Unicast and Multicast: A Unifying Handover Paradigm

While existing research has been focussed on supporting handovers of unicast connections, handovers of multicast connections have not been investigated.

Since multicasting supports many applications that require multi-party communications, handovers of multicast connections have become a concern.
