| 摘 要： | 为了提高ZigBee网络的路由效率,降低节点能耗,提出一种基于节点移动性的路由选择策略.ZigBee网络同时支持基于地址分配的分层路由和基于路由请求的路由方法.该策略根据网络中节点移动性的变化,自适应选择路由方法.节点通过自身邻居参数改变识别位置变化,避免了网络中额外的数据传输流量.经仿真测试,相对于原有的单一方法路由方案,基于节点移动性的路由选择策略具有更高的路由效率,提升了ZigBee网络的路由性能.

| Abstract: | To improve the routing efficiency and reduce the node power consumption in ZigBee network,a routing selection strategy based on node mobility was proposed.Both the hierarchical routing based on address allocation and the routing method based on routing discovery are available in ZigBee network.In the strategy,the node chose the routing method self-adaptively on the basis of the change of node mobility.Nodes recognized the mobility variety through the change of parameters in neighbor table to avoid the extra network load.The simulation results showed that the routing strategy based on node mobility,compared with original single routing schemes,had better routing efficiency and improved the routing performance in ZigBee network. |
