Example Embodiment
[0023] The present invention will be further explained below in conjunction with the drawings and specific embodiments.
[0024] The wireless sensor network is composed of sensor nodes and a small number of actuator nodes and randomly deployed in the sensing area. Once the deployment is completed, the nodes will try to find other nodes and form a connected network through the existing technology. The area to perform tasks or improve network connectivity can be moved according to the needs of the application, such as figure 1 As shown in the wireless sensor network connection recovery system model diagram, an actuator node collects data from its neighbor sensor nodes and cooperates with other actuator nodes. Some key actuator nodes can pass through a long communication link (satellite) Connect to the command center in the remote area to report his activity status and detected events. The specific connection recovery steps are as follows:
