  • A novel weighted relaying algorithm for opportunistic mobile sensing system applications
    Mehul B. Shah
    Proceedings of the Confluence 2020 10th International Conference on Cloud Computing Data Science and Engineering, 2020
    Novel mobile information systems are being developed with the use of smartphones. The traditional applications of wireless sensor networks such as environmental monitoring, health care, and transportation are being realized by many mobile social network applications. Smartphones forward various onboard sensor data using a store-carry-forward way to the central repositories over the internet. In this paper, inter contact time distribution of each smartphone user with other users is utilized for efficient sensor data routing. A novel threshold-based approach is used to estimate future interconnection times. Human mobility based Weighted Relaying Algorithm (Hm-WRA) is proposed for routing in opportunistic mobile sensing systems. The proposed protocol performs almost 15% to 20% better compared to an intercontact time based shortest path routing algorithm named CHARON in terms of the data delivery ratio with proper selection of threshold value at each node.
  • Performance Evaluation of Moving Sink based Pollution Data Collection for Different Sink Movements in Wireless Sensor Network
    Mehul B. Shah, Anish Vahora
    Proceedings of the 3rd International Conference on Electronics and Communication and Aerospace Technology Iceca 2019, 2019
    Pollution data needs to be collected in urban areas for monitoring purposes. Among various approaches moving sink/ data mule based approach is more effective from energy consumption perspective. In this approach mobile sink gathers information from the static sensors of the network and transfer it to uploading server or base station. The Sink Trail protocol is one such protocol which handles this task in an efficient way. The logical coordinate system of Sink Trail protocol ease routing and forwarding without using GPS.The impact of different moving patterns of sink can affect the performance of packet received and energy consumption. In this paper various sink movements such as straight line, linear and zigzag pattern at constant speed is considered for protocol evaluation. The size of the network is also varied for different movements. The simulation results demonstrate substantial differences for different sink movements.
  • Efficient data gathering in wireless sensor network using mobile sink
    Rathod Yogirajsinh, Mehul B. Shah, Parthesh Mankodi
    2016 IEEE International Conference on Recent Trends in Electronics Information and Communication Technology Rteict 2016 Proceedings, 2017
    In wireless sensor networks data gathering is very important task. Nowadays analysis has been targeted on decreasing the energy consumption of the WSN. To solve this drawback the conception of movable sink is presented. In this approach mobile sink gather the inform the static sensors of the network and transfer it to base station. For efficiently gather the data sink's mobility pattern should be decided so the data collection time will be reduced. Sink Trail (ST) and Sink Trail-S (STS) protocols are used to find shortest path for data forwarding through the nodes to sink. Constant updating of unnecessary sink location needs to be reduced. Therefore STS protocol is proposed to overcome the difficulty of ST protocol. The logical coordinate system (LCS) is proposed for the ease of routing and forwarding and because of it any location prediction strategy or GPS not required. This protocol enhances the energy efficiency. We analyze the impact of broadcasting frequency on route length and energy consumption. The simulation result of ST with data aggregation demonstrates that the proposed method reduces the amount of network traffic which helps to reduce energy consumption.

  • A node scheduling approach in community based routing in social Delay Tolerant Networks
    Nikhil Gondaliya, Mehul Shah, Dhaval Kathiriya
    2015 International Conference on Advances in Computing Communications and Informatics Icacci 2015, 2015
    Delay Tolerant Networks (DTNs) also provide the communication to the group of people who carries the mobile devices like smart phone, laptop and palmtop. By exploiting the human characteristics it becomes easy to pretend the social properties which are useful in selecting the appropriate relay node. Many routing protocols have shown the capability of these properties (eg. community and centrality) and improved the performance in terms of delivery ratio and delivery delay. The performance of community based routing protocols mainly depends on the formation of the correct community structure. The admission criteria to add the node in the local community is based on aggregated contact duration or contact frequency between node pair. Until it exceeds the predefined threshold value, node cannot be added in to the local community of each other. Even it is difficult to predict the value of threshold in advance for any data set. By analyzing a community structure at different times, it is found that a community detection similarity is very low in early phase of the simulation. Within the entire network, some nodes are more popular and interact with more nodes than others called hub or central nodes. These nodes play important role in improving the delivery ratio. Hence, we propose the simple approach to schedule the nodes for message transmission based on the two centrality measures: betweenness and degree in the absence of the community information about message's destination. We validate our proposed scheme using real time traces of two different environments: conference and campus and compared with existing scheme. The simulation results show the higher delivery ratio and low average hop count value for the traces of both the environments.
  • Performance evaluation of efficient routing protocols in delay tolerant network under different human mobility models
    Namita Mehta, Mehul Shah
    International Journal of Grid and Distributed Computing, 2015
    Delay and/or Disruption-Tolerant Networking (DTN) is a novel communication prototype that can span across multiple networks and deal with unpredicted conditions in the Internet model.Delay-tolerant networks (DTNs) are partitioned wireless ad hoc networks with intermittent connectivity. Additional terminology in this family of dynamic networks includes disruption-tolerant networks, intermittently connected networks, and opportunistic networks. Routing of the packets in DTN is based on store-carry-and forward paradigm. In this paper, we study and analyze performance of well known PROPHET and Spray and Wait routing protocol, under different human mobility models such as Truncated Levy Walk mobility model (TLW),Self-similar Least Action Walk (SLAW) and Random way point (RWP) model. The MATLAB simulator is used in order to analyze the performance of these routing protocols.Simulation results illustrate that Spray and Wait significantly outperforms the PROPHET on aspects of delivery ratio, average delay and communication overhead.
  • A dynamic opportunistic spectrum access MAC protocol for Cognitive Radio networks
    Smit B Tripathi, Mehul B Shah
    Proceedings of the 2014 International Conference on Advances in Computing Communications and Informatics Icacci 2014, 2014
    Cognitive radio can be regarded as the intelligent wireless devices which can sense the medium and effectively utilize the vacant or underutilized spectrum. The cognitive radio enables the Secondary Users (SU) to opportunistically access the spectrum unused by the Primary Users (PU). There are two basic objectives of Cognitive Radio Medium Access Control (CR MAC): controlling interference and avoiding PUs and avoiding collision between SUs. We propose a MAC protocol for single channel which opportunistically utilizes the spectrum unused by the PUs. It has a licensed channel in the primary network. The time in the network is divided in terms of slot time. Slot time is of equal length and packet transmission in carried out in slots. It is partitioned in two phases which are the contention phase and the data transmission phase. The first phase selects a SU based on 802.11 DCF with RTS/CTS mechanism. The second phase is for data transmission. The SU is allowed to occupy all the time remaining after the contention phase. In case of collision, a dynamic backoff scheme is applied. We compare the results of the OSA MAC for single channel with dynamic MAC scheme. The results show that throughput of proposed scheme is better than the conventional OSA scheme.
  • Spectrum sensing in wideband OFDM based Cognitive Radio
    Pratik R Parekh, Mehul B Shah
    International Conference on Communication and Signal Processing Iccsp 2014 Proceedings, 2014
    Cognitive Radio is a novel technology in today's radio environment to improve the utilization efficiency of radio spectrum. In this paper we are going to use Orthogonal Frequency Division Multiplexing (OFDM) based spectrum sensing cognitive radio system is addressed. The main purpose is to identify the underutilized spectrum or white space without inferring the PU signal, called Existing Users (EUs) system altogether. To use the unused spectrum, spectrum sensing is needed to know whether the PU is present or not. The performance of cooperation based spectrum sensing scheme will be studied for OFDM based cognitive user using the energy detector method and wavelet based spectrum sensing scheme. Several factors like fading and shadowing affects the ability of cognitive radio to detect the PU. Here AWGN as well as Rayleigh fading channel are considered. Wavelet edge detection is one of the most widely used spectrum sensing techniques. This technique observes a spatial distribution of spectral data at multiple resolutions. The slope of the power spectral density is used as an index to differentiate between sharp and blurred peaks. Power spectra with conspicuous peaks utilize Haar wavelet transform, while for subtle peaks use Gaussian wavelet transform, and also explain how wavelet transform is advantageous then Energy detection.
  • Efficient scheduling algorithm for query processing in Opportunistic Sensor Network under human mobility model
    Mehul B. Shah, Jignesh L. Rathod
    Proceedings of the 5th International Conference on Confluence 2014 the Next Generation Information Technology Summit, 2014
    In an Opportunistic Sensor Network (OSN), mobile nodes equipped with sensor are tasked by Sensor Access Points (SAPs) in aid of applications running distantly on the Internet. Mobile sensor nodes upload sensed data back to the SAP once its tasked queries are sensed. In an OSN, node mobility is uncontrolled and the performance of scheduling algorithms relies on opportunistic meeting between human-attached sensors and SAPs. In this paper we are proposing and evaluating the performance of a novel Human Mobility based Shortest Job First (HMB-SJF) Scheduling algorithm for efficient query processing under the human mobility models such as Truncated Levy Walk (TLW). HMB-SJF performs better compared to naïve instantaneous mobility based MB-SJF scheduling algorithm. Number of uploading of sensed queries are improved by almost 15% for HMB-SJF compared to MB-SJF.
