摘要: MAC地址只需要局部唯一而无需全局唯一,可对同一MAC地址在不同区域进行空间复用。在GAF算法形成的特殊的虚拟单元格拓扑结构中,可以对簇头节点和簇内节点采取不同的MAC地址复用策略。分析簇头节点和簇内节点MAC地址空间复用的限制条件及复用方法,在此基础上提出一种分布式的MAC地址空间复用算法。理论分析和模拟实验表明,该算法能有效减少MAC地址长度、节约网络能耗,在密集网络中能保持良好的性能。

Abstract: In sensor network, MAC address requires to be unique partially rather than globally, so MAC address can be reused in different regions. In the special virtual grid topology formed by GAF algorithm, different MAC address allocation strategies can be adopted for clusters and nodes. The restrictions of the distribution of MAC address for clusters and nodes are discussed separately, a distributed algorithm for spatial reuse of MAC address is proposed. Theoretical analysis and simulation experiments show that the algorithm can effectively reduce the length of MAC address and energy consumption, and can keep good performance in intensive network.

Key words: Wireless Sensor Network(WSN), virtual grid, MAC address, spatial reuse
