Abstract
Previously, the distributed coding aware routing (DCAR) mechanism was proposed as a network coding aware routing protocol. However, DCAR is inefficient in handling realtime multimedia flows because it prefers nodes with longer queues in determining routes so that network coding opportunities can be increased. We propose a distributed coding-aware routing protocol that can maximize throughput and minimize delay of real-time multimedia flows in wireless multi-hop networks. Simulation results show that our proposed scheme achieves higher throughput and reduces the average end-to-end delay compared to the traditional distributed coding-aware routing protocols.
