对无线传感器网络中的DV-Hop的定位算法进行了研究和分析,它是一种基于无需测距的无线传感器网络的定位算法.针对DV-Hop根据全部网络的数据计算单跳距离,通信负担大,而且对于锚节点分布不均和稀疏节点网络,定位精度差,提出把网络分局部和分区域.针对非测距算法的定位精度粗糙,在DV-Hop后,加入分布式迭代算法,进一步提高定位的精度.通过对算法的仿真,得出该算法定位精度提高,和改进算法的一些特定应用环境.
The location algorithm of wireless sensor network based on wireless sensor network is studied and analyzed, which is based on the wireless sensor network without ranging algorithm.According to the DV-Hop calculation of single-hop distance based on the data of all networks, the communication burden It is proposed to subdivide the network into sub-regions and sub-regions.For the non-ranging algorithm, the positioning accuracy is rough, and after DV-Hop, a distributed iterative algorithm is added to further improve the positioning accuracy of the network. And improve the accuracy of positioning.After the simulation of the algorithm, we get the improvement of the positioning accuracy of the algorithm and some application-specific environment of the improved algorithm.
