As an effective approach to alleviate the spectrum scarcity problem, cognitive radio (CR) has recently attracted an increasing amount of attention. In this paper, an optimization algorithm that joints bandwidth and power allocation of hybrid spectrum sharing is proposed in CR. According to the location variation of cognitive user (CU) that adopt the random waypoint based mobility models, the state of CU can switch between Underlay spectrum sharing model and Overlay spectrum one. Simultaneously, this algorithm can maximize the channel capacity through jointly optimizing power and bandwidth of CU when the Primary User's (PU's) interference temperature and the CU's transmission can be satisfied. Simulation results show that the proposed algorithm can more effectively improve the channel capacity than the single Underlay system and traditional solutions that the bandwidth is evenly allocated.
