Optimal Sensing Slots Determination for UAV under Correlated Log-normal Shadowing

Due to spectrum congestion, cognitive radio technique should be adopted by UAVs to improve their communication capability. Under the constraints of missed detection probability and false alarm probability, the less the sensing slot, the longer the transmission slot and the greater the throughput in a sensing period. In this paper, the sensing performance of UAV under the correlated log-normal shadowing is analyzed, and a method for determining the optimal sensing slots of UAV is presented.
