ETSP: An Energy-Efficient Time Synchronization Protocol for Wireless Sensor Networks
Wireless Sensor Networks (WSN) have specific constraints and stringent requirements in contrast to traditional wired and wireless computer networks. Among these specific requirements, energy-efficiency is the most prominent. Sensor motes have finite amount of energy supply. In most WSN applications, hundreds or thousands of motes are deployed in an area (e.g., behind enemy lines or foliage) and there is no provision for battery recharging. Therefore, a fundamental constraint on WSN applications and services is to extend the network’s lifetime by making the batteries run longer. In this paper we propose an energy-efficient Time Synchronization Protocol, referred as ETSP, which gives significant improvement in energy consumption over existing time synchronization schemes. We first evaluate the existing Reference Broadcast Synchronization (RBS) and Timesync Protocol for Sensor Networks (TPSN), which are two prominent examples of receiver-receiver and sender-receiver synchronization met...
