PERFORMANCE EVALUATION OF THRESHOLD SENSITIVE STABLE ELECTION REACTIVE PROTOCOL IN WIRELESS SENSOR NETWORK

Abstract

Wireless sensor network refers to the collection of hundreds to thousands of geographically dispersed and distributed sensor node, where each node is connected to one or more sensors, for monitoring and recording conditions of environment at diverse locations and organizing the collected data at a central location. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance. Today wireless sensor networks are used in many industrial and consumer applications, such as industrial process control and monitoring, machine health monitoring, and so on. Commonly monitored parameters are temperature, pressure, wind direction and speed, vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels and vital body functions. Reactive networks as opposed to proactive networks responds immediately to the changes in required parameters of interest, due to continuous sensing nature of WSN. The efficiency and improvement in terms of energy in network’s lifetime is one of the crucial issues in wireless sensor networks (WSNs) [36, 37]. WSNs are expected also to finds the wide applications and increasing deployments in near future. In this paper, we proposed an efficient version of TSEP Protocol, which prolongs the networks lifetime as we have simulated. We evaluated the performance of our protocol and compared the results with the TSEP. And from the results of simulation, it is observed that our protocol perform better in terms of lifetime.
