  • Admission and Eviction Control of Cognitive Radio Users at Wi-Fi 2.0 Hotspots

    Kim, Hyoil; Shin, Kang G. (IEEE COMPUTER SOC, 2014-04-10)
    Cognitive radio (CR)-based Wi-Fi 2.0 hotspots are introduced as an attractive application of dynamic spectrum access (DSA), at which a wireless service provider (WSP) leases licensed channels via secondary market and offers Internet access to CR-enabled customers by opportunistically utilizing the leased spectrum. The CR users access the channels only when they are temporarily unoccupied by their legacy users, and pay a usage charge according to the WSP's pricing policy. In this paper, we study the profit maximization problem of a WSP by deriving the (sub) optimal control of admission (at CR user arrivals) and eviction (upon return of the legacy users) of CR users. We formulate the problem as a semi-Markov decision process (SMDP) with two quality-of-service (QoS) constraints on arrival-blocking and service-dropping probabilities, which is solved by the linear programming techniques. Using an extensive numerical analysis, we show that the derived policy achieves up to 22.5-44 percent more profit than simple complete-sharing algorithms in the tested scenarios. In addition, we evaluate the impact of the number of leased channels and pricing on the achieved profit, and study the tradeoffs between the two QoS constraints.
  • European Contract Law and the Digital Single Market. The Implications of the Digital Revolution.

    De Franceschi, A; De Franceschi, A (Intersentia, 2016)
    The EU is committed to making the Single Market fit for the digital age, by enhancing the protection of consumers and data subjects, while providing businesses with the legal certainty they need to invest in this field and support growth and innovation. In this context, European Contract Law and the Digital Single Market addresses the impact of digital technology on European Contract Law in light of the latest legislative developments including the EU Regulation of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on free movement of such data, as well as the European Commission’s proposals of 9 December 2015 for a Directive on the supply of digital content, for a Directive on online and other distance sale of goods and for a Regulation on the cross-border portability of online content services in the internal market. The book analyses new and urgent issues in the field of contract, data protection, copyright and private international law: namely the EU approach to personal information as a tradeable commodity and as the object of a fundamental right of the individuals concerned, the protection of consumers’ and users’ rights in contracts for the supply of digital content and on online and other distance sales of goods, the cross-border portability of online content services, the new features of standard contracts in the digital market and the issues surrounding the emergence of the so called platform economy. This edited collection aims to provide clear answers to the challenges posed by the digital revolution and to act as a basis for further developments of EU law.
  • El derecho fundamental al olvido: reconocimiento y evolución

    Torres Manrique, Jorge Isaac (Universidad Nacional de Colombia - Sede Bogotá - Facultad de Derecho, Ciencias Políticas y Sociales, 2018-01-01)
    El derecho fundamental al olvido es un nuevo derecho que surge como resultante negativo del desarrollo de la tecnología. Así, el derecho al olvido se encuentra orientado a impedir y contrarrestar los perjuicios que genera la no poca y dañina información personal publicada en la red. En la presente entrega, el autor analiza de manera profunda y amplia los diversos alcances y aristas de este derecho, para concluir esbozando propuestas al respecto.
  • Implementing Electronic Business Registry Services

    Lewin, Anat; Satola, David; Symonds, Richard; Sirtaine, Sophie; Lanvin, Bruno; Klapper, Leora (2015-07-07)
    The objective of this paper is to share
 the experiences and good practices of early business
 registry reformers who implemented web-enabled and automated
 electronic business registries (e-BRs). These lessons are
 hoped to be of help to EU New Member countries as they
 embark on delivering EU-conformant e-BRs. At the same time,
 policymakers in other developing countries may also find
 these lessons of use. This paper cites examples of good
 practices rather than best practices. As elsewhere in the
 development agenda, solutions that have worked well in some
 countries may not work in other local circumstances. In the
 case of e-BRs, success depends on a broader set of reforms;
 as will be discussed in a subsequent chapter, e-BRs require
 a supportive legal and regulatory infrastructure, such as
 electronic signature laws and document authentication. A
 needs assessment and analysis of the options in the local
 country context need to be conducted in order to find the
 most relevant best practice options for a specific country.
 Nevertheless, a number of practical good practices can be
 identified and are presented in this paper for consideration.
