P2MVOD: peer-to-peer mobile video on-demand

We propose a new form of distributed multimedia communication, peer-to-peer mobile video on-demand (P2MVOD), that enables users to share an unlimited amount of video content without spatial and time constraints. P2MVOD allows a moving client to receive streaming data on demand from other moving clients in a peer-to-peer (P2P) architecture. Our scheme uses multicast VOD technology. To overcome mobile routing overhead and the service vulnerability of P2P, it divides video content into the same sized segments and broadcasts them from multiple clients. Broadcasting obviously consumes much bandwidth, but the segment aggregation allows content to be received by as many clients as possible, thus counteracting the resulting increase in traffic. Numerical analysis revealed the characteristics of the broadcast traffic on a network, the effectiveness of the segment aggregation, and the range of applications
