    Design and simulation of the Timed Triggered Protocol (TTP) using agents
    (Elsevier, 2013) Zaidi, Sofiane; Boutekkouka, Fateh
    In this paper, we present our agent based approach for design and simulation of the basic services of the Time Triggered Protocol (TTP) for automotive distributed embedded systems such as the startup algorithm, the membership, the messages sending and reception, errors detection and handling. The proposed architecture is modeled as a multi-agent system and implemented in the JADE platform following mainly the so-called O-MaSE methodology. Using JADE, We developed an ontology that provides an automatic interpretation of frame fields

    Evaluation and comparison study of video streaming routing protocols in vehicular ad-hoc networks
    (University of Oum El Bouaghi, 2021-05-25) Zaidi, Sofiane; Ogab, Mostafa; Khamer, Lazhar
    Video streaming is a challenging issue in Vehicular Ad-Hoc Networks (VANETs), due to the strict video streaming Quality of Service (QoS) requirements, such as throughput, delivery ratio, and transmission delay. Moreover, video streaming is influenced by VANET characteristics, such as the high dynamic topology, fluctuation of vehicle density, and environmental obstacles. In VANET, video streaming can be achieved through different VANET communication types, such as Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I), and Vehicle to Broadband cloud (V2B). Based on these communications, the vehicles can exchange between them the video stream over single or multi-hop link. When the video content is delivered over a multi-hop link, the vehicles have to use a routing protocol to disseminate the video stream through a path (s) between the sender (s) end the receiver (s) vehicles. In this paper, we have presented an overview of popular existing routing protocols for video streaming in VANET, such as AODV, AOMDV, DSR, and DSDV. Furthermore, we have evaluated and compared these protocols in terms of some QoS evaluation metrics, such as throughput, packet delivery ratio, and end-to-end delay in function with vehicles density in order to judge which one is outperforming for video streaming in VANET. The simulation results show that the reactive routing protocols (AODV, AOMDV, DSR) provide higher throughput and packet delivery ratio than DSDV proactive routing protocol. However, DSDV achieves lower end-to-end delay than AODV, AOMDV, DSR routing protocols

    Simulation bassé agents des protocoles de communication des systèmes embarqués distribués temps réel pour l'automobile
    (Université d' Oum El Bouaghi, 2014) Zaidi, Sofiane; Boutekkouk, Fateh
    Dans ce mémoire nous présentons notre approche pour la modélisation et la simulation des services de base des protocoles TTP et FlexRay pour les systèmes embarqués distribués temps réel de l'automobile, tels que l'initialisation du cluster, l'appartenance et l'acquittement, la synchronisation d'horloges, l'envoi et la réception des messages, la détection et le traitement d'erreurs pour le protocole TTP, et le processus de réveil des noeuds du cluster, l'initialisation du cluster, la synchronisation d'horloges, l'envoi et la réception des messages dans les segment statique et dynamique pour le protocole FlexRay. Chaque architecture du protocole TTP ou FlexRay proposée est modélisée à l'aide de la méthodologie O-MaSE sous forme d'un système multi-agent et implémentée sous la plateforme Jade. Nous développons une ontologie Jade et un environnement qui offrent une interprétation automatique des différents champs de la trame (TTP et FlexRay) et de simuler les services de base de ces deux protocoles respectivement
