ROUTING PROTOCOL FOR A NETWORK EMPLOYING MULTI-USER WIRELESS CHANNELS
First Claim
1. At a first station of a wireless network, a communication method comprising the steps of:
- receiving from a second station of the wireless network an incoming solicitation message that identifies a first traffic flow handled by the second station as a candidate for rerouting; and
evaluating whether rerouting of the first traffic flow through the first station for being handled using one or more multi-tier signals is capable of increasing data throughput for the first traffic flow without decreasing one or more data throughputs for respective one or more other traffic flows presently handled by the first station.

Abstract
A routing protocol, according to one embodiment of which a first station of a wireless network monitors its outgoing transmissions corresponding to a traffic flow for occurrence of multi-tier signals and for ability to achieve a specified minimum transmission rate. Based on the monitoring, the first station may transmit an outgoing solicitation message that identifies the monitored traffic flow as a candidate for rerouting. Upon receipt of the solicitation message, a second station of the wireless network evaluates whether rerouting of the monitored traffic flow through the second station is capable of increasing data throughput for that traffic flow without decreasing data throughputs for other traffic flows presently handled by the second station. Based on this evaluation, the second station may transmit to the first station an offer to reroute the monitored traffic flow. The first station, in turn, evaluates this offer, e.g., by comparing its benefits with those of alternative offers that the first station might have received from other stations of the wireless network in response to the solicitation message. Based on the latter evaluation, the first station may reroute the monitored traffic flow through the station whose offer is deemed preferable.

12. At a second station of a wireless network, a communication method comprising the steps of:
-
determining whether a first traffic flow presently handled by the second station is being handled using at least one multi-tier signal; based on said determination, transmitting a solicitation message that identifies the first traffic flow as a candidate for rerouting; and receiving from a first station of the wireless network an offer to reroute the first traffic flow through the first station, said offer generated in response to receipt of the solicitation message. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A wireless network, comprising first and second stations coupled via one or more corresponding wireless links, wherein:
-
the first station is adapted to; receive from the second station of the wireless network a solicitation message that identifies a first traffic flow handled by the second station as a candidate for rerouting; evaluate whether rerouting of the first traffic flow through the first station for being handled using one or more multi-tier signals is capable of increasing data throughput for the first traffic flow without decreasing one or more data throughputs for respective one or more other traffic flows presently handled by the first station; and based on said evaluation, transmit to the second station an offer to reroute the first traffic flow through the first station; and the second station is adapted to; determine whether the first traffic flow is being handled using at least one multi-tier signal; based on said determination, transmit the solicitation message; and receive from the first station the offer to reroute. - View Dependent Claims (20)
