Performance Analysis of Energy Conservation Techniques for Wireless Sensor Networks

In this paper, the problem of energy management in Wireless Sensor Network (WSN) for data collecting, computing and transfer is investigated. Battery powered sensors need efficient management due to limited energy resources, and energy conservation is a vital design issue that needs to be boosted in order to increase the lifespan of a network. Therefore, the important aspect of WSN design is resistant, secure and efficient communication relevant to radio devices with limited energy resources. Algorithms for dynamic transmission power control, clustering, activity control of devices and power save routing protocols are briefly summarized. The results of the performance evaluation of selected solutions through simulation and experiments conducted in testbed networks are presented and discussed.
