A Review of Power Optimization Strategies in Wireless Sensor Network

Abstract — The challenging task of wireless sensor network is to increase the lifetime as they are equipped with critical battery power. Once WSN is deployed in disaster areas, inaccessible terrains or polluted environments, battery recharge or replacement is impossible. For optimizing the battery power of the sensor network, various energy efficient routing strategies are applied. This paper reviews the recent energy optimizing routing protocols and their performance. We first outline from basic sensor network model to routing strategy in terms of energy optimization. Our review concludes with the recommendations to the future scope in the energy optimization model for the wireless sensor networks
