One of the biggest challenges of the Internet Service Provider actually is the ability to deploy dynamically new services. For this purpose, in this paper, we are interested in the specification and modeling of different notions in the context of autonomic networks, in order to dynamically deploy new network services. Thus, we propose in this work a new(More)
In this paper, we address the Wireless Sensor Network (WSN) deployment issue. We assume that the observed area is characterized by the geographical irregularity of the sensed events. Formally, we consider that each point in the deployment area is associated a differentiated detection probability threshold, which must be satisfied by our deployment method.(More)
—With the recent evolution of network-based mul-tiplayer games and the increasing popularity of online games demanding strict real-time interaction among players – like First Person Shooter (FPS) –, game providers face the problem to correlate network conditions with quality of gaming experience. This paper addresses the problem of the estimation gameplay(More)

Taking into consideration the popularity of multiplayer games and the tremendous success of wireless networks, we strongly believe that future game engines will benefit from the integration of MANET (Mobile Ad hoc NETworks) technology [1]. Indeed, in addition to the social interests of playing with close located persons, MANET technology will allow players,(More)
The objective of this work is to propose an architectural solution to achieve an efficient, distributed control and management of DiffServ enabled networks. DiffServ offers a scalable QoS provisioning solution but it introduces a certain amount of complexity in terms of management and control. The proposed solution is an alternative to the client/server(More)
The aim of the Active Networking today effort is to design, develop and implement new communication architectures that allow rapid, safe and dependable creation, reconfiguration, and deployment of advanced networking services, protocols and management components. The Active Networking paradigm achieves this goal through the concepts of (1) self-directing(More)
In this paper we propose a new content-aware ARQ scheme for H.264 video streaming over UMTS wireless links. We propose a new scheme which assesses the importance of each packet using the FMO (Flexible Macro-block Ordering) tool, a novel error robustness tool of H.264 video encoding standard. Temporal values are then given to video packets in respect to(More)
