Abstract :
The few existing IP hand-off methods that support multicast are not really practical. This paper proposes a seamless hand-off method for multicast receivers. The proposed method observes the wireless link connection intensity to setup the multicast stream in the new subnet in advance while terminating the old connection more rapidly. Computer simulations verify that our method minimizes packet loss caused by hand-off and the needless transmission of multicast packets by the old subnet to use bandwidth more effectively.
