Matrix network coding based multicast scheme over wireless multihop networks

With the explosive increase of smartphone users, multimedia-sharing applications requiring a high data rate multicast scheme over several-meters coverage range, e.g., video streaming and a smart class, are also rapidly emerging. In order to support such applications, matrix network coding based wireless multihop multicast scheme is proposed. The numerical evaluation results show that the proposed multihop multicast scheme gives significant performance improvement in the multicast rate and coverage. Moreover, the proposed scheme has good scalability to the network size, which is inherited from the property of network coding.
