BUSINESS IMPACT ASSESSMENT OF SELF-GROWING ENERGY EFFICIENT SYSTEMS
This paper investigates the business impact of two novel mechanisms that increase the energy efficiency of networks, i.e. sensor network decentralisation and system idle time estimation, which have been developed in the CONSERN project. The analysis consists of two distinct but interrelated phases, the objective of which is to combine a techno-economic analysis of actual gains as contained within the technical KPIs of optimisation techniques, with a strategic analysis of factors promoting or hindering the actual introduction of these mechanisms within mobile business ecosystems. In the first phase, the technical gains of the two mechanisms are translated into an estimation of Operational Expenditure (OPEX) savings for a number of typical configurations. Subsequently, a business impact assessment is performed, in which two commercial deployment modes – an operator based and operator independent mode – are outlined. After having drawn up the business ecosystem for these two deployment models, a number of business opportunities and challenges for the two mechanisms in the different deployment modes are identified using the business model framework developed by Ballon, and a scorecard is used to weigh the importance of the various business model parameters against each other. The paper concludes with some recommendations and steps to mitigate disjunctions and improve synergies between the key stakeholders, constituting a sustainable business ecosystem

Published research manuscripts related to safety and security in collaborative learning environments have been explored, and the research topics with which researchers and practitioners deal with are discussed, as well as implications for researchers and practitioners. This paper argues that Web 2.0 learning environments entail threats and challenges in the safety of both students and instructors, and further research needs to take place for handling and protecting the privacy of all involved stakeholders
Optimal Periodic Radio Sensing and Low Energy Reasoning for Cognitive Devices
Heterogeneous wireless access networks have emerged as a paradigm that
offers the potential for increased flexibility, improved QoS and higher
data rates. New, dedicated radio channels conveying context information
from the network to the terminal as well as terminal observations back
to the network have been proposed to facilitate terminal operation in
such environments. On the other hand, low energy and “green” aspects
are becoming increasingly important, not only for environmental reasons
but also because low energy systems offer extended battery duration,
reduced operational cost and improved long-term reliability. This work
proposes a solution to the problem of low energy periodic sensing of
available networks, focusing on the definition of optimal sensing period
through markovian models. Moreover, low energy decision making utilizing
a hierarchical fuzzy logic approach consisting of reasoners organized in
tree form is introduced. The input parameters of the system are grouped
taking into consideration their interrelation, in order to define the
position of each reasoner in the structure. Such an approach facilitates
utilization of previous knowledge and triggers a minimal number of
reasoners, thus considerably reducing energy costs

Cyber security risks for minors: a taxonomy and a software architecture
The explosion of the Internet provides a variety possibilities for communication, finding information and many other activities, turning into an essential tool in our modern everyday life. However, its huge expansion globally has created some serious safety issues, which require a special approach. One of these issues and perhaps the most important one concerns the safety of children on the Internet, as they are more exposed to dangers and threats in comparison with adults. In order to design effective measures against these threats and dangers deep understanding of minors' activities on the Internet, along with their motivation, is a first necessary step. It is shown in this report that minors' Internet activity tends heavily, and in an increasing manner, towards Online Social Networks (OSN). Thus, Internet filtering techniques designed and applied so far for child online protection need to be reconsidered and redesigned in a smarter way such as data analytics, advanced content analysis and data mining techniques are incorporated. OSN fake account identification, sexual content detection and flagging of multiple OSN accounts of the same person are examples that require such sophisticated techniques. This study deals with a literature review concerning the Internet activity and motivation of use by minors and presents in a coherent manner the identified risks and threats that children using the web and online social networks are exposed to. It also presents a systematic process for designing and developing modern and state of the art techniques to prevent minors' exposure to those risks and dangers

IEEE P1900.B: Coexistence support for reconfigurable, heterogeneous air interfaces
This contribution presents and discusses the system concept approach
which has been proposed by the European Integrated Project IST-(ER)-R-2
II in the IEEE P1900.B Standardization Study Group (SG); it currently is
under further elaboration in the framework of the follow-up IEEE
P11900.4 Working Group (WG) whose Project Authorization Request (PAR)
was accepted in December 2006. This effort targets reconfigurable
(typically Software Defined Radio (SDR) based) networks and terminals in
a heterogeneous wireless environment, with multi-homing capable
terminals enabling, the users to operate multiple wireless links
simultaneously. In order to ensure backwards compatibility to legacy
standards, the approach is to introduce three new building blocks into
the (existing and/or evolving) heterogeneous landscape: i) A Network
Reconfiguration Management module, ii) a Radio Enabler and iii) a
Terminal Reconfiguration Management module. Within this paper, the key
functionalities of these building blocks are detailed and discussed; it
is furthermore outlined how the introduction of distributed
decision-making concepts improves the efficiency of the heterogeneous
system in terms of i) signaling overhead, ii) reactivity of user mobile
terminals (MTs) and iii) numerical resource selection optimization
complexity on the network side
Creative rings for smart cities
In order to make an impact on citizens' lives, projects within the framework of Smart Cities shall address - along with safety and transportation issues - shared services based on novel as well as creative applications that exploit Future Internet platforms and relevant network infrastructures. It is individual creativity, skills and talents, which lie at the crossroads between arts, business and technology, that provide a strong competitive advantage in novel applications aiming at the production and the commercialization of creative content. The vision of the SPECIFI project for European Creative Rings is presented in this paper. Creative communities are in most cases isolated from their counterparts in other cities having no access to Future Internet technologies and solutions. SPECIFI proposes the use of Creative Rings as a means of sharing creative and innovative content and enabling internet activities all over Europe. Thus Creative Rings intend to bring together infrastructure solutions that facilitate the use of future internet systems and applications. Creative Industries may experiment and deploy these systems and take advantage of the distribution of innovative content. Creative Rings are presented herein in terms of scenarios, infrastructures and applications
