Satellites are becoming increasingly software dependent. Due to the growth in computer hardware performance and the increasing complexity of space missions, On-Board Software (OBSW) plays nowadays a relevant role in implementing complex system-level requirements. In addition to this, stakeholders need to have preliminary OBSW versions to support satellite integration, testing, and validation activities...
Global software development (GSD) is in a booming stage from the last decade with the advances in information and communication technologies (ICTs). Despite of the benefits gained from GSD, the developer organizations still face a lot of difficulties in integrating the software components, developed by various GSD teams, into a final product. In our previous study we identified a list of nine critical...
Deep learning is a sub-set of machine learning practice employing models based on various learning network architectures and algorithms in the field of artificial intelligence. Businesses planning to adopt a deep learning solution should comprehend a set of complex choices in hardware, software, configuration and optimizations to setup a functional deep learning solution. This paper will describe...
In this paper we propose to consider a study aimed at improving the Honeypot system performance. There is observed architecture of the designed service of collecting and updating common database of exploits, which is necessary for this study, necessary for building and further Honeypot system maintenance. The data obtained using this service are analyzed in order to determine the free server software...
Small unmanned aircraft are being used in an increasing number of applications requiring cooperation between multiple heterogeneous vehicles. Multi-agent control algorithms can be implemented to control such systems but often require an underlying communications framework with integrated payloads. This paper presents a modular heterogeneous multi-agent control framework with payload integration. This...
Software Defined Network (SDN) is an advanced approach to designing dynamic, manageable, cost-effective, and adaptable network architectures. SDN will play a key role as an enabler for 5G and future networks. Transferring network monitoring functions to a software entity working in conjunction with configurable hardware accelerators through a scheme called Software Defined Monitoring (SDM) is one...
An Unmanned Aircraft System (UAS) is a Cyber- Physical System (CPS) in which a host of real-time computational tasks contending for shared resources must be cooperatively managed to provide actuation input for control of the locomotion necessary to obtain mission objectives. Traditionally, control of the UAS is designed assuming a fixed, high sampling rate in order to maintain reliable performance...
The significant increase in the ubiquity and connectivity of computing devices has opened new possibilities for addressing social and environmental challenges, e.g., ambient assisted living, smart city infrastructures, emergency coordination, environmental monitoring. Engineering such systems commonly called smart Cyber-Physical Systems (sCPS) is typically very challenging because of their inherent...
In this paper, a reconfigurable component based on the new platform is designed for the intercommunication between different communication devices and the difficulty of software and hardware upgrade with the purpose of improving the portability and sharing of components. According to the development process of reconfigurable components and the key technology of reconfigurable components in GNU Radio...
This paper presents a System-on-Chip approach (SoC), exploiting the availability and capacity of SRAM-based FPGA technology to design and implement an on-board computer system (OBC) for use in low earth orbit (LEO) nano-satellite. This work is part of a University project that aims to develop the first Moroccan university nano-satellite based on the “CubeSat” standard. As such, the proposed OBC is...
Software Defined Networking (SDN) enables network innovation and brings flexibility by separation of the control and data planes and logically centralized control. However, this network paradigm complicates flow rule management. Current approaches generally install rules reactively after table misses or pre-installs them by flow prediction. Such approaches consume nontrivial network resources during...
FPGA development can be time-consuming. Tools to simplify and accelerate development include frameworks, which allow developers to focus on their core problems, and provide pre-built solutions for recurring problems. RF Network-on-chip (RFNoC) is such a framework. It allows developers to integrate existing IP into more complex systems, involving both software and FPGA components, with little overhead...
Internet-native audio-visual services are witnessing rapid development. Among these services, object-based audiovisual services are gaining importance. In 2014, we established the Software Defined Media (sDM) consortium to target new research areas and markets involving object-based digital media and Internet-by-design audio-visual environments. In this paper, we introduce the SDM architecture that...
Requirements of mobile apps are often hard to elicit from massive numbers of users, although it is important for the solution architecture to meet them. Mobile Twin Peaks approach is proposed as a process of developing apps concurrently and iteratively that incorporates bidirectional communications within a mobile app. The communications allow both requirements engineers and software architects to...
The current developments of software defined networking (SDN) paradigm provide a flexible architecture for network control and management, in the cost of deploying new hardwares by replacing the existing routing infrastructure. Further, the centralized controller architecture of SDN makes the network prone to single point failure and creates performance bottleneck. To avoid these issues and to support...
The paper presents the software concept of a data acquisition system used in vegetation status monitoring. The work focuses on finding a robust, adaptable and appropriate software architecture that can be used as a standard in the data capturing process in precision agriculture. A solution is proposed that provides a high degree of modularity and expandability, error management capabilities, a database...
In the LTE EPC, many network entities and interfaces have to be maintained and updated regularly. Moreover, to accommodate more users, new hardware must be integrated, although rarely used. To address these challenges, the EPC can be moved to the cloud using two modern technologies: SDN and NFV. In this paper, we study the impact of integrating these novel technologies on LTE networks. We propose...
In recent years, several important initiatives have appeared worldwide, aimed at bringing significant innovation in industrial networked systems (INSs). As an example, the Industry 4.0 and Factory of the Future frameworks are paving the way to modern intelligent factories, where issues such as the communication complexity between smart devices and system on-the-fly reconfiguration are dealt with in...
