摘　　要：在无线传感器网络(W SNs)中,为了能有效降低生成簇的簇树高度,需要设计可以限制节点到基站最小跳数的分簇算法,介绍了一种基于梯度场的拓扑控制算法(ETBG),并针对该算法中由新节点加入或节点死亡引起的拓扑结构变化的情况,给出其维护和更新算法,使该算法具有更好的可扩展性和自恢复能力,最后通过M atlab仿真验证算法的有效性。In wireless sensor networks,in order to reduce the height of clusting tree,it is necessay to design an algorithm which can limit the least hops from nodes to the base-station.The energy-aware topology control protocol based on gradient（ETBG）algorithm is introduced and its maintenance and updating algorithm in the light of topology changes caused by new nodes join or nodes death is proposed.The simulation results demonstrated that they are effective.
