Abstract :
This paper presents CORP (cooperative opportunistic routing protocol) for WSN (Wireless Sensor Networks), providing robustness to the random variations in network connectivity while ensuring better data´s forwarding efficiency in an energy efficient manner. Based on Realistic link layer, we combine the region-based routing, rendezvous scheme, sleep discipline and cooperative communication to model the data´s forwarding by cross layer design in WSN. Simulation results show that COPR performs better than Non-cooperative opportunistic routing from perspectives of adaptation of variations in network connectivity and satisfying application QoS requirements.
