摘　　要：对Zigbee标准中的树型结构进行了扩展,提出了一种两级树的网络模型。该模型将整个网络分为两级,以主协调器和相关节点组成一个第一级树;将第一级树中的若干路由器作为从协调器,与周围孤立节点构建若干个第二级树,共同组成一个具有两级树拓扑结构的网络。该模型不仅起到了扩大网络规模的作用,而且路由器可以直接根据数据包的目的地址进行路由,不需要构建任何与路由相关的表项,从而减少了资源的消耗。The tree topology in Zigbee specification is extended,and a two-level tree architecture is proposed.This architecture divide the network into two levels,with main coordinator and related nodes as one first-level tree and some routers in the first-level tree and the isolated nodes as several second-level trees.Then a tree routing algorithm for this two-level architecture is proposed.This architecture could help extend the scale of the Zigbee network,and adapt the tree routing algorithm with which the packets could be forwarded directly according to its destination address,and also the router needs no route table,thus reducing the resource consumption.
