一种改进的无线传感器网络非测距定位算法

节点定位是实现传感器网络应用的前提,控制节点定位误差成为保证网络正常运行的关键。采用基于测距的定位算法,可以达到良好的精度,但需要测量装置,不适合能量受限的无线传感器网络。本文分析了常用的非测距定位算法,并在此基础上提出了一种改进的基于序列的非测距定位算法,以提高无线传感器网络定位算法的性能。

Advanced Range-free Position Algorithm in Wireless Sensor Networks

Node position is the prerequisite in wireless sensor network applications,so the control of node position error becomes a key to ensure normal running of networks. Range-based position algorithm can achieve good accuracy, but it requires measuring devices, thus it is not appropriate for large-scale wireless sensor networks. This paper analyzes popular range-free position algorithms and proposes advanced sequence-based range-free position algorithm to improve the performance of position algorithm in wireless sensor networks.
