Cyber-Physical Systems (CPSs) may fail during runtime on supporting decision making if they are not capable of detecting and correcting their own failures. Thus, it has been proposed that CPSs should be self-aware, context-aware and goal-aware. In this paper we present preliminary results about how an architecture built over the Extensible Messaging and Presence Protocol (XMPP) may implement a distributed...
One of the popular concepts nowadays is the Internet of Things (IoT). IoT will convert our daily life objects into smart objects. In order to become a part of the IoT network, these smart devices will require some technologies and protocols. In this paper, we will study the different te chnologies that enable the smart objects to be come a part of the IoT network. Furthermore, we will have a look...
In the past, virtualisation, and with it the move toward the cloud, has had a strong influence on the ICT (Information Communication Technology) sector, and now seems set to revolutionise the telecommunications sector as well. The virtualisation into software artefacts of functions that would usually be deployed as hardware has come to be known as Network Function Virtualisation (NFV), and the European...
Software-defined networking (SDN) overcomes many limitations of traditional networking architectures because of its programmable and flexible nature. Security applications, for instance, can dynamically reprogram a network to respond to ongoing threats in real time. However, the same flexibility also creates risk, since it can be used against the network. Current SDN architectures potentially allow...
It is the aim of IoT-Testware to supply a rich set of TTCN-3 test suites and test cases for IoT technologies to enable developers in setting up a comprehensive test environment of their own, if needed from the beginning of a project. Initially, IoT-Testware will focus on protocols like CoAP and MQTT. To ensure test and implementation technology independence, the test suites will be realized in TTCN-3...
The rapid development of technology nowadays led people to a new and revolutionary concept, named the Internet of Things. This model imposes that all "objects", such as personal objects (smartphones, notebooks, smart watches, tablets etc), electronic equipment embed with sensors and other environmental elements are always connected to a common network. Therefore, one can access any resource...
The incredible rapid development of internet technologies, primarily thanks to omnipresent access of high speed broadband internet access and supporting technologies like Big Data, Cloud Computing, REST/Web services as well as cheap electronic equipment that use new wireless communications standards, lead to equal rapid growth of number of smart devices - “things” - connected to the internet. Increased...
Today's military platforms are equipped with variety of sensors and effectors. However, these components are rarely interconnected or are only linked via manufacturer-specific, proprietary interfaces. This hinders changes to and extensions of platform components. Often platform modifications are only possible with the help of the original integrator, which complicates a seamless integration of new...
In vehicular communication protocol stacks, received messages may not always be decoded successfully due to the complexity of the decoding functions, the uncertainty of the communication load and the limited computation resources. Even worse, an improper implementation of the protocol stack may cause an unfair data age distribution among all the communicating vehicles (the receiving bias problem)...
Over the previous years, many service-oriented (SO) solutions have been proposed by European research projects for the technological advancement of industrial systems. These projects typically include a software reference architecture (RA) based on the concepts of service-oriented architectures (SOA) and, often-times, an accompanying technology stack to guarantee system-wide interoperability. In this...
Software Defined Networking (SDN) has become a popular paradigm for centralized control in many modern networking scenarios such as data centers and cloud. For large data centers hosting many hundreds of thousands of servers, there are few thousands of switches that need to be managed in a centralized fashion, which cannot be done using a single controller node. Previous works have proposed distributed...
Internet of Things (IoT) encompasses numerous old and new technologies under its umbrella; which means there is a huge diversity in types of devices, protocols and mechanisms that are to be supported. Things by themselves need to inter-network and collaborate to provide the necessary level of service expected out of them, working in isolation does not help in many cases. Interoperability issues have...
The Internet of Things has been widely deployed in various areas of daily life through heterogeneous communications protocols. Each unstandardized protocol focuses on a specific IoT communication pattern. Inspired by the Internet architecture over which divergent devices can easily be accessed and a considerable number of applications can be run, we propose a generic architecture for IoT. This architecture...
We present the architecture and partial proof of concept implementation of distributed responder ARP (DR-ARP), a software defined networking (SDN) enabled enhancement of the standard address resolution protocol (ARP). It is intended to improve network security and performance by exerting much greater control over how ARP traffic flows through the network as well as over what actually delivers the...
Nowadays, Near Field Communication (NFC) technology is being experimented for payment systems to perform purchase transactions without physical contact, without entering a PIN code or a signature. An NFC purchase transaction is mainly executed between a client's payment device (NFC bank card or NFC smartphone) and a merchant's payment device. The latter may be either an NFC point of sale machine for...
Heterogeneity in constrained networks and gateways is perhaps one of the single greatest challenges facing end-to-end management of devices and networks in the IoT. Today, the Lightweight M2M (LWM2M) protocol, leveraged on open Internet standards, has become a strong contender for REST-based IoT management. However, significant challenges exist for remote gateway management, particularly for proxies...
Smart meters are at high risk to be an attack target or to be used as an attacking means of malicious users because they are placed at the closest location to users in the smart gridbased infrastructure. At present, Korea is proceeding with 'Smart Grid Advanced Metering Infrastructure (AMI) Construction Project', and has selected Device Language Message Specification/ COmpanion Specification for Energy...
Software Defined Networking (SDN) is an emerging networking paradigm that greatly simplifies network management tasks. In addition, it opens the door for network innovation through a programmable flexible interface controlling the behavior of the entire network. In the opposite side, for decades traditional IP networks were very hard to manage, error prone and hard to introduce new functionalities...
The Internet of Things (IoT) enables the connections of billions of devices to the Internet. It is thus very important to effectively manage this huge amount of devices. Among many available device management protocols, Open Mobile Alliance Lightweight M2M (OMA LWM2M) has been adopted by the global M2M standards, ETSI M2M and oneM2M as the standard for device management. However, OMA LWM2M-supported...
To satisfy more and more complicated requirements on information recording, processing, exchange etc. in newly developed intelligent satellites, a distributed storage system is designed based on SpaceWire network in satellite platform. In this distributed storage system, a SpaceWire router unit serving as the core device of star network connects several nodes, including onboard computers, namely,...
