Energy Efficient Event Tracking in Wireless Sensor Networks

Abstract

Advances in the wireless communications and the microelectronic technologies have been expediting the development of wireless sensor networks. Deploying a high number of sensors to increase the redundancy of the system can help increase the lifetime of the network. It is very important to reduce the energy consumption of wireless sensor networks in such high density networks. In this paper, hexagonal based deployment is used as a network topology to reduce the energy consumption by activating set of sensor nodes which cover the whole monitor area and remaining nodes kept in sleep node to save energy. We develop NS (Network Simulator) simulator to demonstrate the performance of the proposed algorithm. And also this algorithm implemented in event tracking applications of wireless sensor networks. For that, NS is extended to support the wireless sensor networks simulation.
