CHANNEL SELECTION IN AD HOC WIRELESS NETWORK
First Claim
1. A method of selecting a channel for a node in an ad hoc network of nodes, the method comprising:
- increasing a preference score for a channel in response to receiving a stimulatory control message associated with the channel from another node;
decreasing the preference score for the channel in response to receiving an inhibitory control message associated with the channel from another node;
selecting a channel dependent on the preference score for the channel.

Abstract
The present invention relates to channel selection in ad hoc wireless networks. The present invention provides a method of selecting a channel for a node in an ad hoc network of nodes, the method comprising: increasing a preference score for a channel (E) in response to receiving a stimulatory control message (hoot x) associated with the channel from another node; decreasing the preference score for the channel (A) in response to receiving an inhibitory control message (hoot y) associated with the channel from another node; selecting a channel dependent on the preference score for the channel.
