Multi-dimension resource allocation algorithm based on QoS guarantee in dense WLAN

Abstract

A multi-dimension radio resource allocation method was proposed to improve the network performance in dense WLAN.By joint evaluation of the network covering,interference between cells and user's QoS satisfaction,the object function of the radio resource allocation was founded and tabu search method was used to find the optimum solution of the object function.The optimum solution is the resource allocation vector including the best AP set,AP's channel set and power set.The simulation results show that the proposed method improves the network performance and provides a better guarantee of user's QoS requirement.
