Performance Study of ZigBee Wireless Sensor Network for 500kV UHV Transmission Tower

Transmission smart towers have a wide variety and large number of embedded sensor nodes. By modelling and simulating the structure of a wireless sensor network based on the ZigBee protocol for transmission smart towers using OPNET, the performance metrics such as MAC layer throughput and application layer end-to-end delay of star, tree and mesh networks are compared and analyzed under the same attribute configuration. A ZigBee wireless network topology suitable for 500kV ultra-high voltage(UHV) transmission towers with a large number of embedded sensing nodes is selected. The combination of transmission smart tower application scenarios and OPNET simulation results show that the mesh structure is suitable for the ZigBee wireless networking topology of transmission smart towers with a large number of embedded sensing nodes.
