AP Connection Method for Maximizing Throughput Considering Moving User and Degree of Interference Based on Potential Game

For multi-transmission rate environments, access point (AP) connection methods have been proposed for maximizing system throughput, which is the throughput of an entire system, on the basis of the cooperative behavior of users. These methods derive optimal positions for the users’ cooperative behavior, which means that new users move to improve the system throughput when connecting to an AP. However, conventional methods only focus on increasing the transmission rate of new users without regard to the performance impact on existing users. In addition, these methods do not account for co-channel or stacked frequency interference between users. In this paper, we propose a novel approach to access point connectivity which maximizes the system throughput by taking into account the interference between users and the initial position of all users. In addition, our proposed method can improve system throughput by about 6% at most compared to previous methods.
