Research of an Adaptive Node Deployment Technology for Multi-sensor Networks

基于多传感器节点圆形数据采集区域相切形成一系列相似三角形在几何原理上的有效性和可行性,提出了一种基于相似三角形的网络节点协同控制节点部署技术.首先把数据采集区域分割为多个几何相似的三角形,保证对监测区域无缝覆盖的同时聚集最少的传感器节点;其次在簇首节点与分簇区域内的传感器节点之间构建高效拓扑;然后建立一种自适应节点失效重建网络拓扑控制机制.仿真实验表明,该节点部署算法可以对监测区域实现完全无缝覆盖,保持网络整体性能高效以及数据传输的可靠性..

Based on multi-sensor node circular data acquisition area form a series of similar triangle tangent in geometrical on the effectiveness and feasibility,this paper puts forward a method based on similarity triangular network node coordination control nodes deployed technology.First put data acquisition regional segmentation for multiple geometric similar,guarantee the triangle of monitoring area seamless coverage while gathered least sensor node.Secondly in cluster head nodes and clumping area between the sensor node constructing efficient topological.Then build a kind of adaptive node failure rebuild network topology control mechanism.Simulation experiments show that the nodes deployed algorithm is able to monitor the area completely seamless coverage,keep the overall performance of data transmission efficiency and reliability.
