摘要: 无线传感器网络的重要应用特性是具有感测信息的传感节点形成一个自适应本地网络，由中心节点执行不同的协作信息处理任务。该文基于互信息量分析了不同中心节点选择机制的开销性能，证明了基于扩散计算的选择机制的开销有效性；提出一种自适应协同通信路由协议(ACCRP)：节点以分布式的方式选择中心节点并建立传输路径；分析讨论了ACCRP的性能参数；并通过实验验证了ACCRP是能源有效的、可扩展的自适应路由协议。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.
