Cross Layer Integrated MAC and Routing Protocol Based on Ring Based Structure with Adaptive Sleeping for Wireless Sensor Networks

Cross-Layer Design have now developing hottest research area in wireless sensor systems as it is pursuing to improve the ability of wireless networks remarkably through the joint optimization of several layers in the network. The design of our protocol is to deal with the overhearing problem and low duty cycle based on adaptive sleeping. The Mac layer is using the information of routing layer to decide the node duty cycle in order to extend the node's sleep time. Thus cross layer protocol design objective is to reduce protocol overhead significantly for route discovery as ring based structure find shortest path for the node in the outer ring to the sink in the network. Extensive simulation results shows that ring based protocol EEIMRP as compared to IMRP can significantly reduce the protocol overhead thus reduces delay in the network, improves energy efficiency, throughput and prolonged network lifetime.
