Design and Performance Analysis of Energy Efficient Routing Algorithm for Wireless Sensor Network

Wireless Sensor Networks (WSNs) are communication networks, which integrate sensor techniques, embedded techniques and distributed information processing techniques. One of the issues in smart sensor networks is achieving energy efficient operation because of the limited available power. In many biomedical applications, the locations of sensor nodes are fixed and the placement can be predetermined. In this paper, the Directional Source Aware Protocol (DSAP) is described along with the principle and a new Energy Efficient DSAP is proposed to minimize the usage of available energy or power in sensor nodes. A few extra bits are transmitted in the header to inform all the neighbors about next immediate receiver, which is the future source for the next transmission. Energy efficiency is achieved by keeping the neighbors of transmitting node in sleep mode and the intended receiver on.In this work different routes and topologies are considered. The energy consumed by the nodes and the lifetime of the network are analyzed.
