A Dynamic Service Range Management Strategy for Improving Mobile Multicast Protocol Performance
There are many challenges when providing multicast services to mobile hosts (MHs) since host’s mobility may cause tree reconstruction, non-optimal routing and the disruption of multicast services. Generally, frequent modifications to multicast tree are avoided as the expense of multicast routing inefficiency and vice versa. Two basic mechanisms, proposed by the IETF in Mobile IP to support multicasting, are two typical cases. This paper introduces a new mobile multicast approach with dynamic service range, which eliminates unnecessary tree reconstruction overhead by utilizing the state of multicast agent, and does not induce significant multicast delivery overhead at the same time. In addition, we present a previous subscription mechanism, which can resume multicast delivery quickly after a MH performs handoff. Simulation results show that the proposed protocol gets an improved performance over the existing protocols in terms of signaling overhead and delay.
