Abstract

This paper presents PC-CORP (Power Control based 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 radio model, we combine the region-based routing, rendezvous scheme, sleep discipline and cooperative communication to model data forwarding by cross layer design in WSN. At the same time, a lightweight transmission power control algorithm PCAIMD is introduced to utilize the cooperation of relay nodes to improve the forwarding efficiency performance and increase robustness of routing protocol. In simulation, the performance of PC-COPR is investigated from perspectives of adaptation of variations in network connectivity and satisfying QoS requirements of application.
