Other AbstractThe invention relates to a path-repair-based path maintenance method facing a wireless sensor network. The method comprises the following steps: when wireless sensor node message transmitting and ACK message receiving ratio reaches a predetermined threshold value, the path segment is marked to be the damaged state; a path repair request message is sent by a wireless sensor node to a wireless network management center through a shared path; communication resources of the wireless sensor node and other shared nodes are redistributed by the wireless network management center; and the path is reset to the health state by the wireless sensor node. According to the invention, the method can be used to fast find whether a path is damaged, so the path can be repaired fast, the path robustness can be improved, and the communication success rate can be improved; during the path damage process, messages are transmitted through a redundant path or a shared path, so the communication success rate can be improved; according to the invention, no additional communication resource overhead, such as the time slot, the channel, etc., is generated in the wireless sensor network path maintenance process, and no additional path maintenance message is generated, so the power consumption overhead can be reduced.
