This study addresses an efficient cooperative game-theoretic channel access scheme for data offloading and cooperation of emergency user using cooperative cognitive ad-hoc controllers in order to reduce the blocking probability of the newly incoming emergency user. The main objective is to connect all the users who are in need of urgent spectrum and it is considered that their data size is too large. Also, a hybrid overlay-underlay approach was undertaken which provides higher spectrum flexibility. A distributed algorithm is proposed which comprises a criterion assignment, merge and split algorithm and an auction mechanism to provide incentives to those controllers who participate in cooperation. An aggregate throughput of 18% is obtained as an improvement when compared with other conventional heuristics algorithm. 收起
