Distance Based Enhanced Threshold Sensitive Stable Election Routing Protocol for Heterogeneous Wireless Sensor Network

Abstract

Translate Article

The technological advancements have led to the revolution in sensing technology. Wireless Sensor Network (WSN) has been one of the important researched areas which have attracted attention of various researchers. The battery constraints have led to the development of energy efficient routing protocols. Past studies ignore the importance of distance factor for the selection of Cluster Head (CH), which led to inefficient energy consumption in the network. In this chapter, Distance based Enhance Threshold Sensitive Stable Election Protocol (DETSSEP) has been proposed in which CH selection is based on networks average energy, nodes remaining energy and distance between nodes and Base Station (BS). Dual hop communication is used between distant CHs and BS to achieve uniform energy consumption in the network. It is observed through the simulation analysis that DETSSEP outperforms Enhance Threshold Sensitive Stable Election Protocol (ETSSEP) in various performance matrices viz. stability period, throughput, lifetime and remaining energy of the network.
