Inter-destination synchronization quality in an integrated wired and wireless network with handover

This paper presents experimental results of inter-destination synchronization control in an integrated wired and wireless network. The experimental system consists of interconnected wired and wireless networks; the former is a router-based IP network, and the latter is a wireless LAN with two base stations. A server in the wired network multicasts a pair of audio and video streams to a terminal in the same wired network and a wireless terminal, which performs handover from one base station to the other. We exert inter-destination synchronization control between the two terminals using the synchronization maestro scheme, which the authors previously proposed. In the experiment, we measured the synchronization quality of inter-destination as well as intra-stream and inter-stream when handover occurred, and we confirmed the effectiveness of the control.
