Cluster tree network is a kind of classic topology of infrastructure-based wireless networks. It provides deterministic communicating path and predictable delay and can be used in the applications that require high real-time performance. Because there is no available simulating platform for wireless cluster tree network,node model and its layered protocol of IEEE802. 15. 4 cluster tree network are designed based on OPNET. Beacon-enabled super-frame with slotted CSMA / CA and GTS,network constructing,application data generating,routing and receiving are implemented. A three layer cluster tree network is established for simulation. The result shows that the model supports the communication function specified by the protocol,sends and receives real-time and non-real-time data between devices correctly and can be used in the research and analysis of wireless cluster tree networks.
