摘　　要：针对传感器网络中MAC地址在通信时能量开销太大的问题,提出了一种新的适用于节点密集分布的MAC地址复用压缩算法。该算法将传感器网络节点进行区域网格分割,节点以区域为单位进行地址复用。为削弱因网络节点分布的非均匀性带给算法性能的负面影响,提出了通过标志位标识的非对称性MAC地址分配原则。理论和实验结果表明,该算法在密集型传感器网络中且节点分布不均匀情况下能很好的发挥地址压缩性能。Aiming to decrease the energy consumption of MAC address in wireless sensor networks, we propose a new MAC address multiplexing compression algorithm. In our proposed algorithm, nodes＇ addresses are multiplexed using regional grid segmentation, which on a regional basis. An asymmetry MAC address allocation principle allocation using bit f/ag is also presented, which can weaken the negative effects for irregular distribution of sensor nodes. Theoretic analysis and experimental result shows that our algorithm plays a good performance in the situation that the wireless sensor networks are intensively deployed and the distributions of nodes are irregular.
