Patent ID: 8514789

Claim:
A system of wireless transceivers employing cognitive channel adaptation, the system comprising: a plurality of wireless transceivers communicating over a common wireless communication channel, each of the wireless transceivers being capable of dynamically switching from a first common communication channel to a second common communication channel in response to a decision reached by at least one of the wireless transceivers based on a determination of a quality of communication environment by at least a portion of the plurality of wireless transceivers, the wireless transceivers configured to: estimate an amount of communication taking place on the first common channel by detecting a level of energy on the first common channel, receiving power emission information of one or more neighboring wireless transceivers, determining whether received packets belong to a network of the wireless transceivers, discarding samples of high energy belonging to the network of the wireless transceivers, using remaining samples to calculate channel quality by applying a predefined metric comprising one of an average of energy, a mean of energy, a cardinality of different energy values, and a threshold function, and determining the second common communication channel according to one of a Veto Voting Scheme (VVS) and a Majority Voting Scheme (MVS); and reach the decision to switch to the second common communication channel based on one of: determining that a maximum interference for the wireless transceivers on the second common communication channel is less than a maximum interference on other available communication channels and determining that the second common communication channel provides a better quality of communication environment for at least a majority of the wireless transceivers relative to the other available communication channels.
