Energy Efficient Optimal Path based coded transmission for multi-sink and multi-hop WSN

Abstract

Multi-hop communication with multiple sinks provides better data propagation in terms of network throughput, bandwidth and energy consumption in energy and computationally constraint wireless sensor network. In this paper, we come up with the conceptualization of network coding scheme based transmission over a pre-defined minimum Wiener index spanning tree (MWST) based multi-hop routing access in a multiple sink scenario for energy constraint wireless sensor network. For effective data transmission between sensor nodes to sink node, we have proposed XOR based network coding i.e. COPE. Contrary to the previous methods in literature, we here deployed random sensor nodes over a pre-defined area. Each sensor node is connected with one and only one sink node depending on its Euclidian distance and number of hops between them and the same is implemented by nature inspired Particle Swarm Optimization (PSO) technique. Finally, the data transmission is enriched with the network coding approach for significant decrease in energy consumption and enhancement in network throughput gain.
