Abstract: Aiming at reducing energy consumption caused by node address in Wireless Sensor Network(WSN), a dynamic address assignment and updating algorithm is developed. The MAC address is designed to consist of cluster address and inner-cluster address, where the cluster address is obtained from its corresponding address reuse area which is generated through node clustering and cluster merging, and the inner-cluster address is assigned with different lengths. Furthermore, a utility-function-based scheme is proposed for inner-cluster address updating where the utility function is designed to consider both current and past energy consumption status of a node. Simulation results show that the proposed algorithm can efficiently decrease the average address length, avoid address conflictions, and reduce the energy consumption caused by node address effectively.

摘要: 为降低无线传感器网络中传输节点地址所导致的能量消耗,提出一种动态MAC地址分配与更新算法。节点MAC地址由簇地址和簇内地址构成,通过簇合并构成簇地址复用区域以获得簇地址,为簇内各节点分配不等长的簇内地址。提出一种基于效用函数的地址更新策略,综合考虑各节点当前和历史耗能情况以决定簇内节点地址更新时机。仿真结果表明,该算法能够减少节点的平均地址长度,避免地址冲突,有效降低传输节点地址导致的能量消耗。
