In order to track the population and activity of Tibetan antelope in Hoh Xil, a quantum wireless sensor monitoring network(QWSMN) based on the quantum satellite wide-area communication networks was proposed. This network consists of quantum wireless sensors installed on the Tibetan antelope, small quantum base stations, quantum satellite signal transmitting stations, quantum satellite and quantum satellite signal receiving stations. The simulation results show that under the interference of the sandstorm, a quantum satellite signal transmitting station can cover the monitoring area of 20 106 km^2, and the network throughput reaches 40 KB/s. This network can realize large-scale monitoring of Tibetan antelope in Hoh Xil and provide theoretical basis for the construction of global wildlife monitoring network.展开更多
