Abstract:
1. A method of a mobile access node selecting a data transmission rate, comprising: receiving routing beacons from a plurality of wireless clusters, each routing beacon advertising a data transmission rate of a gateway of the wireless cluster that originates the routing beacon; identifying a set of at least one qualified routing path, the set including a best quality routing path, and other routing paths having a quality within a predetermined margin of the best quality routing path, wherein the quality of the routing paths is determined by calculating a persistence of routing beacons successfully received by the mobile access node; and selecting the data transmission rate of the mobile access node based on the data transmission rate advertised by beacons of the at least one qualified routing path, wherein selecting the data transmission rate of the mobile access node based on the data transmission rate advertised by beacons of the at least one qualified routing path comprises selecting the data transmission rate of the mobile access node to be the lowest data transmission rate advertised by beacons of the at least one qualified routing path.
