چکیده

Dans cet article, nous détaillons et étudions TAPIOCA (distribuTed and AdaPtive IntersectiOns Control Algorithm), un algorithme distribué qui défini les séquences et durées des feux verts dans un système de transport intelligent. TAPIOCA s’appuie sur les données recueillies par un réseau de capteurs sans fil déployé aux intersections afin de décider localement de son programme. TAPIOCA ne se reposant pas sur une entité centrale, il est réactif et facile à installer. Nous exposons tout d’abord une version simple intersection de TAPIOCA, qui a pour but d’améliorer la longueur des files d’attente et la probabilité de famine. Nous étendons ensuite TAPIOCA au cas des multiples intersections en définissant des mécanismes facilitant la circulation entre intersections proches afin de créer des vagues vertes. Les algorithmes sont évalués à l’aide du simulateur SUMO par le biais de trois scénarios: données réelles issues de la ville d’Amiens, le projet TAPASCologne et une grille d’intersections. Les résultats montrent que TAPIOCA génère un temps moyen d’attente inférieur à d’autres stratégies, adaptatives ou non.

Target Tracking with Unknown Maneuvers Using Adaptive Parameter Estimation in Wireless Sensor Networks

Abstract- Tracking a target which is sensed by a collection of randomly deployed, limited-capacity, and short-ranged sensors is a tricky problem and, yet applicable to the empirical world. In this paper, this challenge has been addressed a by introducing a nested algorithm to track a maneuvering target entering the sensor field. In the proposed nested algorithm, different modules are to fulfill...
