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)
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)
Cette étude est dédiée aux expérimentations de simulations sur les aspects de la qualité de services (QoS), dans le processus de transfert de flux multimédia par un protocole complexe de transport (XTP). Une introduction dans le domaine est donnée en définissant les concepts principaux : activités, dimensions et catégories ainsi que les mécanismes et les(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)
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)
