Cooperative Cyber-Physical Systems (Co-CPSs) can be enabled using wireless communication technologies, which in principle should address reliability and safety challenges. Safety for Co-CPS enabled by wireless communication technologies is a crucial aspect and requires new dedicated design approaches. In this paper, we provide an overview of five Co-CPS use cases, as introduced in our SafeCOP EU project, and analyze their safety design requirements. Next, we provide a comprehensive analysis of the main existing wireless communication technologies giving details about the protocols developed within particular standardization bodies. We also investigate to what extent they address the non-functional requirements in terms of safety, security and real time, in the different application domains of each use case. Finally, we discuss general recommendations about the use of different wireless communication technologies showing their potentials in the selected real-world use cases. The discussion is provided under consideration in the 5G standardization process within 3GPP, whose current efforts are inline to current gaps in wireless communications protocols for Co-CPSs including many future use cases.

Cognitive Radio technology is commonly seen as a promise to form the basis of the next largest breakthrough in the development of ubiquitous wireless broadband services. However, the disruptive nature and complexity of this technology raises a host of associated issues, including the open question on reasons for the slow progression of the innovation. This paper reviews different streams of literature on technology evolution to suggest that CR development can be best conceptualized as anticipatory (pre-)standardizing process at an early phase. At the backdrop of the absent obvious leader in CR development, the authors conduct a co-evolutionary analysis of the CR innovation context to reveal a stakeholders’ domain, which is best positioned to lead the further CR development. Finally, the authors conclude that the regulatory domain oversees some of the most crucial enabling factors that may decide the future of CR technology.

Telecom operators and companies ask for graduates with a specific education on the standards of the Institute of Electrical and Electronic Engineers (IEEE) or the 3rd Generation Partnership Project (3GPP), and the University curricula must consider these needs. The standards are written in a technical form, in a language understandable only by experts, and the technical details and algorithms are not often outlined. Therefore, a new educational methodology must be applied because the teachers have to bridge the gap between the basic knowledge (and the poor technical language) of students and the technical specifics of the standards. The paper presents a structured methodology to provide innovative teaching of the wireless standards for the Engineering Master’s degree, according to the Conceive, Design, Implement, and Operate (CDIO) initiative and project based learning. The methodology is organized in three learning phases to understand the standardization process and improve students’ skills to implement standard compliant communications systems. This challenge can be only won with laboratory activities to assist students in understanding wireless standards and with hands-on experiences during the internship period at telecom operators with the vision of a close cooperation between universities and telecom operators. Only in this way can the students achieve a solid background in designing and developing prototypes compliant with wireless communications standards and working skills for their future professional engineering careers. The effectiveness of the adopted educational methodology to provide innovative learning of wireless standards is evaluated by questionnaires filled in online by students and by the achieved skills implemented as confirmed by telecom operators. In this vision, the paper provides decision support to leaders in educational organizations to teach wireless standards effectively.

Wi-Fi technology connects sensor-based things that operate with small batteries, and allows them to access the Internet from anywhere at any time and perform networking. It has become a critical element in many areas of daily life and industry, including smart homes, smart factories, smart grids, and smart cities. The Wi-Fi-based Internet of things is gradually expanding its range of uses from new industries to areas that are intimately connected to people’s lives, safety, and property. Wi-Fi technology has undergone a 20-year standardization process and continues to evolve to improve transmission speeds and service quality. Simultaneously, it has also been strengthening power-saving technology and security technology to improve energy efficiency and security while maintaining backward compatibility with past standards. This study analyzed the security vulnerabilities of the Wi-Fi power-saving mechanism used in smart devices and experimentally proved the feasibility of a battery draining attack (BDA) on commercial smartphones. The results of the experiment showed that when a battery draining attack was performed on power-saving Wi-Fi, 14 times the amount of energy was consumed compared with when a battery draining attack was not performed. This study analyzed the security vulnerabilities of the power-saving mechanism and discusses countermeasures.

The article deals with the implementation of one of the most promising technologies of the 21st century – the permeable sensor networks of the USN. The features, architecture, organization and routing algorithms of sensory networks are described. It is determined that further improvement of the work of such networks requires standardization of the development process and implementation process. USN's Vertical Sensor Networks is one of the most promising technologies of the 21st century. Cheap and "smart" sensors, in large quantities combined into a wireless network connected to the public communications network, today provide an unprecedentedly wide range of control and management services for buildings, businesses, cars, and so forth. USN networks, depending on the type of sensors, can be deployed on the ground, in the air, under and over water, in buildings and, finally, on the skin and inside living organisms, including humans. They are also widely used in such important areas as military affairs, crisis and emergency management, and the fight against terrorism.

Dependability and standardization are essential to the adoption of Wireless Sensor Networks (WSN) in industrial applications. Standards such as ZigBee, WirelessHART, ISA100.11a and WIA-PA are, nowadays, at the basis of the main process-automation technologies. However, despite the success of these standards, management of WSNs is still an open topic, which clearly is an obstacle to dependability. Existing diagnostic tools are mostly application- or problem-specific, and do not support standard-based multi-network monitoring. This paper proposes a WSN monitoring architecture for process-automation technologies that addresses the mentioned limitations. Specifically, the architecture has low impact on sensor node resources, uses network metrics already available in industrial standards, and takes advantage of widely used management standards to share the monitoring information. The proposed architecture was validated through prototyping, and the obtained performance results are presented and discussed in the final part of the paper. In addition to proposing a monitoring architecture, the paper provides an in-depth insight into metrics, techniques, management protocols, and standards applicable to industrial WSNs.

Abstract
Information and communication technology are among the fastest growing industry sectors globally. One enabler for fast grow is created standards, which enables compatibility between technologies. This dissertation aims to create new knowledge concerning how standardization affects businesses that develop and sell technologies and technology-based products and services. More precisely this study focuses on the wireless telecommunication, which needs standards to function globally. This globalization and standardization development sets requirements for companies and organizations in the business; they are expected to be flexible, innovative, efficient, international, well resourced and cooperative. In order to achieve this on a global scale multiple actors – such as manufacturers, operators and developers – need to negotiate with a number of regional standardization bodies.
The standardization environment is under constant change; however, standards as such should remain stable. Understanding standardization processes has become important because new technologies, new forms of business organizations, trade issues and new institutions are emerging. All actors' in the standardization process should more thoroughly understand their role in the process, and recognize the important relations between the stages. From the actors' point of view the most beneficial issue in the wireless standardization process are networking and legitimacy of the process.
In this research we are interested in researching empirically how actors' can possibly benefit from standardization processes in their businesses. As actors' we regard as manufacturers, operators, regulators, standardization organizations and SMEs. It is important to identify key factors/inhibitors that shape the standardization process from the actors' point of view.
The theoretical framework of this study is built on the institutional theory. This theory provides a perspective as to how the actors can assimilate and act as part of the standardization environment. The broad reach of the institutional perspective is its major strength, making it potentially relevant to all levels of analyzis and all time spans, from micro-level interactions to large-scale changes in nation-states. Standardization creates opportunities for actors such as market and technology insights, internationalizing, and networking.
The a priori dynamic process model developed shows the complexity and length of the wireless standardization process. From the process point of view the important points are the openness of the process, networking, cooperation, technological points and changes in the process. The new points which arose from the material include IPR issues, research, open atmosphere, globalization, licensing issues, flexible working procedure and interpretation of standards and document management.
The empirical data of this study is derived by interviews. The interviews were carried out during autumn 1998, 2000 and winter 2004. 35 experts were interviewed from different bodies involved in 3rd generation wireless standardization and software companies.

Security of systems and services has been dominant research area in recent years as today's cloud services, big data and networked systems, especially when they provide wireless application access where personal and confidential data to be transmitted across the networked systems. Numerous tools and technologies are available to ensure system's security; however, external threats to computer systems and applications residents thereon, are also becoming more and more sophisticated and on the increase. Therefore, the key aim of this research is to integrate security engineering techniques and process with systems development life-cycle and process improvement frameworks. This paper presents a framework that consists of two components: 1) a security assessment model to looks at the existing security infrastructure of an organisation to determine its security maturity level; and 2) a security improvement maturity model to suggest an improvement mechanism for the organisation to progress from one maturity level to the next higher level. The intention is to provide a scheme to improve the organisation's Systems and network security with the aim that it becomes more efficient and effective than before.

Information Technology is one of the most rapidly developing areas in the technological world. In fact, the classical information technology that has been based on computer technology is now very quickly converging with telecommunication. Wireless networking, especially mobile telecommunications, has been one of the leading areas in business and technology during the last five years. The state-of-the art in mobile telecommunication has reached a point, where new products are introduced within a cycle of one year. The next big step shall be the introduction of wireless multimedia services through next generation wireless networks. The standardization of wireless multimedia systems is a very difficult task, as the standards shall include the crucial points in the two domains, telecommunications and information technology. It is becoming more and more difficult to recruit enough expertise for the technical committees to produce high quality standards in the converging information technology and telecommunication market domain. In this chapter, we will be using this domain as an example for the standardization difficulties of future. The reasons have to be strong for initiating a standardization process, especially concerning industry, due to the fact that it is rather expensive to produce new and extensive standards. It has been estimated that the expenses of developing a single part of the Ethernet standards amount to approx. $10,000,000 (Spring & Weiss, 1994). The main development costs arise from the time, travel and salaries of the committee members. The standardization expenses are usually prohibitive for small and medium sized enterprises (SMEs). If the standardization organizations and committees can not guarantee that the investments done towards standardization are worthwhile we will have lots of problems in the future.

Texto completo da fonteResumo:
This article analyses social networks by looking at the standard making processes. As a framework for analysis, actor network theory is chosen. Standards are of particular interest for actor network theory for they provide mechanisms to align interests of multiple social groups organized in networks that have a joint incentive in working with the standards and /or associated technologies. These social groups include scientific communities, government institutions and social movements (industrial groups, companies, and consumers) that are interested in regulating and innovating with new technologies. Standards provide the mechanisms to inscribe subsequent behaviors that are expected to become persistent over time. Standard making process is a social process. Actors are involved in the process of continuous negotiation of their interests. Due to this fact, standards became an object of analysis for scholars within the social shaping of technology theory (SST). Though usually scholars of this school take standards as material objects, they interpret technology as such, e.g., a bicycle, or a steam machines. In Information Technology (IT), domain standards are intangible. Those are electronic data exchange formats, communications protocols, signalling protocols, etc. Wireless and mobile communications in particular, being a large field of IT, represent an interesting case for analysis. Present in mobile telephony’s domain are de jure (e.g., GSM) and de facto standards (e.g., NMT). Also the broad scope and large scale of standardization processes suggests non-unified pattern of standard making and complex organizational structure. To make mobile telephony standards successful implies large networks and numerous mandatory passage points. In this paper we apply actor network theory based analysis (ANT) to the development of NMT wireless standards. Researchers interested in IT standardization, except for a few studies on electronic data interchange (EDI) by Hanseth (1997), have overlooked this approach. The acronym NMT stands for Nordisk MobilTelefon (Nordic Mobile Telephone) and it can be historically regarded as one of the best examples of Nordic cooperation in technology as NMT systems have spread quite widely around the world and it also formed an important stepping stone for the evolution of GSM standards. We chose for ANT analysis of the NMT standard making process to learn of the usefulness of theoretical framework and to understand the standard making process of NMT as a social and institutional change. In our opinion, this more than anything else, explains the success of this interesting historical incident that changed the telecommunication industry radically and made Scandinavia a powerhouse of the wireless technologies. Our approach expected to bring more understanding on how the enthusiasm of a small number of actors fostered successful development of the NMT cellular telephony standard. At the same time the NMT standard was based on concepts and visions of its developers. Yet, it was these visions and engagements that lead to distributed the big cake of the cellular world even before cutting it into pieces. The outline of the chapter is the following. In the next section, we discuss past theoretical analysis of the topic. Then we introduce new notions into ANT, such as a layer and a multilayered structure. Next we tell the story of the Nordic radio engineers’ gang. We then analyze the NMT standard’s development process as an instance of actor network mobilization. Some insights into future developments of cellular mobile communications, both from the technological and social perspectives are provided.

Texto completo da fonteResumo:
Standards have become critical to information and communication technologies (ICTs) as they become complex and pervasive. We propose a process theory framework to explain anticipatory standardizing outcomes post hoc when the standardizing process is viewed as networks of events. Anticipatory standards define future capabilities for ICT ex ante in contrast to ex post standardizing existing practices or capabilities through de facto standardization in the market. The theoretical framework offers the following: a) a lexicon in the form of the ontology and typology of standardizing events; b) a grammar, or a set of combination rules, for standardizing events to build process representations; c) an analysis and appreciation of contexts in which standardizing unfolds; and d) logic yielding theoretical explanations of standardizing outcomes based on the analysis of process representations. We show how the framework can help analyze standardization data as networks of events as well as explain standardizing outcomes. We illustrate the plausibility of the approach by applying it to wireless standardization to explain standardizing outcomes.

Texto completo da fonteResumo:
Narrowband internet of things (NB-IoT) is a low power wide area network technology with numerous benefits over conventional technologies. The main advantages of NB-IoT are low-power, low-cost, long battery life, wider deployment, and many more. Along with these advantages, knowledge of the location of the devices for both the indoor and outdoor environments will have an added benefit for NB-IoT applications. The current global navigation satellite systems (GNSS) chipsets will drain the limited available battery and will not be useful for localization in NB-IoT applications while the global positioning system (GPS) applications accuracy is not enough to support NB-IoT applications. For NB-IoT implementation, having low per-unit cost of the devices is an important aspect along with other features mentioned earlier, and hence there is a need to have limited hardware components like processor, battery, and memory. Therefore, the main challenge for enabling a positioning system lies in the proper radio management and balancing of power consumption against the performance of the system. In this chapter, different localization methods, techniques, and metrics are discussed. The choice of each one of these depends on the application requirement. The standardization of NB-IoT is in the process and its current status as per the 3rd Generation Partnership Project (3GPP) specifications are also highlighted.

Texto completo da fonteResumo:
The plethora of mobile multimedia services that are expected to face high penetration, poses the need for the deployment of a resource economic scheme in Long Term Evolution (LTE) networks. To this direction, the Evolved - Multimedia Broadcast / Multicast Service (E-MBMS) is envisaged to play an instrumental role for LTE proliferation and set the basis for a successful 4th Generation (4G) standardization process. One of the most critical aspects of E-MBMS performance is the selection of the most efficient radio bearer, in terms of power consumption. This chapter presents the prevailing radio bearer selection mechanisms and examines their performance in terms of power consumption. Furthermore, it discusses problems regarding the high power requirements for the realization of E-MBMS and evaluates the proposed techniques/solutions. Finally, this chapter presents a novel mechanism for efficient power control during E-MBMS transmissions that conforms to LTE requirements for simultaneous provision of multiple multimedia sessions.

New mobile architectures allow for stable networked links from almost everywhere; and more and more people make use of information resources for work and business purposes on mobile systems. Although technological improvements in the standardization processes proceed rapidly; many challenges; mostly aimed at the deployment of value-added services on mobile platforms; are still unsolved. In particular the evolution of wireless-enabled handheld devices and their capillary diffusion have increased the need for more sophisticated service discovery protocols (SDPs). Here we present an approach; which improves Bluetooth SDP; to provide m-commerce resources to the users within a piconet; extending the basic service discovery with semantic capabilities. In particular we exploit and enhance the SDP in order to identify generic resources rather than only services. We have integrated a “semantic layer” within the application level of the standard Bluetooth stack in order to enable a simple interchange of semantically annotated information between a mobile client performing a query and a server exposing available resources. We adopt a simple piconet configuration where a stable networked zone server; equipped with a Bluetooth interface; collects requests from mobile clients and hosts a semantic facilitator to match requests with available resources. Both requests and resources are expressed as semantically annotated descriptions; so that a semantic distance can be computed as part of the ranking function; to choose the most promising resources for a given request.
