The Hare and the Tortoise: Taming Wireless Losses by Exploiting Wired Reliability
Multiple communication channels are common in today's consumer and enterprise networks. For example, a high bandwidth but unreliable wireless network might co-exist with a reliable wired link (EWLANs and neighborhood networks). In this paper, the authors present a system that uses this reliable wired communication channel to boost the bandwidth of the lossy wireless link. Specifically, they propose a new, efficient Partial Packet Recovery (PPR) technique and adaptive feedback mechanism specially designed to correct partial packets on an 802.11 wireless network using a wired backhaul.
