摘要： A technique for determining when to change a data rate by determining the cause of packet loss. The technique distinguishes between collision mediated packet loss and poor signal mediated packet loss. Rate shifting to a lower rate is performed after determining poor signals are causing packet loss. After switching to a lower rate, the packet loss rate can be compared to the pre-switch packet loss rate. If the packet loss rate has not improved by shifting to a lower data rate, then the data rate can be shifted to a higher rate. The technique can use a combination of channel response, signal strength, packet loss rate and throughput to determine when to switch data rates. A communication unit can maintain separate histories for each unit it is communicating with and employ a different data rate for each unit.

摘要： A distributed, bidirectional congestion control and starvation avoidance system for wireless mesh networks. In particular implementations, the nodes of the wireless mesh network monitor their respective local buffers for traffic load, and signal upstream and downstream nodes in response to detected congestion or excess capacity to dynamically allocate transmit capacity between neighboring nodes. Particular implementations are capable of mitigating congestion and preventing starvation in a fully distributed, low-overhead, scalable and efficient manner.

摘要： Described herein are a computer-implemented method of determining a power plan/frequency plan combination assigning transmit frequency channels and transmit powers for a plurality of managed access points (APs) of a wireless network. Also described herein is a carrier medium carrying computer readable code configured to cause one or more processors of a processing system to implement the computer implemented method of determining a power plan/frequency plan combination. The method includes determining candidate power plans for the access points, including determining candidate transmit powers for the access points, determining a candidate frequency plan corresponding to each of the determined candidate power plans using a frequency plan determining method to determine a set of candidate power plan/frequency plan combinations, and rating each combination of a candidate power plan and candidate frequency plan according to an evaluation criterion, and selecting a preliminary power plan/frequency plan combination based on the rating. One embodiment of the method further includes determining a final power plan for the preliminary frequency plan of the preliminary power plan/frequency plan combination to obtain a final power plan/frequency plan combination.
