Feasibility of Multi-View Video Streaming Over P2P Networks

We propose to stream multi-view video over a multi-tree peer-to-peer (P2P) network using the NUEPMuT protocol. Each view of the multi-view video is streamed over an independent P2P streaming tree and each peer only contributes upload ca-pacity in a single tree, in order to limit the adverse effects of ungraceful peer departures. Additionally, we introduce a quick join procedure to reduce the start-up delay for the first data packet after a join request. Continuity index and decoded video quality performance for simulcast and MVC encoding in a large topology under different settings are reported, in addition to the improvements achieved by the quick join pro-cedure

Mobility management in B3G networks: a middleware-based approach

International audienceThe B3G (Beyond 3G) networking will enable mobile users to roam freely through heterogeneous networks on an all-IP platform. However, mobility handling in such an environment poses new challenges. Traditionally, mobility protocols such as Mobile IP, SIP and SCTP are used to manage mobility in B3G, but they require telecommunication companies to either modify existing network infrastructures or deploy central entities in the network core to handle mobility. This is not feasible in a fully distributed computing environment (e.g., P2P) and mobile ad hoc networks that are part of B3G networking. As an alternative, this paper introduces a middleware component with modularized functionalities to facilitate mobility management in a fully distributed B3G environment
