摘要
基于传统DV-Hop算法的定位技术,通过分析该算法误差产生的主要原因,提出了节点间跳数的修正方法。通过在广播通信中采用双通信频率,将节点间的跳数缩减为0.5R,减少了平均跳距的误差。通过matlab软件的实验验证,本算法可以提高节点定位精度,且提高网络通信频率,可进一步提高定位精度,定位结果达到了预期的目的。
Based on the traditional positioning technology of DV-Hop algorithm, through analysis of the main reason for the error occurring in the algorithm, this paper proposes the correction method of Hop count between nodes. Double frequency is used in radio communication. The hop count be- tween nodes can be reduced to 0.5R, which can reduce the average jump distance error. Through matlab software experimental verification, this algorithm can improve the node location accuracy. The higher frequency of network communication can further make the positioning accuracy lower. Po- sitioning results reached the expected purpose.
