Wireless sensor networks are becoming popular in many industrial and civilian application areas. The need is to improve the performance of such systems that can be significantly done by using adaptive cooperative diversity (SCA) technique, which is basically a cross-layer design that combines truncated ARQ at the link layer and cooperative diversity at the physical layer. In addition to it, LEACH protocol gives advantage of utilizing randomized rotation of local cluster-heads to evenly distribute the energy load among the sensors in the network. This paper proposes an integrated system, SCA with LEACH and evaluates its performance with LEACH with truncated ARQ system. Comparison is done based on network lifetime and packet loss rate of system under varying propagation scenarios, number of retransmissions, initial energy by node and network size. Simulation results show better performances with various achieved thresholds.
