Abstract :
This paper explores how to leverage IEEE802.11-based cooperative peer-to-peer repair (CPR) to enhance the reliability of wireless multimedia broadcasting. We first formulate the CPR problem and present an algorithm that assumes global state information to optimally schedule CPR transmissions. Based on insights gained from the optimal algorithm, we propose a fully distributed CPR (DCPR) protocol. 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.
