First Claim
1. A method comprising:
- (a) providing a plurality of wireless modules;
each wireless module of the plurality of wireless modules operating according to a wireless standard;
(b) initiating an arbitrary cooperation between at least two of the plurality of wireless modules in proximity, the arbitrary cooperation established in dependence upon at least one of a sensing tone and a polling tone, the at least one of the sensing tone and the polling tone being associated with a channel according to the wireless standard.

Abstract
Within both the licensed and unlicensed wireless spectrum, benefits are obtained in allowing devices to form and communicate based upon opportunistic spectrum availability. At present such ad-hoc networks are established using either directly existing Media Access Control protocols or proposing modifications to them. According to the invention, there is provided a method for allowing abstract wireless links, i.e., arbitrary cooperation among a set of proximite wireless nodes, to be established between devices in a fast and efficient manner. Beneficially the approach allows multi-standard cognitive radios to operate in ad-hoc environments and non-ad-hoc environments. Accordingly a wireless module monitors a plurality of sensing tones and polling tones, each pair of sensing and polling tones associated with a transmission channel. A wireless module determines a vacant transmission channel by the absence of both a sensing tone and its associated polling tone. An abstract wireless link could be established by the wireless module transmitting the polling tone associated with the vacant transmission channel and detecting from second other wireless modules the sensing tone associated with the vacant transmission channel.

25. A computer readable medium having stored therein data according to a predetermined computing device format, and upon execution of the data by a suitable computing device a method of establishing an arbitrary cooperation of a set of wireless modules in proximity is provided, comprising at least one of:
-
monitoring a plurality of sensing tones, each sensing tone associated with a transmission channel; monitoring a plurality of polling tones, each polling tone associated with a transmission channel; determining a vacant transmission channel, the vacant transmission channel being determined by an absence of at least one of its sensing tone, polling tone, and data transmission; transmitting from a first wireless device the polling tone associated with the vacant transmission channel; and transmitting from a second other wireless device the sensing tone associated with the vacant transmission channel.
