Joint Source-Network-Channel Coding for Multimedia Communications
In this paper, a joint optimisation of source, channel and network coding is designed using network coding approach. This is necessary for optimal allocation of network resources at different layers. The proposed scheme is applied to satellite network and examined for bandwidth optimality. Simulation results have shown how information exchanges are efficiently performed by exploiting network coding. Thus substantial throughput is achieved to meet the challenges of multimedia communications. Network throughput can be defined as the average rate of successful message delivery over a communication channel. The throughput of information transmission within a data network is a function of network topology and link capacities.
