C2AR: Coding and Capacity Aware Routing for Wireless Ad Hoc Networks

Network coding is an efficient technique to increase network capacity. COPE is a promising forwarding mechanism which can utilize network coding in a practical way. Different routing algorithms utilizing COPE may have different gains from network coding. In this paper, we discuss the importance of coding-aware routing and the tradeoff between load-balanced and coding-aware routing. We then propose a new coding-aware routing scheme, called C²AR, which combines the advantages of load-balancing and network coding, and conduct ns-2 simulations to evaluate the performance of our proposed scheme. The simulation results show that our proposed scheme has significant improvement over coding-oblivious routing.
