Dynamic spectrum access allows the unlicensed wireless users (secondaryusers) to dynamically access the licensed bands from legacy spectrum holders(primary users) either on an opportunistic or a cooperative basis. In thispaper, we focus on cooperative spectrum sharing in a wireless networkconsisting of multiple primary and multiple secondary users. In particular, westudy the partner-selection and resource-allocation problems within a matchingtheory framework, in which the primary and secondary users aim at optimizingtheir utilities in terms of transmission rate and power consumption. We proposea distributed algorithm to find the solution of the developed matching gamethat results in a stable matching between the sets of the primary and secondaryusers. Both analytical and numerical results show that the proposed matchingmodel is a promising approach under which the utility functions of both primaryand secondary users are maximized.
