Performance Gains of Network Coding in Evolved 3G Mobile Network for MBMS

3GPP has defined a Multimedia Broadcast and Multicast Service (MBMS), which is a major enhancement in the downlink of the 3G standard. The focus of MBMS is on the efficient management of radio and core network resources while reusing as much existing functionality as possible. On the other hand, Network Coding has been proved that can achieve the throughput capacity of an arbitrary multicast session by allowing intermediate nodes encode the incoming packets before forward. In this paper, we focus on the performance of random network coding for MBMS in evolved 3G mobile network. Basis on the architecture of multiple cell service of MBMS, we propose a multicast scheme using random network coding (RNCM). In this scheme, we integrate the capability of random network coding and the several service channel provided by the Base Stations (BS) in a MBMS cell. The simulation results show that RNCM scheme can increase the throughput of network significantly.
