Energy efficient layered cluster based hierarchical routing protocol with Dual Sink

Abstract

In recent days lifetime of Wireless Sensor Network (WSN) is an important issue to consider. The lifetime of a WSN depends on the energy consumption of sensor nodes. In this paper a new hierarchical routing protocol Layer Based Low-Energy Adaptive Clustering Hierarchy (LB-LEACH) is proposed to increase the lifetime of WSN in which layer factor is considered as a cluster head selection parameter to improve the performance of cluster head selection algorithm proposed in LEACH, EECHS and energy aware LEACH. We also use the concept of Dual Sink i.e. a static sink and multiple mobile sinks to increase the efficiency of data collection. Simulation result shows that our proposed algorithm LB-LEACH performs better than LEACH, Energy aware LEACH and EECHS.
