Characteristics Analysis of an AP Selection Method Based on Coordination Moving Both Users and APs

Recently, connecting to the Internet by using the wireless LAN has become familiar. In addition, the rapid growth of wireless LAN provides a lot of the wireless LAN Internet connection service areas such as hotels, cafes and airports. Moreover, the smart phones can be access point (AP) by tethering technology. These situations yields the case that there are multiple APs in the same area. In this case, users have to select an AP. Selection of an AP a ects the large impact on the overall both system throughput (the sum of the throughput of all APs in the system) and user throughput. We have proposed an AP selection method considering cooperative moving of user and AP and evaluated its performance. However, the evaluation of throughput was insufficient. This paper shows the performance evaluation over the more realistic situation considering the join and leave of user and the number of connectable AP in order to investigate the detail characteristics of the pRecently, connecting to the Internet by using the wireless LAN has become familiar.

We also indicate that the higher throughpu- can be obtained under the above considerations compared to the existing method which the new user only moves.
