EX-OR Opportunistic Multi-Hop Routing for Wireless Networks
Abstract
This paper describes ExOR, an integrated routing and MAC protocol that increases the throughput of large unicast trans- fers in multi-hop wireless networks. ExOR chooses each hop of a packet’s route after the transmission for that hop, so that the choice can reflect which intermediate nodes actually received the transmission. This deferred choice gives each transmission multiple opportunities to make progress. As a result ExOR can use long radio links with high loss rates, which would be avoided by traditional routing. ExOR in- creases a connection’s throughput while using no more net- work capacity than traditional routing.
