Zigbee网络环状分层方法的仿真与实现

Simulation and realization of zigbee network annular stratification

摘要:

针对Zigbee网络原有分层方法的不足,提出了Zigbee网络环状分层方法．采用改进的洪泛路由方法加以实现,通过在洪泛路由方法中加入层数更新机制与帧转发控制机制,避免了资源浪费与数据内爆问题,优化了环状层次结构的建立过程．仿真结果表明:环状分层方法效果优于Zigbee的簇树状网络的分层方式,且在均匀网络和非均匀网络两种情况下,改进的洪泛路由方法均可建立环状层次结构．最后在CC2430硬件平台上验证了环状分层方法的可行性．

Abstract:

Aiming at the shortage of Zigbee network stratification, the annular stratification is introduced. The improved flood routing which is combined with the mechanism of updating stratification and the mechanism of frame transmit is adopted to achieve the target. The wastes of resources and data implosion are avoided by using the improved flood routing. And the process of establishing annular stratification structure is also optimized. The simulation result shows that the improved flood routing is suitable for uniform network and non-uniform network. At last, the improved flood routing is carried out on the CC2430, and the real results match the expected results.
