This paper provides a view on the developing process of the Media Independent Information Service, later referred as MIIS, described in the IEEE 802.21 standard, which has the main functionality of providing the mobile terminal information about all access points in his coverage area. Our approach is towards the management of the entire mechanism of(More)
-Distributed multimedia applications such as conference and collaborative applications require an appropriate conference management. Close group conferences like meetings, discussions, teleseminars, or consultations need a strictly controlled group membership. Current conference systems achieve this by using a centralized group server as specified in the(More)
In this paper we described the generic design of software interoperability modules for vertical handover in wireless hybrid access networks. The proposed approach conforms to the IEEE 802.21 Media Independent Handover (MIH) standard and fits into our architecture for reconfigurable interoperability of wireless communication systems, RIWCoS. The next step of(More)
In this paper we describe a context-aware reconfigurable system, which implements the IEEE 802.21 Media Independent Handover (MIH) standard for interoperability between wireless hybrid access networks. The proposed approach uses vertical handover prediction algorithms to improve the resource management decisions, through access to our Web Service(More)
During the last years, software applications performing scenarios related to vertical handovers were revealed. However, the great majority of these demonstrators were designed and optimized for multimode notebooks, having a fair amount of processing power. This article aims to describe on how to implement and optimize the main components of the IEEE 802.21(More)
Zusammenfassung: Videokonferenzen gelten als ein wichtiges Mittel für die Gestaltung von kollaborativen Applikationen im Internet. An ihre Nutzung werden große Erwartungen geknüpft und hohe Anforderungen gestellt. Obwohl der Nutzen von Videokonferenzdiensten auf der Hand liegt, ist ihre Nutzung im Vergleich zu anderen Internetdiensten immer noch recht(More)
