Performance improvement of mobile P2P VoD by opportunity extension

This demonstration introduces our on-going work called MOVi+ that attempts to improve the video delivery performance of MOVi (Mobile Opportunistic Video-on-demand) by scheduling segments from the whole node perspective. By deploying segment based caching-enabled switch, MOVi+ increases the opportunity which reflects the pairing chances among nodes. MOVi+ also evaluates the merit of pre-diffusion-aware scheduling to utilize the time varying opportunity as much as possible. We shows that MOVi+ can eventually service more number of mobile nodes than MOVi with lower segment missing ratio, better opportunity usage, and playout continuity.
