Abstract(in English) In a wireless communication system, mobile stations (MS) in low-quality channels degrade the total system performance since the radio bandwidth and power are shared with other MSs. Therefore, MS position is one of the most important factors for radio resource control. In this paper, we propose a station reallocation method. The proposed method optimizes MS locations based on an indicator, called "Gain". The gain is given by increased utility and movement cost. The utility is defined as willing-to-pay (WTP) in this paper reflecting QoS (Quality of Service), while the movement cost is defined as payment to users' movements obtained by questionnaire survey. The proposed method is designed and evaluated in IEEE 802.11a wireless local area network (LAN) to demonstrate the effectiveness of our proposal. Furthermore, performance of a simplified reallocation algorithm to avoid computational compelexity is compared with the optimal solution.
