2.4GHz is the maximum frequency of sight transmit signal, so it is used by Wireless Sensor Network (WSN) based on ZigBee as high frequency signal. For the poor signal penetration, nodes transmit data only in the line of sight and long-distance data transmission is achieved by multi-hop routing. To solve this problem, this paper primarily analyzes the construction environments of WSN. Simulation of network performance in several construction environments shows that the networking of mesh network is flexible, but the delay and stability of mesh network are poor.
