MULTI-HOP DISTRIBUTED ENERGY EFFICIENT HIERARCHICAL CLUSTERING SCHEME FOR HETEROGENEOUS WIRELESS SENSOR NETWORKS

Abstract

Wireless sensor network (WSNs) are network of Sensor Nodes (SNs) with inherent sensing, processing and communicating abilities. One of current concerns in wireless sensor networks is developing a stable clustered heterogeneous protocol prolonging the network lifetime with minimum consumption of battery power. In the recent times, many routing protocols have been proposed increasing the network lifetime, stability in short proposing a reliable and robust routing protocol. In this paper we study the impact of hierarchical clustered network with sensor nodes of two-level heterogeneity. The main approach in this research is to develop an enhanced multi-hop DEEC routing protocol unlike DEEC. Simulation results show the proposed protocol is better than DEEC in terms of FDN (First Dead Node), energy consumption and Packet transmission.
