毫微微小区中一种基于分组的资源分配方法
A Clustering-based Resource Allocation Approach for Femotcell
摘要
Abstract
In order to solve interference between femtocells efficiently,a distributed scheme is proposed to manage resources among femtocells. Firstly,femto access points( FAPs) are grouped. In order to solve the clustering optimization problem,an algorithm is presented based on mathematical modeling idea in Lingo. The algorithm cuts off the branches which deviate from the direction of the optimal solution by establishing the simplex tableau when the Branch-and-Bound algorithm is used to find the optimal solution. Secondly, a FAP is selected as a cluster head that is responsible for resource allocation among the femtocells in cur-rent cluster. A novel algorithm which modifies sub-channel allocation by the interference instruction matrix is proposed to allocate sub-channels. The simulation results show that the proposed algorithm for clustering optimization can not only obtain the optimal solution of the clustering optimization problem compared with other algorithms,but also improve the efficiency of searching for the optimal solution. Compared with other related schemes,the proposed resource allocation algorithm can reduce the inter-user interference and a-chieve the higher data rate fairness.关键词
