Zusammenfassung

Ein Forschungsschwerpunkt in der Entwicklung von Kommunikationsinfrastrukturen stellt derzeit die Integration von drahtlosen Netzsegmenten in bestehende IP-basierte Festnetze dar. Bestehende Protokolle des Festnetzes berücksichtigen jedoch nur unzureichend die Einflüsse von funkbasierten Übertragungswegen (variierende Verbindungsqualitäten, Möglichkeit des Roamings). Eine effiziente multimediale Datenkommunikation bei Einbeziehung funkbasierter Übertragungswege erfordert Adaptionsfähigkeit auf mehreren Protokollebenen. In diesem Beitrag werden einige der zu berücksichtigenden Umgebungsbedingen auf mehreren Protokollebenen anhand von Experimenten in einem drahtlosem LAN mit Mobile-IP auf der Netzwerkebene identifiziert und Hinweise zur Anpassung von Kommunikationsströmen formuliert.
