....that characterize the protocol similar to [6] which provides a simulation analysis for the non fault tolerant version. We consider an operating environment with 40 MSSs and 100 MHs. A MH remains in a cell for a random time interval. The length of this interval is exponentially distributed (see [3, 10]) and its average Tcell is set to 10 seconds for each MH. The wireless coverage is complete and the message loss rate in the wireless network is 0.1 . Message losses are assumed to be independent. All MHs receive multicasts (Nr = 100) whereas a subset of them with Ns= 10 members may generate ....

....upon every move, however, which is part of the problem we were seeking to eliminate. A more thorough discussion of this problem can be found in [Chikarmane 95] 5 Related Work Several other research groups have considered multicast support for mobile hosts. For example, Brown and Singh [Brown and Singh 95] specified a protocol called RelM for providing reliable 1 X N multicast service for mobile hosts, but it is focused mainly on hosts using wireless interfaces. Their protocol operates by introducing three new entities: a supervisor host (SH) a memory management module (MMM) and a local ....

....the mobile node to receive de capsulate incoming multicast packet [9] MMP allows membership changes to be made to a multicast group G. A mobile node is allowed to join or leave a multicast group at free. The concept of dynamic group membership is similar to the host view and supervisor host [7]. To join a multicast group G in the home network, a mobile node must registrar through the home agent. In current Mobile IP, a mobility agent must also broadcast advertisement messages periodically (similar to ICMP advertisement messages) and the mobile node has to send solicitation message to ....

....the link from the service provider can be negotiated as if there were a dedicated link between the MH and the SH, which minimises the complexity of QoS renegotiation during migration. South Carolina are also engaged in an investigation into support for reliable multicast in a mobile environment [Brown,95] 3.2.6 Cost Efficient Adaptive Protocol The work of Lai at Monash [Lai,95] is concerned with developing a protocol to support advanced mobile database applications . The protocol aims to compensate for low bandwidth links and, additionally, reduce the total volume of traffic while maintaining ....

....to the group is propagated to the corresponding set of MSSs, which are responsible for sending the packet to visiting group members. To guarantee the at least once and exactly once semantics, the sender to a multicast group must maintain the list of mobile hosts that belong to the group. In [5], a reliable multicast protocol called RelM is proposed for mobile networks. A hierarchical model is employed to support exactly once delivery of multicast packets to all members of a multicast group. Multiple mobile support stations are grouped together and assigned a supervisor host. Reliable ....

....the problem of optimally scheduling multicasts in mobile cellular networks. It is important to note, however, that our focus is on efficient bandwidth management (link layer issues) rather than on higher layer protocol support for multicasting. That problem has been addressed by other authors in [3]. 1.1 Cellular Network Model We assume that a region is divided into cells, each of which is serviced by a base station or Mobile Support Station. This MSS provides a connection endpoint for the roaming mobile. The MSSs are all connected to the Internet. Thus, a user in a cell receives data via ....
