The proliferation of networked appliances or dedicated function consumer devices with embedded processors and network connection capabilities is driving the virtual device concept, whereby such appliances can be controlled, monitored, managed, and extended beyond what they were initially designed to do. The dynamic and ad hoc nature of the discovery and composition of such devices and the services...
The heterogeneous wireless access technologies available on mobile terminals can be used by the operators to improve the quality of service offered to the users and to better manage the network resources. To take advantage of these opportunities support for seamless handover between the heterogeneous technologies available at terminal must be introduced. Media Independent Handover (MIH) standard is...
Recent evolution of intelligent vehicles features the large scale emergence and introduction of multimode mobile terminals, with the capability to simultaneously or sequentially attach to conceptually different access networks. To cope with this, they require some abstracted framework for their management and control, especially in the case of intelligent selection between the various heterogeneous...
The IP multimedia subsystem (IMS) could very well be the best solution for most telecom operators. The more recent releases have included interfaces to fixed line networks and wireless LANs. This has consequences both for the migration of the core network as well as the integration of future mobile services and applications. Also, an interworking between IMS providers is considered to be a major step...
With the increasing proliferation of mobile devices with advanced capabilities and coupled with increasing deployments of IMS networks that combine interactive multiparty communications with quality of service features, multimedia conferencing is a service that many end-users will now be able to enjoy. In this paper we propose new techniques to be adapted while initiating a conference in order to...
This contribution addresses the case when live packet-switched video is used to enrich circuit-switched speech calls in mobile telephony. Circuit-switched and packet-switched transmissions generally operate on completely different transmission paths resulting in different QoS in terms of delay and loss rates. In this case, video and audio data recorded at the same time are not multiplexed together...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
Future computer environments will include mobile computers which will eiUler be disconnected, weakly interconnected by low speed wireless networks such as GSM, or fully inter-connected by high speed networks ranging from Ethernet to ATM. While the transition between networks is currently a heavyweight operation we believe that developments in network interface technology will soon enable mobile computers...
