改进的DV-Hop算法在节点定位中的应用研究

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0.5 R,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和网络通信频率,可进一步提高定位精度,定位结果达到了预期的目的。

Research on the Application of the Improvement of DV-Hop Algorithm in the Node Localization

Based on the traditional positioning technology of DV-Hop algorithm, through analysis of main reason for the error occurred in the algorithm, the correction method of hop count between the nodes was proposed. Double frequency was used in radio communication,the hop count between the nodes can be reduced to 0.5 R, 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. Positioning results reached the expected purpose.
