  • Smart Healthcare Model with Fog-Cloud Network Architecture   Order a copy of this article
    by Rohan Basu Roy, Arani Roy, Amitava Mukherjee, Mrinal Kanti Naskar 
    Abstract: In this paper, the performance of an Internet of Things (IoT) based, real time, smart ECG signal compression and transmission protocol is investigated through both simulation and hardware implementation. The protocol consists of a combination of Fog and Cloud computing architecture. The input to the model is noisy ECG signal acquired through sensors. The model is based upon a four layered structurernwith first layer consisting of wearable ECG sensor and noise filter embedded in the device. Second layer is an encoder which consists of an algorithm subdivided into two schemes namely, Geometry Based Method (GBM) and Wavelet Based Iterative Thresholding (WTIT). The algorithm is based on the fact that ECG signals can be approximated by the linear combination of a few coefficients obtained from a wavelet basis. GBM reduces the minimal signal values to zero geometrically in time domain and WTIT encodes the signal in time-frequency domain. Further, Compressed Row Hoffman Coding algorithm (CRHFC) is applied to convert the sparse coefficient matrices to compressed, transmittable matrices. The third layer consists of wireless transmission medium from the wearable to a private Cloud, from where data is accessed by the hospital servers. The data obtained in the receiver is the final layer where signal reconstruction is performed using inverse transforms. The performance metrics-compression ratio (CR), percentage RMS differencern(PRD), Quality Score (QS), time complexity and sparsity are used to evaluate the performance of the model.

    by DIPANWITA GANGULY, Saborni Das, Abhik Hazra, Ashish Laddha, Mousumi Basu 
    Abstract: Real coded genetic algorithm (RCGA) and improved real coded genetic algorithm (IRCGA) have been applied for the solution of short-term hydrothermal scheduling problem. The improved technique has been developed and tested on a multi reservoir cascaded hydroelectric system having generation-load power balance, upper and lower limits on reservoir capacity, water discharge rate, water spillage rate, hydraulic continuity restriction and operating capacity limits of different hydro and thermal units. The water transport delay between connected reservoirs has also been taken into consideration. The performance of the proposed approach is validated with four test systems. The results of the proposed algorithm are compared with those of modified differential evolution (MDE), teaching learning based optimization (TLBO), clonal selection algorithm (CSA), improved fast evolutionary programming (IFEP), improved particle swarm optimization (IPSO), and genetic algorithm (GA). From numerical results, it has been found that the IRCGA based approach is able to provide better solutions in lesser computational time.

  • A New Energy-Preserving Cloud Offloading Algorithm for Smart Mobile Devices   Order a copy of this article
    by Samar A. Said, Sameh A. Salem, Samir G. Sayed 
    Abstract: The advent of mobile devices becomes the way for various technological developments in mobile communication and information technology. However, mobile users expect to access computational intensive applications through resource constrained mobile devices. Consequently the growing demands for boosting the computations, storage and memory resources became essential for mobile devices. A new trend to incorporate mobile devices and cloud resources with the existence of the network connectivity is named as mobile cloud computing (MCC). MCC is the greatest solution to increase the application processing capabilities on mobile devices by migrating the application to the cloud servers with on demand and unlimited resources. This paper proposes a new energy-preserving cloud offloading algorithm. The proposed algorithm estimates the application computational time and uses multiple weighted parameters to give accurate offloading decisions. Simulation results on various applications clarify that the proposed algorithm is capable of estimating an applications computation time with high correlations compared with the real execution time. This improves the offloading decision which actually preserves the energy and reduces the execution time of mobile applications.

  • A Differential Evolution-Based Routing Algorithm for Multi-Path Environment in Mobile Ad-hoc Network   Order a copy of this article
    by Anju Sharma, Madhavi Sinha 
    Abstract: Optimization is a procedure through which the best possible ways of decision variables are obtained under the given set of constraints and in accordance to a selected optimization objective function. Over the last decade, Differential Evolution (DE) algorithms have been extensively used in various problem domains and succeeded effectively in finding the optimal solutions. The DE algorithm is a bio-inspired, heuristic approach with three advantages; finding the true global minimum regardless of the initial parameter values, fast convergence, and using limited control parameters. The present paper emphasis on a DE algorithm based Ad-hoc On-demand Multi-path Distance Vector (DE_AOMDV) protocol for MANET. The proposed DE_AOMDV routing protocol has better performance, effectively extends the working lifetime of the system, and improves the quality of the wireless ad-hoc networks. The main objective of this research paper is to find the optimal path from available multiple paths between source and destination to be used in route recovery process. DE_AOMDV provides backup paths to avoid reroute discovery in the case of link failure between nodes. The descriptive analysis of the comparative study of DE_AOMDV protocol in terms of End to End Delay, Packet Delivery Ratio and Throughput with AOMDV protocol is the primarily focus of this paper. Simulation based results and data analysis shows DE_AOMDV protocol is better than AOMDV.

  • Performance Improvement of Vehicular Ad-Hoc Network with Nature Inspired Biological Computing Algorithm   Order a copy of this article
    by Komal Mehta(Bhagat), Preeti Bajaj, L.G. Malik 
    Abstract: Vehicular Ad-Hoc Network (VANET) is a hybrid Ad-Hoc network between vehicles and Road Side Units (RSUs). It uses various routing techniques to establish thecommunication link between vehicles and RSUs. Although there are many routing techniques available, still finding stable routedue to the high mobility of nodes is an open challenge.However intelligent techniques are used to solve this problem up to some extent, this paper introduces a new routing algorithm to find a stable route. The proposed algorithm is a hybrid algorithm which uses ZoneBased Routing, fuzzy logic, andNature Inspired Biological Computing (NIBC) algorithm. In proposed algorithm ZoneBased Routing is used to divide the network into small and stable zones,fuzzy logic is used to find the quality of links between nodes, and NIBC to find the stable route in short time.Six techniques for the VANET has been implemented and compared in this paper. Among them, five are NIBC techniques including proposed one, and sixth is state of art algorithm AODV. NS2.34 network simulator is used for simulations. Simulations were carried out for variable transmission rate and variable speed. Five performance parameters; packet delivery ratio, packet drop ratio, control overhead, average delay, and throughput have been taken to analyze the results. Simulation results have shown that NIBC algorithms improve the performance of VANET and the proposed algorithm has the best performance among them.

  • Energy Efficient Service Differentiated QoS aware Routing in Cluster Based Wireless Sensor Network   Order a copy of this article
    by Yogita Patil 
    Abstract: In today's technological era, WSNs has gained attention worldwide with its miniature size and low cost. Data transmission demands both energy and quality of service (QoS) to ensure efficient use of the sensors and adequate access to collecting information. Lot of research work in literature has been focused on QoS provisioning by differentiated service technique that differentiates and priorities different traffic classes to meet the user requirements. Our work toward scheduling is based on packet type providing high priority to emergency data to facilitate reliable transmission of emergency data in critical situations. We proposed an approach for effective sensing by use of stochastic scheduling to increase the energy efficiency of sensor nodes for intracluster communication. The proposed technique in this work outperforms when compared with the existing protocol in the literature in terms of minimized energy consumption, delay, and high throughput by offloading of the energy-intensive tasks.
