An application-level QoS comparison of single-stream and multi-stream approaches in a wireless ad hoc network

This work compares the application-level QoS of four schemes for live audio and video streaming in a wireless ad hoc network by simulation. There are two approaches to audio-video transmission: single-stream and multi-stream. The former transmits a single transport stream of interleaved audio and video, while the latter treats the two media as separate transport streams. Each approach has an alternative of whether media synchronization control at the destination is carried out or not. Thus, we have the four basic schemes. In the simulation, we also assess the network-level QoS. We then show that the multi-stream approach with media synchronization control is the best scheme among the four schemes.
