Energy Efficient Routing Scheme for Wireless Sensor Networks

In recent years, Wireless Sensor Networks (closely deployed nodes) are widely used in applications ranging from weather forecasting to defense. It comprises of data gathering nodes (source), transmitting nodes (routers) and data collecting node. Wide research sprang in this area for improving the efficiency of these networks in terms of packet delivery ratio, throughput and reliability by modifying the conventional routing protocols. Also as the nodes come with limited battery major emphasis is also given to develop energy efficient algorithms. In this paper, an energy efficient adaptive routing protocol is developed for improving the Packet Delivery Ratio and decreasing the packet drop and delay. The proposed technique used RSSI, unused energy and congestion degree for choosing the router. PDR has increased by 0.178% and delay has decreased by 4.1ms.
