Dynamic access point approach (DAPA) for IEEE 802.11 wireless LANs

In the IEEE 802.11 standard, it provides several channels within a wireless local area network (WLAN). In the infrastructure scenario, the access point (AP) is the particular device for connecting mobile stations (STA) and wired stations. Each access point occupies one channel in WLAN. Traditionally, a STA may not play the role as AP does. However, it is possible for STAs to equip both the wireless interface and wired interface at the same time. By the software support, the APs in WLAN can be elected dynamically to obtain the best transmission status for all STAs. Based on this concept, we propose a dynamic access point approach (DAPA) to enhance the network throughput. The efficiency of proposed DAPA is evaluated by simulations. Simulation results showed that the performance of a WLAN with DAPA is better than traditional approach.
