Abstract：To solve the management problem of airport environment monitoring with visual
means, an airport network for monitoring was introduced based on the WSN technology to
achieve intelligent "unattended and inspection" monitoring mode. In order to facilitate
node layout and maintenance, the monitoring area was processed with grid. Considering the
actual condition of airport, the biggest jump number, the transmission direction, the
maximum forwarding capacity and other constraint conditions were presented to lock the
optimal solution quickly and find the best position of relay node. The network load
balancing was achieved by threshold method, and the simulation experiment and performance
comparison of node layout were carried out through MATLAB. The results show that the
proposed relay node placement algorithm with multiple constraints can effectively extend
network lifetime to realize network load balancing.
