【 摘 要 】

The 802.11 networks have been commonly used for public internet access. Most 802.11 hotspots have more than one access point in an area. When these access points belong to the same network, users may choose anyone it connects to. In order to enhance the access services, some methods have been proposed. The methods allocate users to certain access point to avoid crowded and collided access. The method is referred to as load balancing. The existing work in load balancing are usually based on traffic balancing as well as cell breathing. The first one is the most common method as the cell breathing applies power reduction while electromagnetic wave travels anywhere and access point are usually in distance of low power transmitter. This paper proposes load and resource balancing where the client allocation is not only based on its load but also the access point resource. The simulation evaluation shows that the proposed method outperforms the existing one by reducing delay by 0.9%, increasing throughput up to 715 kbps and the collision probability reduces by 0.068% in average.
