| 摘 要： | 无线簇树网络可以支持实时、确定的通信活动,但由于实际应用中的设备间位置关系,会产生簇间通信冲突,从而影响系统的实时性能。基于IEEE 802.15.4标准,本文系统地研究簇树网络中实时通信的冲突问题,提出避免簇间超帧冲突的算法。具体实例分析表明,该算法可以解决无线簇树网络实时通信中的冲突,并可以提高整个网络的通信性能。

| Abstract: | Wireless cluster-tree networks can support real-time and deterministic communications.But for the device deployments in practical applications,communication collisions can occur between clusters and influence real-time performance of the systems.Based on IEEE 802.15.4 standard,this paper studies the collision problem of real-time communication in wireless cluster-tree networks,proposes a superframe collision avoiding mechanism between clusters.The example analysis shows that the algorithm can solve the collision of real-time communications in wireless cluster-tree networks and improve performance. |
