Abstract: A key in applying networking coding techniques in wireless networks is to explore more coding opportunities. A maximal coding opportunity discovery scheme is proposed, and by combining it with existing coding-aware routing protocols, a coding-aware routing protocol termed extended coding aware routing (Ex-CAR) is presented. The protocol takes maximal coding opportunity into consideration and selects the coding node number as a metric to determine the best forwarding node along the optimal route. Simulation experiments in NS-2 show that the proposed algorithm is effective, and ExCAR can enhance the network throughput and improve packet delivery rate.

Key words:  multi-hop wireless network, coding opportunity, coding-aware routing protocol
