—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)
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)

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)
— In this paper, we extend the differentiated deployment method which we have proposed in [1] by adding the connectivity constraint. We assume a fixed communication ray and a probabilistic detection model. We also consider that to each point in the deployment area is associated a detection probability threshold, which must be satisfied by our deployment(More)
