Analysis of Network Lifetime for Wireless Sensor Network

Wireless Sensor Network (WSN) consists of motes which are equipped with limited battery and requires energy management for enhanced Network Lifetime. In this paper we have adopted a deployment strategy which is performed over a region of interest (ROI) obtained from contour integration of one hop to other. The selection of motes depending on the type of application is also analyzed. The necessity of proper resource utilization in a sensor network enables us to propose a realistic radio model which considers the sorted power level from discrete radio model. The utility of Network coding is also adapted for enhanced throughput and robustness of the network.
