Abstract: This study shows how a maturity model on Green ICT can help organisations become more environmentally sustainable in a structured and efficient manner. For this we have used the SURF Green ICT Maturity Model and facilitated the use of this model in four organisations. These organisations participated in a maturity scan, an evaluation session to discuss the results of the scan and a questionnaire on the use of the model. The results show that the model delivers specific suggestions for improvement both on reducing the environmental footprint of ICT and on using ICT as a green solution for business processes. Individual participants reported an increase in awareness on what Green ICT can do.We also looked at whether organisations were ready to use Green ICT and identified potential bottlenecks for further adoption and it was possible to identify such bottlenecks using the results of the maturity scan.

Keywords: Green ICT, ICT for Sustainability, Green IS, Maturity Model, Assessment.

Abstract: Several competitive standards have been introduced, which define smart city’s development framework, architecture and components or city’s key performance indicators. However, these standards have not introduced specifications for smart services, nor for policy making process modelling, although standardization assists in achieving process automation by introducing “best practices” as standard process models. Policy making mainly follow non-standardized procedures, even if it is supported by various typical methodologies (i.e., Multi-Criteria Decision Methods (MCDM)). This paper is inspired by the Task-Based Modelling method (TBM) and focuses on policy making process standardization for smart cities. More specifically, in introduces aTBMschema for policy making regarding city’s energy efficiency, which an important smart city aspect. This TBM is based on the outcomes of the case-study of the Integrative Smart City Planning (InSmart) coordination action in the smart city of Trikala, Greece.

Keywords: Standardization, smart city, policy making, decision making, case study, TBM.

Abstract: Access to the television white space by white space devices comes with a major technical challenge: white space devices can interfere with existing television signals. Two methods have been suggested in the literature to help white space devices identify unused channels in theTVfrequency band so that they can avoid causing harmful interference to primary users; geo-location spectrum database and spectrum sensing. Discussions in the literature have placed much emphasis on the limitations of the spectrum sensing approach mainly from the perspective of the developed world environment in which its drawbacks are significant. Little attention has been placed to the limitations of the geo-location database approach when applied in a developing regions. This paper considers a broader analysis of the approaches by looking at factors that can affect their performance and how the presence or absence of these factors in a developed region or developing region can affect their applicability. In so doing, the paper highlights the need to conduct more research on the performance of spectrum sensing in developing regions where there are much less TV broadcasting stations and therefore, white spaces are more abundant.

Keywords: Geo-location database, spectrum sensing, performance factors, best approach.
