To tackle the spectrum sharing problem in cognitive radio,a spectrum leasing layered model is proposed and analyzed for the co-existence situation of the primary user and multiple access aware users.The competitive access between access aware users employs a distributed heterogeneous opportunistic power control mechanism,and the competition and cooperation between the primary and secondary networks are cast in the framework of sequential game.A backward induction solution approach is given for the game with completed information model,and an approximate solution approach is given for the situation with incomplete information.The theoretical analysis and simulation results have shown that the proposed model and algorithm can guarantee the reserved payment for the primary user and provide fair spectrum sharing on both the level of between primary and secondary networks and the level of within the secondary network.
