Item Advances in Communication, Signal Processing, VLSI, and Embedded Systems: Select Proceedings of VSPICE 2019(Springer, Singapore, 2020) Kallya, Shubhakar; Kulkarni, Muralidhar; Shivaprakasha, K.S.This book comprises selected peer-reviewed papers from the International Conference on VLSI, Signal Processing, Power Systems, Illumination and Lighting Control, Communication and Embedded Systems (VSPICE-2019). The contents are divided into five broad topics - VLSI and embedded systems, signal processing, power systems, illumination and control, and communication and networking. The book focuses on the latest innovations, trends, and challenges encountered in the different areas of electronics and communication, and electrical engineering. It also offers potential solutions and provides an insight into various emerging areas such as image fusion, bio-sensors, and underwater sensor networks. This book can prove to be useful for academics and professionals interested in the various sub-fields of electronics and communication engineering.Item Information Theory and Coding(Wiley, New Delhi, 2018) Kulkarni, Muralidhar; Shivaprakasha, K.S.Item Performance analysis of energy efficient modulation and coding schemes for wireless sensor networks(2013) Shivaprakasha, K.S.; Kulkarni, M.; Patkar, R.Sensor nodes of a typical wireless sensor network (WSN) are battery driven, so energy conservation is a critical factor for node's life time. Thus optimisation of energy consumption is a major objective in the area of WSNs. One such method is asymmetric communication which uses different channel codes and modulation schemes for downlink (base station (BS) to node link) and uplink (node to BS link). In this paper, a performance analysis of different channel code-modulation pair for energy efficient asymmetric communication is carried out followed by the field programmable gate array implementation of channel codes required at the node. The per information bit node energy for the uplink has been calculated for efficient channel code-modulation pair, for three different channels, viz. additive white gaussian noise, Rayleigh flat-fading and log-normal shadowing channels, resulting in reduction in energy consumption at sensor nodes. 2013 Copyright Taylor and Francis Group, LLC.Item Range adjustable hybrid multi path routing algorithm for WSNs(2017) Nishant, J.D.; Kulkarni, M.; Shivaprakasha, K.S.Node disjoint multipath routing is an effectiveway to achieve reliability and load balancing in wireless sensor networks (WSNs). In this paper, an attempt has been made in proposing a novel node disjoint multipath routing algorithm, the range adjustable hybrid multipath (RAHM). RAHM uses hybrid routing approach. The centralised node disjoint path selection is based on the objective of minimising the end to end communication drain on each path. The localised distributed route reconfiguration initiates on the node failure events and the route re-establishment is based on the objective of residual energy of the nodes. The performance of the proposed algorithm is validated through simulations and compared with collection tree protocol (CTP) and multipath ring routing protocol. RAHM performs around 36% and 76% better in terms of network lifetime parameter compared to CTP and multipath ring routing protocol respectively. 2017 Inderscience Enterprises Ltd.Item Improved network survivability using multi-threshold adaptive range clustering (M-TRAC) algorithm for energy balancing in wireless sensor networks(2013) Shivaprakasha, K.S.; Kulkarni, M.; Joshi, N.Wireless Sensor Networks (WSNs) have become one of the most prominent areas of research in the field of modern communication systems. But unlike IP based routing, WSNs focus on data centric communication. Thus routing is one of the important issues to be considered for a WSN. As sensor networks are generally deployed in hostile environments, batteries cannot be recharged often. Thus energy conservation is one of the important design parameters for WSNs. Many energy aware routing protocols were proposed in the literature. Cluster based algorithms were proved to be better compared to multi-hop routing. In this paper an attempt is made in proposing a novel cluster based energy efficient routing algorithm for WSNs namely the Multi-Threshold Adaptive Range Clustering (M-TRAC) algorithm, which incorporates centralized network management with variable thresholds in order to assure a uniform load distribution amongst nodes, thus improving the network lifetime. 2013 - IOS Press and the authors.

They find their applications in various fields like habitat monitoring, home automation, environment monitoring, battle field environment etc. WSNs are different from Mobile Adhoc Networks in the perspective of energy awareness, adaptive communication patterns and the routing algorithms. As the sensor devices are powered by batteries, which cannot be recharged often, the power awareness is one of the major requirements in WSNs. Many energy aware routing protocols have been proposed in the literature. In this survey, an attempt has been made to summarize the various energy aware routing protocols available in the literature and also a comparative analysis of these has been made considering various network parameters like the delay, routing overhead, QoS, type of routing protocol etc. 2011 Praise Worthy Prize S.r.l. - All rights reserved.Item Energy efficient shortest path routing protocol for wireless sensor networks(2011) Shivaprakasha, K.S.; Kulkarni, M.Wireless Sensor Networks (WSNs) have become one of the emerging trends of the modern communication systems. Routing plays a vital role in the design of a WSNs as normal IP based routing will not suffice. Design issues for a routing protocol involve various key parameters like energy awareness, security, QoS requirement etc. Energy awareness is one of the vital parameters, as the batteries used in sensor nodes cannot be recharged often. Many energy aware protocols were proposed in the literature. In this paper, we propose a new Energy Efficient Shortest Path (EESP) algorithm for WSNs, which manages uniform load distribution amongst the paths so as to improve the network performance as compared to the traditional shortest path routing strategy. � 2011 IEEE.
