Improving the Lifetime of Wireless Sensor Networks Based on Routing Power Factors

Abstract

In this paper the power efficiency of Wireless Sensor Networks (WSNs) Power is studied. Power consumption is the main challenge during the routing of data. The objective of this study is to address three routing parameters that affect the network life time such as initial power of the nodes, the residual power in the nodes and routing period. Simulations of the effects of these parameters are presented in different network sizes. Contribution on how to improve network lifetime through consideration of power consumption factors during routing is added. © Springer-Verlag Berlin Heidelberg 2012.
