Delay detection probability polling method, device, equipment and medium

The invention belongs to the technical field of network communication, and particularly relates to a delay detection probability polling method, device and equipment and a medium. A sink node sends a polling packet to all sensor nodes; the active sensor nodes generate random numbers, and the random numbers are compared with a preset competition threshold value in the polling packet; if the competition value is smaller than the preset competition threshold value, a delay factor is randomly generated according to the total number information of the nodes in the polling packet, and a short detection packet is sent to the aggregation node in a delayed mode according to the delay factor; the sink node receives the detection packets in a period of time and performs sequential sorting according to the delay factors in the detection packets; sequentially polling corresponding nodes by taking the delay factors as temporary numbers of the nodes according to the sorting sequence in the next polling; the polled sensor no
