Mobile access node channel selection within a mesh network

摘要

An apparatus and method of a mobile node selecting a transmission channel of a mesh network is disclosed. The method includes the mobile node detecting a quality of routing beacons received over a previously selected transmission channel. If the quality of the routing beacons is below a predetermined threshold, then the mobile node transmits probe requests on each of a plurality of available transmission channels. Responses to the probe request are collected from at least one upstream access nodes over at least one of the available transmission channels. A new transmission channel is selected based upon the responses received over the available transmission channels.

1. A method of a mobile node transmission channel selection, comprising:
the mobile node detecting a quality of previously selected routing path over a previously selected transmission channel; if the quality of the routing path is below a predetermined threshold, then the mobile node transmitting probe requests on each of a plurality of available transmission channels; collecting responses to the probe request from at least one upstream access nodes over at least one of the available transmission channels, wherein the responses received from the at least one upstream access node over the at least one available transmission channel comprise a quality indicator of a routing path to at least one gateway; selecting a new transmission channel based upon the responses received over the available transmission channels, wherein selecting a new transmission channel further comprises comparing the quality indicator of each path corresponding to each transmission channel of responding upstream access nodes; wherein the mobile node comprises multiple radios and the new transmission channel selection is run by a second radio while a first radio is transmitting and receiving data with an upstream access node.
