Cost Analysis of Multicast Routing

Chapter 9 investigates the cost of packet delivery and location update cost of different mechanisms for multipoint data transfer in UMTS networks. First, an alternative mechanism for performing multicast routing in UMTS networks is described. Then, cost expressions for the packet delivery and location update cost of several mechanisms for multipoint data transfer such as MBMS are derived. Finally, the performance of the proposed mechanism for routing multicast packets in UMTS is evaluated numerically and compared against that of MBMS and other viable mechanisms for multicast data transfer
