Mesh Net Viewer II: An Extended Visualization System for Wireless Mesh Networks

Wireless Mesh Networks (WMNs) consist of several Access Points (APs) of Wireless Local Area Networks (WLANs) interconnected through wireless link. It is necessary to monitor the networks in order to properly operate WMNs. However, it is very difficult to always monitor WMNs. Though several researches for visualization system of WMNs were done, there are some problems such as lack of dynamic information and past information. Our previous system also had problems such as lack of visualization information and inefficient information collection method. In this paper, we propose an extended visualization system for WMNs called Mesh Net Viewer II (MNVII). MNVII can visualize not only network topology and link stability degree but also packet flow, route information and past information of WMNs. Furthermore, we have improved visualization information collection method of our previous system. In the performance evaluation, we verified visualization accuracy and real time characteristics of MNVII.
