最近一直有个疑问,当ZigBee协调器采用广播发送数据时(广播地址采用0xFFFF,也就是广播给所有设备),协调器下面的路由器收到广播信号后也是采用广播方式发送给其他节点吗? 这就是说当一个ZigBee网络中存在较多的节点时(50,到60个),协调器采用广播方式发送数据时,会不会发生广播风暴?(这里我一天广播的次数比较少)。
Viki Shi:
有这个可能,所以如果网络中节点个数多,推荐以下做法:To optimize the routing solution, many-to-one routing is recommended in such networks introduced by ZigBee-Pro 2007 to allow a data concentrator to establish routes from all nodes in the network with one single route discovery and minimize the route discovery broadcast storm.
