Recently, providing reliable transmission over satellite networks is still a challenging problem due to the dynamic changes of the satellite topology, the large delay and the high error rate of the satellites’ links. The benefits of network coding are well understood to solve those problems above for a large class of wireless networks. In this paper, a new coding-aware routing algorithm is proposed to decrease the large delay and improve the transmission efficiency by performing network coding opportunistically instead of using network coding always or using the shortest path routing only. The theoretical analysis and simulation results show the correctness and effectiveness of the proposed algorithm.
