Patent ID: 8817640

Claim:
A method for a node to select triggering events for multimedia applications in a decentralized wireless access control system, said method comprising: updating a history record, by said node, for each of a plurality of candidate events, said candidate events being in a complementary triggering set, said updating of said history record being performed by carrier-sensing; first determining, by said node, a busy index for each of said candidate events; second determining, by said node, a selection probability responsive to said busy index, wherein said selection probability for candidate event k is given by q ⁡ ( k ) = BI ⁡ ( k ) - 1 ∑ i ∈ Q ~ T ⁢ BI ⁡ ( i ) - 1 , where BI(k) is said busy index for one of said candidate events (k), and ∑ i ∈ Q ~ T ⁢ BI ⁡ ( i ) is the summation of the busy indices for each of said candidate events in said complementary triggering set; and selecting, by said node, one of said plurality of candidate events in said complementary triggering set for insertion into a triggering set responsive to said selection probability.
