摘　　要：无线传感器网络低功耗MAC地址编码设计需要综合考虑地址通信能量开销、地址编码容量、不同地址类型支持等因素的影响。首先分析了现有定长地址编码和哈夫曼地址编码算法的优缺点,给出了地址编码性能评估参数,接着提出了一种混合地址编码算法,仿真结果表明新算法融合了两种地址编码优点,较好地满足了无线传感器网络低功耗MAC地址编码的设计要求。The design of low power MAC address coding in wireless sensor networks must consider the effect of following factors, such as the energy consumption of address transmission, the capacity of address codes and the support of different address types. The advantages and disadvantages of current methods of fixed size coding and Huffman address coding are analyzed. A mixing address coding is presented and the performance parameters of address coding are put forward. The simulation results show that the new method merges the advantages of two kinds of address coding method and satisfies the design requirements of low power MAC address coding in wireless sensor networks.
