Abstract
This paper presents a channel aware contention based forwarding scheme (CACF) for wireless sensor network(WSN). In order to improve the probability of correct packet transmission in wireless channel and ensuring successful contention, CACF selects the appropriate relay node by the integrated consideration of access probability, routing cost metrics and wireless channel characteristics. In the scheme, a well-defined access space mechanism (ASM) is proposed and used as criterion for relay selection during each contention round. The simulation results show that CACF achieves better network performance in terms of packet delivery ratio and improves the node efficiency consequently.
