Abstract:

Aiming at the big estimation error and the unreasonable selection to the participant positioning beacon nodes in the traditional DV-Hop localization algorithm, an improved DV-Hop localization algorithm for wireless sensor networks is proposed. The degree of collinearity method is used in the selection of the beacon node group. As long as the degree of collinearity of the beacon node group meets a predetermined range, the beacon node group will be selected. In each of these groups, the position relationship between beacon nodes and unknown nodes is discerned, the real distance between beacon nodes made full use of, and the localization of unknown nodes made by using any two estimated values, with a number of cycles in each group selecting two estimates to get a lot of unknown nodes estimate position, and finally the estimated coordinates of unknown nodes are obtained by clustering analysis in the field of data mining. The simulation shows that the improved algorithm can reduce the localization error and improve the accuracy of the algorithm and robustness without any increase in the hardware overhead, and at the same time, it is insensitive to some of the larger errors in the final result.

Key words: wireless sensors networks, DV-Hop algorithm, localization, collinearity, DBSCAN-based clustering analysis
