提出一种新的定位算法。该算法中

各节点感知周边的节点密度

基于此对周边锚节点分区

利用相同区域的锚节点执行定位计算。通过仿真验证

在节点分布密度不均的网络中

该算法有效地降低了未知节点的定位误差

提高了定位精度。

Abstract

By analysis and simulation

a conclusion shows that DV-Hop

a range-free localization algorithm for wireless sensor networks

is not appropriate for the networks which are not unified in density.A new localization algorithm is proposed.In this algorithm

each node senses the density of its neighbor nodes

divides the anchor nodes into different areas according to the density and localization calculation is carried out using the anchors

which belong to the same area.According to the simulation results

in the networks which are not unified in density

the new algorithm can effectively reduce localization error of unknown nodes and increase localization precision.
