摘要： 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.

摘要： A medium-access-control (MAC) scheduler, according to one embodiment of which a station of a wireless network evaluates data throughputs corresponding to three different transmission configurations for transmission of a packet over a first of that station's wireless links. The first and second of those transmission configurations have the packet encoded in the first and second tiers, respectively, of a two-tier signal. The third transmission configuration has the packet encoded as a conventional single-tier signal. For each of the first and second transmission configurations, the station selects a second of that station's wireless links for transmission of at least a second packet, with the first and second packets encoded in different respective tiers of the two-tier signal. The station varies power allocation between the first and second tiers to optimize data throughput for each of the first and second transmission configurations and selects from the first, second, and third transmission configurations one resulting in the highest data throughput.
