【Abstract】 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.更多还原
