Article
Multimedia Broadcast Multicast Service system supports efficient diffusion of multicast multimedia services in cellular networks. Our previous work shows that the radio resource management problem for MBMS can be modeled as a combinatorial optimization problem which tries to find optimal assignment of power and channel codes [1]. In this paper, we...

Multimedia Broadcast Multicast Service (MBMS) system supports efficient diffusion of multicast multimedia services in cellular networks. Our previous work shows that the radio resource management (RRM) problem for MBMS can be modeled as an optimization problem which tries to find optimum assignment solution of power and channel codes in a given sea...
Article
This paper aims to solve the Radio Resource Management (RRM) problem for Multimedia Broadcast Multicast Service (MBMS) system in cellular network. We develop a flexible model to perform dynamic radio resource allocation for MBMS service by using metaheuristic approach. We conduct fitness landscape analysis to study the characteristics of the propos...
Conference Paper
In this paper we present a mathematical modeling of Radio Resource Management (RRM) for multicast service diffusion based on Multimedia Broadcast Multicast Service (MBMS) standard. In this model, a flexible allocation approach named F2R2M is proposed, combining three candidate transport channels with scalable video transmission technology. The allo...
Conference Paper
The success of an electric vehicle Fleet operation, engaged in vehicle-to-grid (V2G) depends largely upon the reliable ICT technology that guarantees deterministic data transfer between the fleet aggregator, vehicles and other actors. In this paper, we present a prototype ICT architecture and simulator for Fleet based V2G operation. The prototype i...

With the spreading of Wi-Fi networks, new services are provided. In particular, Wi-Fi networks can be used to locate mobile terminals based on measurements. In this paper, we propose a hybrid positioning model based on signal strength measurements and a probabilistic positioning system based on pre-computed signal strength map. Both models are test...
Conference Paper
Full-text available
In urbanized and indoor environments, outdoor positioning systems, such as Global Navigation Satellite Systems (GNSSs), are often inaccurate and adaptations of such systems to those contexts are expensive and hard to deploy. Nowadays, a lot of indoor positioning techniques have been studied, but it it quite difficult to objectively evaluate and com...
Article
If outdoor positioning is widely treated and quite precise, positioning indoors or, more generally, in heterogeneous environments, as well as mobility prediction, requires important devices. New wireless technologies (e.g., Wi-Fi, Ultra Wide Band) combine the mobility of terminals with large bandwidth. Terminal mobility is one of the major pillars...
Conference Paper
Wireless network positioning is the main pillar of the continuity of rich and mobile multimedia applications. Good position accuracy is particularly difficult to obtain in urban or leafy areas and indoors or in mixed (both indoor and outdoor) environments. A system proposing such positioning must localize any mobile terminal accurately within hosti...
Article
Democratization of mobile terminals and bandwidth capability allow to consider new applications, particularly context-aware applications. Such applications require service continuity and mobile terminal positioning. We propose on one hand to locate mobile terminaux and, on the other hand, mobility prediction. Navigation Satellites Systems are not...

The spreading of the WiFi networks allows new applications. New problems bound to the mobility of the terminals arise. In this article, we deal with the requirements and the solutions to address the service continuity in mobility. These requirements are integrated in mobility management middleware. It requires terminal positioning. The solution pro...
Conference Paper

If outdoor positioning is widely treated and quite precise, indoor or more generally in heterogeneous environment, the positioning (and also mobility prediction) requires consequent devices. The WiFi solution, easy to deploy and cheaper, becomes today an alternative. Our refinement approach, which is based on, both a friis calibrated model and the...
Conference Paper
The spreading of the WiFi networks allows new applications. New problems bound to the mobility of the terminals arise. This article addresses the service continuity in mobility which requires terminal positioning. The solution proposed is iterative trilateration for which the distances are computed according to the signal strength. This solution is...

With the massive arrival of wireless networks, the mobility of the terminals increases with the interconnec-tions. New problems, such as mobile multimedia content streaming, arise with the emergence of new mobile mul-timedia services. In this paper, we present a mobility model adapted to the logging of mobile positioning or the tracking of mobiles....

Two types of applications use indoor positioning, services linked with mobility, such as guided tour or meeting systems, and the active security of a wireless network which locates intrusive unauthorized mobile terminals. Indoor positioning cannot be managed by a geostationary system like GPS. In fact, current researches are being conducted to conc...

Résumé—Le géopositionnement dans les réseaux sans fil est le premier verrou à ouvrir pour permettre une continuité des applications multimédias riches en mobilité, au sein de zones bâties, en intérieur comme en extérieur. Il est donc nécessaire d'être capable de bien se localiser au sein d'environnements hostiles, tout particulièrement à l'intérieu...

La démocratisation des terminaux mobiles et l'accroissement des débits disponibles permettent d'envisager de nouvelles applications, en particulier relatives au contextes. Celles-ci nécessitent d'assurer la continuité des services et la détection de la position du terminal mobile. Nous proposons d'une part la géolocalisation des terminaux et, d'aut...
