Research of an adaptive energy-saving and optimization topology control for heterogeneous sensor networks

针对传统的节能优化算法没有充分考虑节点间的通信距离和节点失效后重新分簇等问题,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。提出的算法首先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, an adaptive optimization heterogeneous wireless sensor network topology structure control algorithm is proposed. The algorithm is based on hop number of data transmission and distance between adjacent sensors, according to similar triangle geometry theory combined with application scene of sensor nodes, adaptive optimal control of clustering operation. Are realized simulation experiments show that the algorithm can efficiently control all nodes network topology in given data acquisition monitoring area and greatly extend the life cycle of heterogeneous sensor network.
