There is a strong trend toward integrating portable computers within existing data networks. Traditional network protocols were designed assuming a static view of network connectivity. A mobile host can connect to the network from different locations at different times. This has led to the emergence of a new set of problems with regard to addressing schemes and network protocols for accommodating mobility within existing networks. The authors present a protocol for delivering a multicast message exactly once to a group of mobile destinations. The protocol is based on a system model derived from an architecture developed by J. Ioannidis et al. (1991), for mobile internetworking, relying on mobile support stations within the fixed network to communicate with mobile hosts.>
