“…And with the help of the information theory, there has been extensive research on how to guarantee the benefits of spectrum-leasing based CRN via optimally allocate the wireless resources among PUs and SUs [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], and a good summary of the state of the art is provided in [3,4]. Thereinto, the cooperation among PUs and SUs was commonly modeled by the convex optimization problem [5,6] where the globally optimal resource allocation is analytically derived, or by employing the widely used economical concepts, such as a Stackelberg game [2], a Nash Bargaining game [7][8][9], contract theory [10,11], auction theory [12,13], matching theory [14], etc. For example, aiming to optimally calculate the design parameters of the primary and secondary networks, [5] has considered the problem of maximizing the smaller of secondary transceiver average rates, while preserving a minimum rate for the primary pair.…”
