Abstract
With the development of the theory and technology of wireless sensor networks (WSN), location-based applications, such as location-based access control, pose new challenges. In order to improve the accuracy of node localization, the energy consumption must be considered in conjunction with security. Improving the accuracy of node localization as much as possible under the premise of ensuring the security of the localization process forms the basis of location-based applications in wireless sensor networks. In this paper, a secure localization method of nodes based on the congruity of time is proposed. This method does not need to meet time synchronization conditions between user nodes and base stations. It calculates the congruity of time according to the communication delay between nodes, and then estimates the location of the user node. It can ensure the accuracy of localization and the security of localization processes.
