Detection of coverage vulnerability boundary in wireless sensor networks based on improved DV-Hop algorithm

摘要

In order to solve the problem of low localization accuracy and detection accuracy of traditional coverage vulnerability boundary detection algorithm, a new coverage vulnerability boundary detection method based on improved Dv-Hop algorithm is proposed in this paper. In order to improve the positioning accuracy of beacon nodes in wireless network, the traditional Dv-Hop algorithm is improved. Based on the improved Dv-Hop algorithm, the nodes covering the vulnerability boundary are located, the boundary range of the coverage vulnerability is determined, and the coverage vulnerability boundary detection is completed. Therefore, compared with the traditional detection method, the proposed method has higher accuracy than the traditional method.
