    Development of internet of flying things (lot) simulator
    (Université Larbi Ben M'hidi Oum El Bouaghi, 2022) Benghalia, Amira; Berkou, Samiya; Zaidi, Sofiane
    Unmanned Aerial Vehicles (UAVs) have recently received significant attention by the civilian and military community, mostly due to the fast growth of UAV technologies supported by wireless communications and networking. UAVs can be used to improve the efficiency and performance of the Internet of Things (IoT) in terms of connectivity, coverage, reliability, stability, etc. In particular, to support IoT applications in an efficient manner, UAVs should be organized as a Flying Ad-hoc NETwork (FANET). FANET is a subclass of Mobile Ad-hoc Network (MANET) where nodes are UAVs. Internet of Flying Things (IoFT) is the integration of IoT with FANET that provides many benefits in terms of: connectivity and coverage, reliability, data processing and storage, real-time services, resistance to weather conditions, and energy supply of IoT nodes. In the scientific research literature, there are any simulator dedicated to the IoFT, for this reason, our work aims to develop an IoFT simulator that allows a collection of UAVs to collect various environmental parameters, such as: temperature, pressure, etc. Furthermore, the simulator provides for the UAV to forward their collected data towards the IoT servers using IoT devices.

    Evaluation and comparison between routing protocols for video streaming in Vehicular
    (Univérsité Oum El Bouaghi, 2020) Ogab, Mostafa; Zaidi, Sofiane
    Video streaming is one of the challenging issues in Vehicular Ad-Hoc Networks (VANETs) due to strict Quality of Service (QoS) and Quality of Experience (QoE) requirements of the video transmission, such as delivery ratio, transmission delay and mean opinion Score (MOS). Furthermore, video streaming is affected by VANET features, such as the high dynamic topology, fluctuation of vehicle density, and environmental obstacles. In VANET, video streaming can be achieved by using different VANET communication types, such as V2V (Vehicle To Vehicle), V2I (Vehicle To Infrastructure), and V2X (Vehicle To Everything). Based on these communications, the vehicles can exchange between them the video stream in a single or multi-hop manner. In VANET, the vehicles applied a routing protocol in order to disseminate the video stream through a path (s) between the sender and the receiver (s) vehicles. In this study, we have reviewed and discussed several studies on routing protocols for video streaming in VANET. An overview of popular existing routing protocols, such as AODV, AOMDV, DSR, DSDV was presented. Furthermore, we have evaluated and compared these protocols in terms of routing performance, such as E2EDelay, throughput, and PDR based on vehicle density in order to judge which one is outperforming in video streaming over VANETs. The simulation results show that the AODV routing protocol is better than AOMDV, DSR, and DSDV in terms of throughput and End-to-End delay but unstable in PDR. In general, the significance of these results is that the reactive routing protocols AODV, AOMDV, and DSR are more effective than the proactive routing protocol DSDV, in reverse the latter is more stable than the other ones.

    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 of data transmission in a fanet network
    (University of Oum El Bouaghi, 2024) Boucetta, Anouar; Zaidi, Sofiane
    Communication is one of the most significant design issues for multi-UAV (Unmanned Aerial Vehicle) systems, as it is essential for UAVs' cooperation and collaboration. The infrastructure can facilitate communication between UAVs if each one is directly linked to it, such as through a satellite or a ground station. However, the capabilities of multi-UAV systems are limited by this infrastructure-based communication design. The issues arising from entirely infrastructure-based UAV networks can be resolved by ad hoc networking between UAVs. FANETs have emerged as a viable option for a variety of unmanned aerial system applications. For instance, FANETs might be utilized for search and rescue operations or urban monitoring. These networks, however, have unique communication issues along with a wide range of specialized features. Consequently, many research projects use network simulation to examine their performance. Simulating data transmission via the FANET network is the aim of our work. In particular, this work starts with a review of the basics of wireless and ad-hoc networks. Next, we explore FANETs, including their architecture, characteristics, design considerations, communication, applications, and routing protocols. Furthermore, we describe the simulation approaches, focusing on the NS-2 simulator for data transmission modeling in FANETs, and includes Ubuntu installation (dual boot with Windows 10). Lastly, we go into great length about the suggested data transmission paradigm in FANETs, including its design, implementation, and performance assessment .

    Study of the effect of queue size in flying ad hoc networks ( FANETs)
    (Université d'Oum El Bouaghi, 2023) Bazaz, Bahaeddine; Meziani, Salah Eddine Amine; Zaidi, Sofiane
    applications, such as: recognition, surveillance, search and rescue operations, and data transmission. FANET consisted of a group of autonomous Unmanned Aerial Vehicles (UAVs) that communicate with each other to form a self-organizing network. This network can be operated only or with traditional communication infrastructure. Many advantages can be offered by Flying Ad-Hoc Networks (FANETs) are an emerging field with significant potential for various FANET, such as: scalability, mobility, low cost of deployment and maintenance, increased flexibility in terms of network metrics which makes them ideal for applications that require rapid deployment and reconfiguration. However, the performance of FANET is related to UAV queue size which have a significant impact on data transmission quality. In this project, we have reviewed and discussed several studies at Mac layer level in FANET which ensure efficient and fair transmission of data. an overview was provided of MAC layer queue and algorithms which used to manage the data transmission. Moreover, we have provided our proposed conceptual model of the queue size effect on data transmission in FANET. Furthermore, we have evaluated the network performances in function of queue size in terms of various metrics, such as: delay, throughput, and Packet Delivery Ratio (PDR).The simulation results using NS2 show that when the queue size is too small, the throughput and PDR decreased due to congestion problem, and the delay increased. On the other hand, when the queue size is too large, the delay increased and the throughput and PDR increased. In resume, the results of this project showed that the change of queue size can affect significatively the data transmission quality in FANET
