Peer-Assisted Video-on-Demand in Multi-Channel Switching WiFi-Based Mobile Networks
Network convergence paradigm will substantially increase the pervasive use of Wi-Fi-enabled smart mobile devices. Although various on-demand streaming services are already available over mobile Wi-Fi-enabled devices, it remains a challenging problem due to Wi-Fi's limited communication range, mobility and user population density issues. In this paper, the authors enhance their previous work on MOVi (Mobile Opportunistic Video-on-demand) by exploiting the use of multi-channel switching capability at mobile terminals. They reinvestigate the previous version of MOVi in this environment and propose an improved scheduling algorithm which incorporates collaborative congestion sensing and efficient channel allocation mechanisms.
