Improved and rule scheme to increase lifetime of wireless sensor networks

Abstract

Wireless sensor network (WSN) is a network of small light weight wireless nodes which are highly distributed and deployed in large numbers. The sensor nodes scan the environment and provide useful information to the user through sink node. One of the major issues in wireless sensor networks is developing an energy-efficient routing technique which has a significant impact on the overall lifetime of the sensor network. Our dissertation work focuses on increasing lifetime of wireless sensor networks. This is done by improving the existing Divide and Rule Scheme which is based on dividing network area into logical divisions to reduce distance for intra cluster and inter cluster communications. Improvement of Divide and Rule Scheme is done by developing a new scheme called Segregated Receive and Relay Scheme in which addition of relay nodes is done in inner and middle regions. The Proposed Scheme results in around 50% increase in lifetime of inner region nodes and leading to overall increase in lifetime of the network. Other parameters such as Delay, Throughput and Packet loss also shows better results in new Scheme.
