Abstract:

Combined opportunistic routing and network coding, a new any-path coding-aware opportunistic routing scheme is proposed. For reasonably choosing candidate forwarding nodes and assigning the nodes forwarding priority, the expected coding-aware transmission metric is presented. This routing scheme takes advantage of the inter-flow network coding to reduce the transmission numbers, and then improves the transmission efficiency. As the simulation is showed, it can improve forwarding efficiency and throughput of the network.

Key words: wireless networks, network coding, opportunistic routing, coding-aware, throughput
