Abstract
Network coding has recently attracted attention as a substantial improvement to packet retransmission schemes in wireless multicast broadcast services (MBS). In this paper, we are interested in applying the maximum clique approach to the network coding based multicast retransmission problem in the MBS systems. Our figure of merit is the transmission efficiency which is an important design parameter for some MBS systems, such as the satellite broadcasting networks since it affects the energy efficiency and delay of the system directly. We show that introducing the idea from network coding allows us to realize significant benefits in terms of transmission efficiency for the problem of multicasting and broadcasting, and develop an algorithm that allow to realize these benefits in practice.
