Is it possible... in Voip Simulation over Wi-Fi using Opennet ? #89

Hi nctu teams, I wanna ask something. Is this possible to make this simulation in SDN especially using opennet :

The situation is there is a company building where have many Wi-FI AP (examples AP 1-5) . An STA (smartphone Wi-Fi only) connect to one of AP (AP 1) in this building and make VoIP call. While make VoIP, STA change position and not in range with AP 1 so STA will send request to connect to another AP in range. In current real network VoIP will be disconnected while request to connect to another AP, and my questions , is it possible in SDN to make a simulation based above while VoIP call not disconnected while move to another AP, especially using OpenNet ?

Thanks :)

An SDN-based approach will need an SDN controller which can keep the session continuity through flow management. However, OpenNet does not include SDN controller. A possible solution is let OpenNet to prepare the emulation scenario and use a customized controller to handle the session continuity. For the customized controller, some research papers may provide more details.

By the way, we use OpenNet as the course assignment environment. The assignment asks students to observe the behavior of application-based session continuity. The session continuity is realized through SIP-based VoIP software and Mobile IP.
