detection using an enhanced machine learning algorithm  
  by Reddy Saisindhutheja, Gopal K. Shyam, Shanthi Makka 
  Abstract: As computer network and internet technologies advance, the importance of network security is widely acknowledged. Network security continues to be a substantial challenge within the cyberspace network. The Software-as-a-Service (SaaS) layer describes cloud applications where users can connect using web protocols such as hypertext transfer protocol over transport Layer Security. Worms, SPAM, Denial-of-service (DoS) attacks or botnets occur frequently in the networks. In this light, this research intends to introduce a new security platform for SaaS framework, which comprises two major phases: 1) optimal feature selection and (2) classification. Initially, the optimal features are selected from the dataset. Each dataset includes additional features, which further leads to complexity. A novel algorithm named Accelerator updated Rider Optimisation Algorithm (AR-ROA), a modified form of ROA and Deep Belief Network (DBN) based attack detection system is proposed. The optimal features that are selected from AR-ROA are subjected to DBN classification process, in which the presence of attacks is determined. The proposed work is compared against other existing models using a benchmark dataset, and improved results are obtained. The proposed model outperforms other traditional models, in aspects of accuracy (95.3%), specificity (98%), sensitivity (86%), precision (92%), negative predictive value (97%), F1-score (86%), false positive ratio (2%), false negative ratio (10%), false detection ratio (10%), and Matthews correlation coefficient (0.82%).

• Enhanced speculative approach for big data processing using BM-LOA algorithm in cloud environment  
  by Hetal A. Joshiara, Chirag S. Thaker, Sanjay M. Shah, Darshan B. Choksi 
  Abstract: In the event that one of the several tasks is being allocated to an undependable or jam-packed machine, a hugely parallel processing job can be delayed considerably. Hence, the majority of the parallel processing methodologies, namely (MR), have espoused diverse strategies to conquer the issue called the straggler problem. Here, the scheme may speculatively introduce extra copies of a similar task if its development is unnaturally slow when an additional idling resource is present. In the strategies-centred processes, the dead node is exhibited. the (RT) along with backup time of the slow task is assessed. The slow task is rerun with the aid of BM-LOA subsequent to the evaluation. In both heterogeneous and homogeneous environments, the proposed approach is performed. Centred on the performance metrics, the proposed research techniques performance is scrutinised in experimental investigation. Thus, when weighed against the other approaches, the proposed technique achieves superior performance.

• Importance of big data for analysing models in social networks and improving business  
  by Zhenbo Zang, Honglei Zhang, Hongjun Zhu 
  Abstract: The digital revolution is the build-up of many digital advances, such as the network phenomena transformation. To increase business productiveness and performance, participatory websites that allow active user involvement and the intellectual collection became widely recognized as a value-added tool organization of all sizes. However, it has lacked an emphasis on business and management literature to promote profitable business-to-business (b2b). User knowledge is a way to consider the kinds of search ions that big data can use. The use of social media data for analysing business networks is a promising field of research. Technological advances have made the storage and analysis of large volumes of data commercially feasible. Big information represents many sources of organised, half-structured, and unstructured data in real-time. Big data is a recent phenomenon in the computing field, which involves technological or market study. The management and research of a vast network provide all companies with significant advantages and challenges. The volume of information floating on social networks grows every day and, if processed correctly, provides a rich pool of evidence.

• Study on the economic consequences of enterprise financial sharing model  
  by Yu Yang, Zecheng Yin 
  Abstract: Using enterprise system ideas to examine the business process requirements of firms, the Financial Enterprise Model (FEM) is a demanding program. This major integrates finance, accounting, and other critical business processes. Conventional financial face difficulties due to low economic inclusion, restricted access to capital, lack of data, poor R&D expenditures, underdeveloped distribution channels, and so on. This paper mentions making, consuming, and redistributing goods through collaborative platform networks.
