A Comparison of Perspectives of Kuwaiti and Indonesian Residents Towards E-Government
by Dinesh A. Mirchandani, Yunus A. Kathawala, Julius H. Johnson Jr, John P. Hayes, Sudhir Chawla
Abstract: Kuwait and Indonesia are two Asian countries with similar literacy rates and median ages of residents. An understanding of their residents' perspectives can help the governments of these countries better plan their e-government services and provide useful information to other countries. The current study used a survey to assess the importance of e-government services and website features from the perspective of Kuwaiti and Indonesian residents. Multigroup analysis was used to validate the instrument and research model. Four relationships were found to correspond across datasets, but only one relationship was found to be significantly different between the two datasets, i.e., the relationship of resident feedback services to the websites savings and control feature was significantly stronger (p < 0.01) in the Indonesian dataset as compared to the Kuwaiti dataset. The multigroup analysis demonstrated that residents in both countries interpreted the survey instrument similarly and had comparable expectations for e-government services and website features.

Performance analysis of a 5G Non-Orthogonal waveform-filter bank Multi-Carrier
by Ravi Sekhar Yarrabothu, Sadhana ,. Kandukuri, Usha Rani Nelakuditi, M. Krishna Chennakesava Rao
Abstract: As the world, is looking for more data speeds along with support for M2M communication in the next generation (5G), the current orthogonal frequency division multiplexing (OFDM) has limitations such as high PAPR, spectrum wastage due to cyclic prefix (CP), out of band (OOB) emissions. To overcome these limitations, 5G researchers is looking for different wave forms and filter bank multi carrier (FBMC) waveform is one of the prime contenders. In this paper, it has been implemented, the poly-phase network filter bank multi carrier (PPN-FBMC), which reduces the high complexity and computations. A prototype filter for the PPN FBMC with high overlapping factors (K = 6 and 8) are implemented. It also simulates FBMC system using Matlab Software, to characterise and analyse the 5G candidate waveform FBMC and compare with OFDM, in terms of error vector magnitude (EVM), peak to average power ratio (PAR), and power spectral density (PSD) performance. The simulated results prove that FBMC outperforms the OFDM systems in all the above mentioned aspects, even under noisy conditions.

Bit error rate performance analysis of Cholesky decomposition based quasi ML receiver for large scale MIMO system
by Kasiselvanathan M, N. Sathish Kumar
Abstract: Large Scale Multiple Input Multiple Output (LS-MIMO) system is an emerging technology that has large antennas at both transmitter and receiver. In this paper, a novel approach is proposed namely Cholesky Decomposition based Quasi Maximum likelihood (ML) detector followed by List Sequential (LISS) decoder (Quasi ML-LISS) receiver for LS-MIMO system. The Refined Empirical Log-Likelihood Ratio (RELLR) generated by ML soft detector is decoded by using LISS decoder. The performance of the receiver is enhanced for turbo coded MIMO system by generating the RELLR at the detector output for higher order modulation. Simulation results show that Bit Error Rate (BER) performance of proposed receiver is closer to the ML performance and superior to the Multiple Stage (MS) receiver.
Keywords: BER; bit error rate; QAM; quadrature amplitude modulation;maximum likelihood; MIMO; multiple input multiple output; signal detection.

by C. Ramesh, K. Venu Gopal Rao, D. Vasumathi
Abstract: The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. The transition from closed networks to enterprise IT networks to the public Internet is accelerating at an alarming pace and justly raising alarms about security. As we become increasingly reliant on intelligent, interconnected devices in every aspect of our lives, how do we protect us from intrusions and interference that could compromise personal privacy. Security is paramount for the safe and reliable operation of IoT connected devices. In this aspect Identity-Based Cryptography(IBC) plays a promising role in Internet of Things (IoT) due to its benefits, such as facilitating public key management. This paper gives a detailed feasibility study of applicability of IBC in IoT.

A Survey on Integrity Verification and Data Auditing Schemes for Data Verification in Remote Cloud Servers
by R. Muthuram, G. Kousalya
Abstract: Cloud computing is the opportunistic model that provides a lot of services to the business organisations to concentrate more on their own business services instead of spending more cost on maintenance. The service providers provide an unlimited storage capability to the clients with characteristics like scalability, reliability, on-demand self-service etc. Clients host their data on cloud servers and pay the cost based on their usage. The data consumers can access the data from the cloud servers. Because of lack of access control and data may tamper by malicious users, business organisations hesitating to use the cloud computing. Ensuring the data storage correctness and integrity is one of the major issues in the cloud computing. In this paper, we discussed the various integrity system models that are available and the procedure for the various existing integrity verification schemes proposed.

by Desabandhu Parasuraman, Sathiyamoorthy Elumalai
Abstract: Nowadays, the real challenge is to manage the dynamic web content in order to provide a prolific resource to the user. Web personalisation is an outcome of the challenge by which the web is a tailor made to a user. Recommendation systems access the user profile using collaborative filtering and content based filtering to provide better personalisation. This paper focuses on improving the accuracy of item recommendations, based on the dynamicitem-based collaborative filtering by utilising time variant system which is implied on user ratings. Similarity between the items is found by using vector similarity and weight is calculated by Pearson correlation coefficient. Comparison of the results of traditional item-based collaborative filtering with dynamic item-based collaborative filtering is also discussed. Finally, it is observed that the users dynamic voting average improves the accuracy of recommendations comparing to the normal voting average on items.
Keywords: recommendation systems (RS); user profiles; collaborative filtering (CF); time variant system; vector similarity.

Tunnel Transistor Based Energy Efficient and Reliable Computing Architectures at Low VDD
by Sadulla Shaik, K. Sri Rama Krishna
Abstract: Tunnel field-effect transistors (TFETs) have emerged as one of the most promising post-CMOS transistor technologies. This paper presents design analysis and benchmarking of TFET based three different 1-bit full adders (8T-XOR Logic, 6T-XOR Logic and MUX Based) are used for designing 4-bit adders in two different topologies targeting a VDD below 500 mV. These topologies are 22T/18T 1-bit full adder based 4-bit carry propagate adder (22T/18TCPA) and multiplexer logic 1-bit full adder based 4-bit carry propagate adder (MCPA). The performance of TFET based 4-bit adder topologies has been benchmarked with 20 nm double gate Si FinFET technology. Tunnel FETs are desirable candidates for building energy efficient and reliable arithmetic blocks with supply voltage scaling. We demonstrate that TFETs steep slope characteristics enable the 22TCPA design to be energy efficient option along with improved reliability and 18TCPA design is the best in terms of energy efficiency and reliability amongst all designs at low supply voltages.

Impact of Deflection History based Priority on Adaptive Deflection Router for Mesh NoCs
by Elizabeth Isaac, M. Rajasekhara Babu
Abstract: Assimilation of several cores insist scalable and scattered communication configuration. On chip supports bus as a medium, but it has multiple cores. Network on Chip (NoC) is proffered over bus. Traditional designs employ input buffered routers which form the backbone of NoC. NoCs with buffer-less routers gain popularity due to its router design, low power and less chip area. The most innovative and inventive step in deflection router is to employ side buffers instead of input port buffers. Here proposea deflection history as a priority metrics for flit selection and modified the primitive DeBAR design, and propose Priority Based Deflection Based Adaptive Router (PBDeBAR) that utilizes a cost effective priority scheme to choose a flit that has to be shifted to side buffer. Experimental outcome shows that PBDeBAR reduces latency, deflection rate, buffer occupancy and link usage with respect to the existing minimally buffered deflection routers.

Shortest Path Establishment Approaches for Static and Dynamic Mobile Nodes with Quality of Service
by S. Sundar, Aritra Basu, Arunava Kar, R. Kumar
Abstract: An ideal routing algorithm is one which finds the best/shortest path(s) for transmitting the data between source and destination in a short time. In this study, we have proposed two approaches; one is based on Minimum Spanning Tree (MST) and the other one is based on Distance Vector Method (DVM).For MST, Genetic Algorithm is used. The chromosomes used are of variable length and their genes are used for encoding. The cross over and mutation operations are used for genetic diversity and improving the convergence rate. The second method is based on DVM to cover the limitations of the first approach as well the traditional DVM. The developed algorithm finds the shortest path for static mesh connected mobile nodes. It is then tested for dynamicity by varying the positions of a few nodes. Extensive simulations are carried out on both the approaches and the results are compared with other popular algorithms.

Efficient Routing Based on Core Relay Intermediate Nodes in MANET
by P. JAYALAKSHMI, R. Saravanan
Abstract: Efficient routing in MANETs is necessary for effective data communication among nodes. Routing can be done either single-hop or multihop. If source and destination are within the transmission range then single-hop routing is established, else multi-hop routing is required to route the data packets to reach the destination. Selection of next hop based on the speed of movement of nodes and transmission range: reduces overall energy consumption, link failures and delay constraints. The weights of the link quality between the nodes present in the network can be estimated by using cost metrics such as distance and travelling speed of the node since the efficient routing is done with better link quality nodes. To minimize the hop counts and to reduce the packet loss in the network, an efficient route should be established between source and destination. The success of the data transmission via Core Relay Intermediate Nodes (CRIN) can be analysed using NS-2 tool. The efficiency of 0.4% is improved by using the proposed scheme. Network performance can be enhanced through shortest path so that messages may be delivered in a timely manner.
