Energy efficient time synchronization protocol for wireless sensor networks

Abstract

In last few years, the Wireless Sensor Network (WSN) have been an important research area because its use has been tremendously increased in different fields such as military, environment, medical, home monitoring and disaster management etc. In such applications, time synchronization is an important problem. To identifying the correct event time, these nodes need to be synchronized with the global time. The energy conservation is one of the important issues in WSNs which helps to prolong the lifetime of the network. In this paper, we present a energy efficient Time Synchronization algorithm in which each layer of the WSN can be synchronized with base station simply by multicasting the synchronization messages The simulation results shows that this algorithm reduce the energy consumption as compare to RBS and TPSN. © 2011 Springer-Verlag.
