Context-awareness in IoT applications is an emerging research field with profound impact on smartness, relevance, adaptability, dependability and flexibility of such applications. Relatively few substantial R&D projects have been carried out on how IoT-scale context can be stored, indexed, retrieved and provisioned to various IoT services. This paper addresses the challenge of building IoT context...
This paper presents the design of a coprocessor that performs data sorting for min/max queues in real-time systems. Sorting architecture is based on systolic array architecture and heapsort algorithm. The proposed architecture, called Rocket Queue, is able not only to sort all items according to their sort values, but it is also possible to remove any item from the structure according to its unique...
Dense Small Cell networks are considered the most effective way to cope with the exponential increase in mobile traffic demand expected for the upcoming years and are one of the foundations of the future 5G. However, novel architectures are required to enable cost-efficient deployments of very dense outdoor Small Cell networks, complementing the coverage layer provided by macro-cells. In this regard,...
Today's systems or devices in the Internet of Things (IoT) applications are more and more complex. Analytic facilities are typically deployed in these systems for Prognostics and Health Management (PHM) purposes. One of the main challenges for architecting such control and diagnostics systems is their restrictive performance requirements, which directly impact the architecture and subsequent detailed...
The authors based their Research and Development Project (RDP) on a mixed research method that is mainly based on intelligent neural networks and action research reasoning approach; where both methods are very similar and resemble to the human brain structure and its way of functioning. The applied research method is founded on a real life case for detecting and processing heuristic algorithms for...
The Internet-of-Things (IoT) is unanimously identified as one of the main pillars of future smart scenarios. However, despite the growing number of IoT deployments, the majority of IoT applications tend to be self-contained, thereby forming vertical silos. Indeed, the ability to combine and synthesize data streams and services from diverse IoT platforms and testbeds, holds the promise to increase...
The journey towards the deployment of next generation networks has recently accelerated, driven by the joint effort of research and standards organisations. Some key innovative design concepts have been recently consolidating and are going to characterise the notable discontinuity between 4G and 5G systems. Among those, Architecture Modularisation, discussed in this paper, is regarded by the authors...
This paper presents an overview of the architecture of an internetworked self-driving car system-of-systems. The architecture considers both the car as a system-of-systems as well as multiple cars participation in a larger multi-vehicle system-of-systems. Each relevant aspect of the architecture is reviewed.
Tight coupling of business and the software implementation is the biggest difficulty of designing software system architecture. The business change will inevitably lead to software restructuring, which is the necessary result of business-driven development, and it greatly restrict the development of software productivity. Metadata driven design, as an architecture pattern, can effectively reduce the...
The allpass filter, since inception in the 1960s, has found its way into a wide range of digital signal processing applications. The structure of the filter also lends itself to robust analog lattice implementations using traditional passive electronic components. In the late 2000s, the versatility of the allpass translated into the photonic domain since it can be easily realized using a variety of...
Delay tolerant networks have already evolved as a pragmatic solution to various requirements such as delayed routing in wireless networks. They can also be used in place of traditional wireless networks in the border areas or highly sensitive areas, thus contributing to the data security in such places. In this paper, a border security architecture has been proposed where DTN is used for transferring...
Modeling IoT systems behaviors and architectures requires new approaches to be elaborated for handling the challenging issues such as: large scale interaction and real-time reconfiguration. This can help both during the design and the operation steps for ensuring a correct design and for delivering a performant service. Different studies have been recently conducted and new initiatives, at the national,...
Storing data in the cloud is often a long and disputed process of ensuring that cloud service providers meet the clients minimum requirements. Often, this process can be costly, lack adequate results, and miss important security checks that are often overlooked. Therefore, I propose a new strategy for meeting cloud security requirements through using a dynamic parsing agent to encrypt outgoing data...
In its initial part, the paper presents an overview of popular technologies and systems currently developed or employed in maritime communication. These solutions are used to provide both ship-to-ship and ship-to-shore communication for the purpose of supporting specific services, often dedicated to maritime safety and e-navigation. Utility of such communication systems have been thoroughly verified...
The internet of things is an evolving trend, connecting "things" to the internet, exchanging and collecting information about the surrounding environment. This is possible, by using different devices such as sensors and actuators feeding information that when connected together, enable to monitor and interact with the surrounding environment. Nowadays, there are many devices with different...
The Cyber-Physical System (CPS) is the core concept of Industry 4.0 for building smart factories. We can rely on the ISA-95 architecture or the 5C architecture to build the CPS. However, both architectures emphasize more on vertical integration, and less on horizontal integration. This paper proposes the 8C architecture by adding 3C facets into the 5C architecture. The 3C facets are coalition, customer,...
Fifth Generation (5G) telecommunication system is going to deliver a flexible radio access network (RAN). Security functions such as authorization, authentication and accounting (AAA) are expected to be distributed from central clouds to edge clouds. We propose a novel architectural security solution that applies to 5G networks. It is called Trust Zone (TZ) that is designed as an enhancement of the...
Component-oriented programming languages(COPLs) bridge the gap between architecture descriptionlanguages (ADLs) and general purpose programming languages. COPLs emphasize designing software systems out of reusablecomponents which are connected by communication ports. These ports facilitate the design of highly modular softwarearchitecture. The flexibility of a component-based system, however, is partly...
Self-healing is an increasingly popular approach to ensure resiliency, that is, a proper adaptation to failures and attacks, in cyber-physical systems (CPS). A very promising way of achieving self-healing is through structural adaptation (SHSA), by adding and removing components, or even by changing their interaction, at runtime. SHSA has to be enabled and supported by the underlying platform, in...
As building structure is more and more complex, confronting evacuation prone to retrograde and blockage phenomenon, traditional plain of evacuation schematic has been difficult to meet the demand guidance for fire evacuation. In this paper, we propose a building information model (BIM) for the guidance of the three-dimensional building within the evacuation path. Full integration of BIM Technology...
