Based on wireless sensor network(WSN) and the moving characteristics of airport passengers, this paper presents an improved WSN algorithm for airport passenger positioning. At first, this research bases on wireless sensor network. Then, the improved WSN algorithm is optimized and solved. Finally, the simulation data of airport passengers is tested. The result shows that the algorithm is superior to traditional. It has more accurate positioning, can meet the need of positioning for public places with high passenger flow rate like air...
