Abstract A major application level task in wireless sensor network operation is the formation of an adaptive local network, and the sensing data from sensors are gathered at a central node for various cooperative signal processing functions. Based on mutual information theory, the overhead different central node election scheme is analyzed, and demonstrate diffusing computing election is more overhead efficient. An Adaptive Cooperative Communication Routing Protocol (ACCRP) is proposed: nodes select central node and construct route in distributed manner. The proof of correctness about ACCRP is presented. The performance of ACCRP is tested by simulation. The simulation results indicate that ACCRP is energy efficient, scalable and adaptive.
