Abstract: Spectrum sensing’s inability to provide maximum protection to primary users operating in television white spaces summarizes the technical challenges associated with it. Building upon “WhiteNet”, a white space network management platform for campus connectivity, this paper proposes design principles that can be incorporated in a white space identification system based on a cooperative spectrum sensing model that both minimizes the probability of causing interference to primary users due to false negatives and reduces false positives thereby increasing the amount of white spaces identified. Real-world indoor measurements of a TV transmitter signal were used to evaluate the proposed principles. The results reveal the relevance of using these design principles in white space networking using the emerging White-Fi protocol.

Keywords: White-Fi, cooperative spectrum sensing, detection threshold, spectrum sensing principles.

Abstract: Formal methods based on abstract models are becoming more and more important in the domain of complex computer networks. On the other hand, processes of design documentation transformation into the formal models are still bound to the skills and ingenuity of individual engineers. Moreover, the human factor involved in data transformation represents a major bottleneck due to the tendency of computer networks to be more and more complex. To address this problem, this work introduces a formal model based on the concept of multilayer networks for applying a system methodology to network analysis and an appropriate presentation format of architecture descriptions as a possible part of detailed design documentation that could allow automated generation of trusted formal multilayer models based on this documentation.

Keywords: computer networks, design documentation, formal models, multilayer networks.

Abstract: The aim of eHealth infrastructure is to harness innovations in digital infrastructure that can enable the seamless access to, sharing and reuse of data (e.g. clinical records, genomic data and images) irrespective of source [1]. eInfrastructure is comprised of networked, interoperable, service-oriented, scalable computational tools and services. The key element is the interaction of human users and computers so as to facilitate discovery, linking and reasoning.
