RFID (radio frequency identification device) communication network group establishment method oriented to wireless sensor network application

The invention relates to an RFID (radio frequency identification device) communication network group establishment method oriented to wireless sensor network application. In the existing method, under the situation that the number of sensor nodes is large, the network establishment speed is slow. The RFID communication network group establishment method oriented to wireless sensor network application comprises the following steps: a base station transmits wake-up signals to all wireless sensor nodes, so that the wireless sensor nodes are in a network establishment working state, and then the base station pre-collects the wireless sensor nodes which do not interfere with each other; and then the wireless sensor nodes are grouped and collected until the wireless sensor nodes are accessed toa network; and finally, the base station transmits network establishment completion signals to all the wireless sensor nodes, so that the wireless sensor nodes are switched to a normal communication state from a sleep state,
