Cooperative Peer-to-Peer Repair for Wireless Multimedia Broadcast

Overview This paper explores how to leverage IEEE802.11- based Cooperative Peer-to-peer Repair (CPR) to enhance the reliability of wireless multimedia broadcasting. The paper first formulates the CPR problem and presents an algorithm that assumes global state information to optimally schedule CPR transmissions. Based on insights gained from the optimal algorithm, a fully Distributed CPR (DCPR) protocol is proposed. Simulation results demonstrate that the DCPR protocol can effectively enhance the reliability of wireless broadcast services with a repair latency comparable to that of optimal scheduling.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
