    • This invention relates to a rate-adaptive method for wireless mesh network in areas of wireless networking technology. In the invention, each node in the wireless mesh network broadcasts probe packets and meanwhile receives probe packets from its neighboring nodes, and maintains a rate priority table in time based on the sending success ratio of probe packets, and then sets up a new dynamic probe queue according to this rate priority table, selectively sending all the probes with rates that are listed in the rate priority table or close to them, and the automatic rate selection is accomplished by decisions on probes' sending success ratio. This invention can adapt to the changes of the network conditions very well, and reduce the influence of route broadcast and convergence on network throughput as much as possible, and at the meantime, it takes the changes in network topology into account, thus is very suitable for conditions with a complex spatial distribution of electromagnetic waves.
    • 本发明涉及无线网络技术领域的无线网状网络的速率自适应方法。 在本发明中,无线网状网络中的每个节点广播探测分组,同时从其相邻节点接收探测分组,并根据探测分组的发送成功率及时保持速率优先级表,然后建立新的动态探测 根据该速率优先级表排队,选择性地发送所有探测器,速率优先级表中列出或接近速率优先级,自动速率选择是通过对探头发送成功率的决定来实现的。 本发明可以很好地适应网络状况的变化,尽量减少路由广播和收敛对网络吞吐量的影响,同时考虑到网络拓扑的变化,非常适合 对于具有复杂的电磁波空间分布的条件。
