abstract = {In general IP multicast supports location-independent addressing and routing for a group of hosts. This ability is similar to the requirement for mobility support in IP-based networks though in a different context. MOMBASA stands for ``MObility support – a Multicast BASed Approach''. It is intended to utilise multicast in order to support network level mobility. The basic mechanism of a multicast-based handover can be composed of a multicast join- and leave-operation of the new and old multicast router, respectively. Additionally to the basic mechanism, MOMBASA investigates extended multicast functionalities which improves the handover in terms of the handover latency, the management of the multicast group and adaptation of the multicast data traffic to the wireless transmission capabilities. In particular the extended multicast functionalities are useful for vertical handover. Unfortunately today's IP multicast suffers from scalability problems and is not generally available. Nevertheless it is commonly expected that the future Internet will provide an optimised multicast. MOMBASA works out the requirements of handover on future multicast protocols and investigates alternate IP-style multicast protocols. As a first approach a multicast protocol is considered which realises a dynamic multipoint-to-multipoint communication in switched networks. An experimental handover testbed is set up which proofs the basic approach and provides extended multicast functionalities. The testbed is described and performance results are given. Other IP-style multicast protocol will be investigated in further steps.},

abstract = {The rerouting of connections for handover in a broadband mobile cellular network is investigated. We address networks with a connection-oriented backbone, which supports quality-of-service (QoS). Moreover it is assumed an IP-style multicast on top of the connection-oriented network. We advocate to utilize the IP-style multicast in order to reroute connections for handover. Three rerouting schemes are proposed, which are based on the IP-style multicast. One of the schemes realizes a predictive approach, where a call is pre-established to potential new base stations by setting up a multicast tree with neighboring base stations as leaf nodes. This approach reduces the handover latency caused by rerouting to an absolute minimum and improves communication with strict time constraints and frequent handover. For experimental investigations of the rerouting schemes a testbed is set up, which is based on an open, non-proprietary, experimental networking environment. Its signaling software offers a direct many-to-many communication, rather than requiring one-to-many overlays and the switching hardware supports scalable and efficient multicast by cell-recycling. The testbed is performance evaluation of the rerouting scheme.},
