摘要：在基于测距的无线传感器网络定位中,获取相邻节点距离值时,往往包含着环境中的各种干扰。为了减少环境干扰对定位精度的影响,在加权定位方法的基础上,利用未知节点附近满足一定距离要求的锚节点,对定位后的节点坐标值进行校正,以达到降低定位误差的目的。仿真结果表明:该方法简单,对降低定位误差有很好的效果。
For the localization of WSN based on distance,the distances between neighbor nodes often contain various disturbances from the environment.In order to attenuate the effect of disturbance for the localization accuracy,an updating algorithm is proposed in which the beacon nodes near the unknown nodes and satisfying some distance requirements will be utilized to regulate the position obtained from the weighted localization methods.It is shown from simulation results that the proposed method is simple and can effectively reduce localization errors.
