An optimized routing approach in wireless sensor networks

Wireless Sensor Networks consists of multi detection stations called sensor nodes, which are small, less weight and portable. They are spatially dispersed for monitoring the environmental conditions and to coordinate the activities systematically. Energy limitation is the fundamental drawback in network lifetime. Here, we propose two routing approaches for transmission of data packets in wireless sensor networks. The data packets are routed either through the established route with the help of relay nodes which act as an intermediate nodes or routed through high energy based clusters to reach the destination. Our work includes fault node recovery mechanisms under both the scenarios. The results obtained with the help of NS-2 simulation software concludes that High energy clusters based routing approach outperforms Relay nodes based routing by taking delivery rate, delay and overhead as parameter metrics into consideration.
