Distributed Dynamic Mobile Multicast

Traditional mobile multicast schemes have either high multicast tree reconfiguration cost or high packet delivery cost. The former affects service disruption time while the latter affects packet delivery delay. Although existing region-based mobile multicast schemes offer a trade-off between two costs to some extent, most of them do not determine the size of the service range, which is critical to network performance. In this paper, the authors propose a novel approach, called Distributed Dynamic Mobile Multicast (D2M2), to dynamically determine the optimal service range according to the mobility and service characteristics of a user. They derive an analytical model to formulate the costs of multicast tree reconfiguration and multicast packet delivery.
