Abstract: Most utility based wireless resource allocation methods only focus on the optimal allocation within a base station. Because of ignoring the issue of base station selection, these methods can not achieve the optimal utility of whole network. Therefore, this paper proposes a utility based multi-base-station cooperation wireless resource allocation method, which is divided into two stages. In the first stage, base stations are selected according to their congestion degree. And in the second stage, the resource in each base station is allocated according to marginal utility. The simulation experiments show that, between the approach and the baseline method, of all the 268 base station selections there are 218 accounting for 81.3% having the same selection result and the average elapse time of the proposed method is only 0.066 s, which is much lower than the baseline method 0.926 s. These facts show the rationality of the base station selection method as well as the efficiency and effectiveness of the resource allocation method.
