由于无线传感器网络(WSN)中的节点能量有限，能量问题是 WSN 的研究热点。首先传感器产生的数据具有时间和空间的相关性，所以让一部分传感器工作，其余休眠，可以提高网络寿命。其次移动基站以汽油为燃料，每次移动距离有限。基于以上两点考虑，提出了CMSLM(Constrained mobile of sink lifetime maximum)算法，移动基站在移动距离受限条件下，移动尽可能远的距离，减少移动移动基站的数量，此外，每个网关利用最大流构造平衡树，使得瓶颈的传感器能量消耗尽可能的均衡，从而使得网络寿命最大化。通过实验仿真显示， CMSLM比SRP-MS算法相同的周期内的死亡的节点数要少的很多。

Wireless sensor network (WSN) is made of a large number of sensors, which power is limited. The energy management is a hot issue. Owing to the relevance of time and space between sensors, we allow some sensor nodes to be alive and some sensor nodes can be turned off. Mobile sink is powered by gasoline, thus the mobile distance is limited. Therefore, we propose CMSLM (Constrained mobile of sink lifetime maximum) algorithm. Firstly, we select as little as possible mobile sinks under the condition of limited mobile distance for mobile sink. Secondly, we construct balanced tree by the maximum flow, to maximize the WSN lifetime. The experiment simulation shows that the number of dead sensors of CMSLM algorithm is less than SRP-MS.
