Effective Access Point Selection for improving Throughput in Wireless LAN

In recent years, WLANs are widely deployed everywhere due to the low-cost and easy installation. Selecting the best access point is the major research problem. The stations in the network should get associate with the suitable access points that results in higher throughput. In IEEE 802.11 wireless networks, the simple association strategy is to get associate to the AP with the strongest RSSI value, which may cause load imbalance and may eventually leads to traffic overhead. Access point selection is still a critical problem.So, a new metric or combination of metrics has to be derived that facilitates the effective selection of an AP to achieve better throughput.
