| 摘 要： | 为了提高无线传感器网络节点定位精度,在DV-Hop算法基础上提出一种加权平均跳距定位算法IDV-Hop(Improved DV-Hop).根据 DV-Hop使用简单平均跳距计算节点间距离,导致较大误差这个特点,为了减少误差新算法采用加权平均跳距代替简单平均跳距.仿真实验结果表明,与DV-Hop算法相比,IDV-Hop算法有效地减少了距离计算带来的误差,提高了定位精度,能更好地满足实际应用的需求.

| Abstract: | To improve node localization accuracy in wireless sensor networks,a weighted average hop-distance localization algorithm called IDV-Hop(Improved Distance Vector-Hop,IDV-Hop for short) is proposed,which is based on DV-Hop algorithm.Based on the characteristic of using simple average hop-distance to calculate the distance between nodes in DV-Hop algorithm,which brings lager loca-lization error,in order to reduce error weighted average hop-distance is used instead of simple average hop-distance.The experimenta... |
