description The invention discloses a carrier path selection method based on beacon success rate sliding window calculation, which comprises the following steps: step 1, a carrier node periodically sends beacons, and beacon serial numbers are carried in beacon messages; step 2, the carrier node uses a bitmap with the size of N bits to record the condition of receiving the beacon of another carrier node in the past N periods; step 3, the carrier node calculates a downlink communication success rate according to the bitmap and issues the downlink communication success rate through a discovery list; 4, analyzing the discovery list of other nodes by the carrier node, and calculating an uplink communication success rate; and step 5, all carrier nodes adopt the methods from the step 1 to the step 4 to calculate the downlink communication success rate and the uplink communication success rate with the surrounding carrier nodes, and the node with the maximum product of the downlink communication success rate and the uplink commu
