摘　　要：研究异构传感网节能优化拓扑控制优化问题.在异构传感器网络中,每个传感器节点普遍存在初始能量异构,节点在无线通信过程中通信链路异构等异构现象.为了延长网络的生存期,提出一种自适应优化异构无线传感器网络拓扑结构控制算法.算法主要难点技术问题在于对参数E的选择控制问题.该算法基于传输数据跳数和相邻传感器之间通信距离,依据相似三角形几何原理,结合具体应用场景对传感器节点的分簇、成簇等操作进行自适应优化控制.仿真实验表明,改进的算法可以高效控制给定数据采集监测区域所有节点的网络拓扑同时极大地延长了异构传感网的生命周期.In the Heterogeneous sensor networks,each be initial energy sensor node widespread in Heterogeneous wireless communication,the nodes in the process such as communications link heterogeneous phenomenon.In order to prolong the network life period,this paper proposes an Adaptive optimization heterogeneous wireless sensor network topology structure control algorithm（Adaptive VAP-ED）.The algorithm,based on data transmission experience of hop and between adjacent sensors,according to a jump communication distance geometry theory,combined with similar triangle concrete application of sensor nodes scene clumps,clusters operation are adaptive optimal control.Simulation experiments show that the algorithm can efficiently control the given data acquisition monitoring area all nodes network topology and greatly extend the life cycle of heterogeneous sensor network.
