Throughput Measurement-Based Access Point Selection for Multi-rate Wireless LANs

摘要: In this paper, we propose a novel access point (AP) selection algorithm to maximize the system throughput while considering user fairness. The main idea is that when new-coming enters an overlapping area of wireless local network (WLAN), it first estimates as if were associated with each APs involved. Then chooses AP can achieve highest throughput. For existing users locate in area, they may also need change association due dynamic nature traffic load. To enable fairness among users, guaranteed minimum transmission opportunity. Another significant contribution paper find load-balancing based approaches could not maximum for multi-rate WLANs, although has been considered effective approach improve single-rate WLANs. In-depth theoretical analysis and extensive simulations are performed verify optimization
