Abstract
Described is a protocol by which wireless network communication devices comprising peer nodes (such as a computer system and an access point) cooperatively exchange information about RF interference detected in the network. The protocol administers the exchange of formatted control data corresponding to the detected interference among computing nodes running a service capable of processing the control data. A peer table is used to maintain locally-obtained and remotely-obtained control data. Records in the peer table are arranged with different levels of granularity with respect to interference and networking information. The interference information collected through the cooperative protocol may then be used by peer devices in the network to adapt to mitigate interference-related problems. The protocol also provides for discovery of peer node capabilities, including a negotiable transport for the control data that may be different from the main data channel transport.
