Modelling of multi-path transmission system of various priority multimodal information

Today multimodal approach is relevant in any sphere of our digital life. The technologies aim to suggest the best and the most comfortable way for human-human and human-machine interaction. One of the direction to do that is the usage of multimodal interaction. We consider that modalities may be different by priority. It means that some modalities are more significant than others in a particular task. In this paper, we propose the mathematical model of the multi-path transmission system of various priority multimodal information based on queueing theory. We present a multipath multimodal data transmission system as a multi-phase queuing system (QS), consisting of two typical nodes. The first node (QS1) defines the queue of packets of modalities of different priority, the second node (QS2) distributes the packets over available access networks. We build a simulated model on AnyLogic tool. We show that the rate of packets losses is significant depends on the priority level.
