This paper compares QoE (Quality of Experience) of audio-video IP transmission with IEEE 802.11e EDCA and that with DCF in mobile ad hoc networks. The authors also assess QoE of the transmission with TXOP-bursting, which is an optional function of EDCA. QoE assessment of audio-video IP transmission in mobile ad hoc networks involves difficult issues. The wireless nodes can move, and then channel condition changes dynamically. The routing paths may also change as the wireless nodes move. In this paper, they tackle the difficulty of the assessment by means of a continuous time QoE assessment method, which utilizes the method of successive categories continuously in time.
