Risk-Aware Beacon Scheduling for Tree-Based ZigBee/IEEE 802.15.4 Wireless Networks
Li‐Hsing Yen, Yee Wei Law, Marimuthu Swami Palaniswami · 2008
In a tree-based ZigBee network, ZigBee routers (ZRs) must schedule their beacon transmission times to avoid beacon collisions. The beacon schedule determines packet deliv- ery latency from the end devices to the ZigBee coordina- tor at the root of the tree. Traditionally, beacon sched- ules are chos
