摘  要:无线传感器网络中基于节点剩余能量簇头选举算法(MLEACH)是在LEACH协议基础上得到的改进算法,能有效地延长网络的生存时间,改善了网络性能。本算法的关键是设置合理可行的选举系数,它决定了簇头选举时间和轮数。本文提出了选举系数的确立方法,并进行了模拟仿真,试验结果表明:选举系数与节点数目、簇成员节点能量消耗成正比,与簇头节点能量消耗成反比。The wireless sensor network, cluster-head election algorithm based on residual energy (MLEACH) is the improved algorithm based on the LEACH. In MLEACH, the networks alive time is prolonged and the performance is improved effectively. Establishing the reasonable and viable election coefficient is the key of this algorithm, it decides the time of change cluster node and the round. The paper not only provides the establish method of election coefficient. but also simulates it. The simulation results show that the election coefficient is direct ratio to the node number and the energy consume of cluster member, and inverse ratio to the energy consume of cluster node.
