基于局部分布式优化的无线传感器网络定位算法

针对在不规则的无线传感器网络中锚节点分布稀疏，对某些节点定位造成较大误差的情况，在Anchor Selection算法的基础上提出一种局部分布式优化定位算法，采用先局部后整体的定位思想，通过几何关系优化对节点之间跳距的处理，并在定位过程中将合理估计出来的节点晋升为锚节点，为后续未知节点的定位带来更多的信息参考。实验结果表明，该算法在处理不规则网络时有较强的容错性，能得到较好的定位效果。

Localization Algorithm of Anchor Nodes in Wireless Sensor Networks Based on Local Distributed Optimization

Since there is a problem of sparse distribution of anchor nodes in the irregular wireless sensor networks,and some nodes may cause larger errors in localization,a local distributed optimization algorithm is proposed based on Anchor Selection algorithm.The ideology of the localization of the nodes in local area before that in the whole network is employed.The hop distance between nodes is optimized and some nodes obtained by reasonable estimation aer promoted as the anchor nodes in the localization process t...
