Performance Analysis of Energy Dissipation in WSNs Using Multi-Chain PEGASIS

Abstract — In wireless sensor networks, sensor nodes have limitation of energy so the lifetime of the networks is very important design factor.There are proposed many routing protocols for the wireless sensor networks recently. One of these protocols, the PEGASIS (Power-Efficient GAthering in Sensor Information Systems) protocol is a chain-based routing scheme that are proposed for reducing energy consumption of communication in the networks. In general, the PEGASIS protocol give twice or more performance in comparison with the LEACH (Low Energy Adaptive Clustering Hierarchy) protocol. The chain-based routing schemes construct the chains for routing path. The chain-based routing schemes use the concept of multi-hop routing. The proposed approach divides the single chain into multiple parts. It decreases the network overhead due to fewer numbers of nodes in chains. Minimization of data delivery delay is also an important requirement to improve network performance. In the proposed method nodes are divided in several regions and different chains are made for each region, it reduces the delay between nodes to BS, hence energy load is distributed uniformly among the chains. Overall performance analysis is measured in terms of network lifetime in terms of Sum of Remaining Energy (Joule) with number of rounds. We compare the LEACH, PEGASIS and proposed method with respect to 15J, 20J, 25J and 30J Energy, Where initial energy level of nodes are 0.5J. Proposed method is found to be 20% better at performance than PEGASIS and 72 % than LEACH
