TY - CONF T1 - Bridging UMTS and Multicast Routing in ns - 2 T2 - First International Conference on Simulation Tools and Techniques for Communications, Networks, and Systems, Marseille, France Y1 - 2008 A1 - Christos Bouras A1 - Antonios Alexiou A1 - Andreas Papazois KW - MBMS KW - UMTS AB - In this paper, we present the design and the implementation of a novel scheme for the multicast transmission of data over Universal Mobile Telecommunications System (UMTS) networks. The proposed scheme is implemented as an ns-2 network simulator module which can be employed to investigate various aspects of UMTS multicast. Apart from the normal multicast transmission over UMTS, we consider the handling of exceptional cases induced by user mobility scenarios. The proposed scheme is in accordance with the current specifications of the Multimedia Multicast/Broadcast Service (MBMS) defined by the 3rd Generation Partnership Project (3GPP) and introduces minor modifications in the UMTS architecture and the mobility management mechanisms. The performance of the proposed scheme is validated and analyzed through simulation experiments. Finally, the simulation results are presented along with their analysis.
