    摘要： Wireless networking devices scan for available channels and gather data about the channels and the RF environment. Using this information, each wireless networking device determines a cost value for each available channel and a quality value for its overall RF neighborhood. Each wireless networking device select the channel with the best cost value as a candidate channel for use. The wireless networking devices may submit channel requests to the arbiter for approval. If two or more wireless networking devices are requesting the same channel, the arbiter assigns the channel to the wireless networking device with the worst RF neighborhood quality. The arbiter informs the wireless networking devices if their channel requests are approved. If a wireless networking device's channel request is not approved, the wireless networking device will rescan the remaining available channels to select a different candidate channel to be approved.

    摘要： Minimum guaranteed wireless network bandwidth is provided to client network devices by monitoring the performance of network connections to identify client network devices experiencing network congestion. Congested network connections are then analyzed to determine the source of the network congestion. Depending upon the source of the network congestion, an embodiment of the invention may undertake steps to either improve the quality of the network connection or to mitigate the impact of this network connection on other network connections. High quality network connections may be allocated additional bandwidth, airtime, or other resources to reduce the network congestion. Low quality network connections are not allocated additional bandwidth, airtime, or other resources. Instead, the impact of this network connection on the other network connections is mitigated. Additionally, the low quality network connection may be transferred to another wireless networking device that may be able to provide a better quality network connection.

    摘要： Methods and apparatus for enabling mobility of a node that does not support Mobile IP are disclosed. Access point information is maintained for all functioning access points. In accordance with one embodiment, an authoritative access point (AAP) maintains access point information for all functioning access points (APs) and sends updates for all additions or other modifications to the continually changing access point information to enable APs to store a local copy of the AP information. For instance, when an AP goes offline, the access point information for that AP will be removed from the set of access point information, and notification of this removal is sent to other APs so that the local copy of the AP information may be similarly updated. As another example, when an AP comes online, it will send its AP information to the AAP. The AAP will store the AP information and provide this new AP information to other “active” APs. The AP information preferably includes an AP subnet and a gateway. When an AP receives a data packet, the AP may compare the data packet (e.g., source address) with the AP information (e.g., AP subnet) for one or more APs to determine whether to send a registration request on behalf of the node. For instance, the registration request may specify the gateway as the node's Home Agent.

    摘要： The present invention detects a micro-roaming client in a WLAN. Once a micro-roaming client is detected, APs coordinate with each other and assign the client to a specific AP. In an embodiment, a user-configurable anchor timer for micro-roaming clients is provided, so that when the timer has expired, the client is free to roam within the overlapping cell until it becomes anchored to an AP again. In various embodiments, environmental variables can affect APs to release an anchored client to roam again. These environmental variables may include low RSSI from the client, a high percentage of frame loss to the client, or a low data rate. The present invention also provides a new protocol that is resilient and self-sustaining with minimal user configuration required.
