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.

Key words: cluster-tree network, IEEE 802.15.4, real-time communication, superframe, collision-avoiding
