This paper focuses on the latency due to IGMP during inter-subnet handoffs in Mobile IP multicast networks and proposes a new method for this purpose. Pre-informing the neighbor subnets about the expected mobile hosts under the shadow cluster concept and triggering the preparation phase in advance are the fundamentals of the proposal. Performance improvement achieved through the method is discussed in the paper with the particular emphasis on QoS critical applications.
