摘　　要：提出了一种适用于无线传感器网络的基于自适应定时器策略的分簇算法,该算法通过自适应调整节点的等待时间来保证较多电池能量的节点有更大的机会成为簇首.理论分析表明该算法不仅实现了系统的动态负载均衡,并且能够通过参数的设置确保簇首的均匀分布.仿真结果显示该算法有效地延长了系统生命,提高了网络的能耗效率.We present a timer-based distributed clustering algorithm. By adaptively adjusting the wakeup rate of the exponential distribution, a node with higher residual energy is more likely to be elected clusterhead. Moreover, the algorithm is able to ensure that clusterheads are well scattered. Simulation experiments illustrate that our algorithm is able to significantly prolong system life compared with previous ones.
