Performance Analysis Based on Battery Power Condition Over Wireless Sensor Network

Abstract

Wireless sensor network(WSN) is an emerging technology that has been popularized by its wide range of potential applications including military surveillance, habitat monitoring, object tracking, traffic monitoring, etc. The area that cannot be accessed easily are monitored by WSNs. The major problem or challenge of WSN is the life time of network or node due to depletion of battery energy. In many application of wireless sensor network there may be the need for the packets to be transmitted as soon as possible in such cases the slight delay can make large differences. Here, energy based routing protocol called Battery Condition Ad hoc on Demand Distance Vector (BCAODV) has used to improve the system performance of the WSN. The concept of priority of packet has been also used to handle the sensitive or delay tolerant packet. The system performance has been analyzed on the basis of packet delivery ratio, throughput and end to end delay. The packet delivery ratio and throughput has been found to be batter in case of the BCAODV than AODV protocol. However the end to end delay is better in the later one protocol. The time taken by the sensitive packet to reach its intended destination has improved when using priority. The algorithm development and simulation are carried out in Network Simulator (NS2).
