The trend towards the digitalization of our homes is motivated by the development of hardware and software platforms that have been researched in recent years. As in the Internet of Things, building a single, global platform that enables communication with a myriad of devices for home automation is virtually impossible. The platform proposed in this work deals, in isolation, with the problems in each...
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...
Synchrophasor technology has numerous applications ranging from simple grid monitoring/visualization to real-time protection and control. Most legacy phasor measurement units (PMUs) and phasor data concentrators (PDCs) deployed in power grids support the IEEE C37.118.2 communication framework, which is highly vulnerable to cyber attacks due to lack of inherent security mechanisms. The IEC 61850-90-5...
The relevance of cross border security operations has been identified as a priority at European level for a long time. A European network where Public Protection and Disaster Relief (PPDR) forces share communications processes and a legal framework would greatly enforce response to disaster recovery and security against crime. Nevertheless, uncertainty on costs, timescale and functionalities have...
The European Council has been stressing the need for interoperability among technologies used for Public Protection and Disaster Relief (PPDR) communications across Europe for a long time. Nevertheless, while the introduction of TETRA and TETRAPOL technologies in the last two decades has increased the possibility to talk cross agency internally in a country, cross border communication for the public...
Machine-to-Machine (M2M) paradigm is one of the main concern of Internet of Things (IoT). Its scope is to interconnect billions of heterogeneous devices able to interact in various application domains. Since M2M suffers from a high vertical fragmentation of current M2M markets and lacks of standards, the European Telecommunications Standards Institute (ETSI) released a set of specifications for a...
The paper presents requirements related to a heterogeneous interoperable and transportable gateway called HitGW that is designated to connect different incompatible communication systems used by First-Responders (FRs) and to make them interoperable with IP-based networks. The HitGW allows IMS type of services and applications over a broadband network composed of ordinary Public Protection and Disaster...
Internet of Things (IoT) is seen as the future of Internet. We will step out from typical current communication paradigm, to a much wider spectrum, where normal “things” will talk to each other, independent of human interaction. Emphasizing its importance in health industry, it can save lives and improve the ageing and disabled population's quality of living. It is not just things connected to the...
Internet of Things (IoT) domain has attracted a lot of interest over the last few years, to a large extent due to its applicability across a plethora of application domains. This variety of application domains resulted in a variety of requirements that IoT systems should comply with. Due to the heterogeneity of the domains, the requirements varied significantly, and demanding more or less complex...
Optimization of energy consumption in future intelligent energy networks (or Smart Grids) will be based on grid-integrated near-real-time communications between various grid elements in generation, transmission, distribution and loads. This paper discusses some of the challenges and opportunities of communications research in the areas of smart grid and smart metering. In particular, we focus on some...
Reconfigurable Radio Systems (RRS), based on Software Defined Radio (SDR) and Mobile Ad-hoc Network (MANET) technologies, offer considerable advantages for military operations, such as increased network survivability and interoperability. The RRS-based Common Tactical Radio System (GTRS), currently in development by the Swedish Armed Forces, is designed for use in diverse geographical settings and...
The integration of cloud and grid infrastructures is still of current interest, because it provides a way for the scientific area to ensure sustainability of well engineered grid applications. The integration of well established grid infrastructures with cloud systems also fosters their complementary usage, simplified migration of applications, as well as efficient resource utilization. In this paper,...
SOA have been deployed as a mean to offer a better flexibility, to increase efficiency through reuse of services and also to improve interoperability by providing new opportunities to connect heterogeneous platforms. However, those benefits make security more difficult to control. Fortunately, new standards are proposed to treat this issue, but their current use makes the architecture much more complex...
Mobile commerce (m-commerce) has dramatically changed our lives, while it has also posed challenges for individuals and businesses. One of the big concerns of m-commerce is security. In addition to the security issues of wired Internet, there are some special security demands for doing business over the wireless Internet, due to the limitations of wireless networks and mobile devices. This paper first...
High energy physics (HEP) experiments are facing unprecedented challenges to deal with huge volumes of data. Grid is the excellent technology for it. However, Incompatibility of a variety of grid middewares is an obstacle to exploit the resources on multiple grid infrastructures. This paper firstly introduces HEP experiments and HEP grid, and then reviews the solutions for grid interoperability and...
E-business and e-government implementations are becoming more and more widespread with growing number users depending on availability, accuracy and security of such e-services. The users must be able to trust these services, otherwise they will be reluctant to embrace the new opportunities and will not be able to reap the potential benefits. In addition, the end users wish to use the e-services in...
