Granola: A location and bandwidth aware protocol for Mobile Video on-Demand systems

Due the development of new wireless technologies and the advent of new mobile devices, new services and applications are necessary to supply the needs of the users of these devices. Video on-Demand (VoD) services have become one of these services. In this paper we present a P2P Mobile Video on-Demand (VoD) Protocol for mobile devices. Due to different possible communication interfaces that are available for mobile devices, we considerer that they can be in networks with different throughput characteristics, and also, they can be distributed through the Internet. Therefore, the proposed protocol allows the building of content distribution trees in the application layer considering two major aspects related to mobility: the bandwidth available that the mobile device can share with the network, and; the relative position of the mobile device in the network. Also it is presented simulation results of our protocol, and a performance analysis against the traditional Client-Server design.
