Previously, we proposed an active access point (AP) configuration algorithm with the dynamic mobile router placement using the K-means algorithm to realize the elastic Wireless Local-Area Network (WLAN) system. However, this algorithm assumed that mobile routers can be freely placed at any location in the network, although they should be managed personally by their owners and thus, it becomes unrealistic. In this paper, we consider the locations of hosts as the candidate locations for the mobile routers, because host owners may use mobile routers for the Internet access. We compare the throughput performance of the limited mobile router locations with the previous free locations using the WIMNET simulator.

BS-3-33 PERFORMANCE EVALUATIONS OF ELASTIC WLAN SYSTEM TESTBED(BS-3. Advanced Networking Technologies for Innovative Information Networks)

Islam Ezharul, Funabiki Nobuo, Lwin Kyaw Soe, Mamun Md. Selim Al, Debnath Sumon Kumar, Kuribayashi Minoru

Proceedings of the IEICE General Conference 2016 ( 2 ) "S - 76"-"S-77" 2016.3

Language：English Publisher：The Institute of Electronics, Information and Communication Engineers

The elastic wireless local-area network (WLAN) system has been proposed as an adaptive and elastic WLAN system to traffic load changes in the network. Using Linux PCs, we implemented a testbed for this system that collects necessary information for the Access-Point (AP) aggregation algorithm to determine the activation/deactivation of APs by using Linux commands. Then, it controls the active APs and the associations of hosts based on the algorithm output. In this paper, we present performance evaluations of this elastic WLAN system testbed in two network scenarios in our building.

BS-3-35 THROUGHPUT MEASUREMENTS WITH VARIOUS INDOOR AP PLACEMENT CONDITIONS FOR IEEE802.11N WIRELESS NETWORKS(BS-3. Advanced Networking Technologies for Innovative Information Networks)

Lwin Kyaw Soe, Funabiki Nobuo, Islam Md. Ezharul

Proceedings of the IEICE General Conference 2016 ( 2 ) "S - 80"-"S-81" 2016.3

Language：English Publisher：The Institute of Electronics, Information and Communication Engineers

Recently, the IEEE802.11n protocol has become popular for wireless local-area networks (WLANs). It adopts the MIMO (Multiple-Input-Multiple-Output) technology for high-speed data transmissions using multiple antennas. As a result, the device can be influenced by the installation environment in receiving/transmitting signals. This paper presents experimental performance evaluations of IEEE802.11n devices for WLAN by focusing on throughputs versus placement heights and orientations in indoor environments. Our results show that throughput performance is strongly affected by the placement heights and the orientations of access point (AP). These results should be considered in optimizing the placement of APs in the network field.

A Channel Assignment Extension of Active Access-Point Configuration Algorithm for Elastic WLAN System under Limited Channels

Md. Selim Al Mamun, Sumon Kumar Debnath, Kyaw Soe Lwin, Nobuo Funabiki

2016 FOURTH INTERNATIONAL SYMPOSIUM ON COMPUTING AND NETWORKING (CANDAR) 318 - 324 2016

Authorship：Lead author Language：English Publisher：IEEE

Previously, we proposed the active access-point (AP) configuration algorithm for elastic Wireless Local-Area Network (WLAN) systems using heterogeneous APs. This algorithm activates or deactivates APs depending on traffic demands, assuming that any active AP can use a different channel to avoid interferences among APs. However, the number of non-interfered channels in IEEE 802.11 protocols is limited. In this paper, we propose an extension of this algorithm to consider the channel assignment to the active APs under this limitation. After the channel assignment to the active APs, AP associations of hosts are improved to further minimize interferences by averaging loads among different channels. The effectiveness of our proposal is evaluated using the WIMNET simulator.
