Modelling of VoIP Based Tele-teaching System: A Petri Net Based Approach
In this paper we propose an algorithm called Interactive Group Synchronization to reduce the chance of audio speech overlapping in VoIP based conferencing. We also extend the capability of colored petri nets by introducing time parameter in it. The propose TCPN (Time Colored Petri Nets) tool is applied here to model the interactive group synchronization algorithm in teleteaching system and then verify and check the correctness of the model.
Keywords: VoIP, Tele teaching, Synchronization, Algorithm, Modelling, Verification, Petri Nets.
