This paper describes the deployment and experimentation architecture of the Internet of Things experimentation facility being deployed at Santander city. The facility is implemented within the SmartSantander project, one of the projects of the Future Internet Research and Experimentation initiative of the European Commission and represents a unique in the(More)
SmartSantander proposes a unique in the world city-scale experimental research facility in support of typical applications and services for a smart city. Tangible results are expected to greatly influence definition and specification of Future Internet architecture design from viewpoints of Internet of Things and Internet of Services. The facility will(More)
Security policy management for a dynamic coalition with multiple members, each with its own policy requirements and mechanisms, and with limited mutual trust, is a complex task. In this paper, we present the architecture of MSME, a system that addresses this problem by providing mechanisms to express security requirements for large groups abstractly;(More)
In many applications (like social or sensor networks) the information generated can be represented as a continuous stream of RDF items, where each item describes an application event (social network post, sensor measurement, etc). In this paper we focus on compressing RDF streams. In particular, we propose an approach for lossless RDF stream compression,(More)
Bio-inspired cyclopeptidic heterodimers built on beta-sheet-like hydrogen-bonding networks and bearing photoactive and electroactive chromophores on the outer surface have been prepared. Different cross-strand pairwise relationships between the side chains of the cyclic alpha,gamma-peptides afford the heterodimers as three nonequivalent dimeric species.(More)
In this paper we introduce a high level architecture for a context management system for personal networks (PN). The main objective of the context management framework (CMF) described in this paper is to support the interactions between context information sources and context aware components, services and applications in a generic manner, independently of(More)
Personal Network (PN) is an emerging concept which combines pervasive computing and strong user focus. The idea is that the user's personal devices organise themselves in a secure and private personal network transparently of their geographical location. This paper studies a PN architecture where devices form clusters using shared key cryptography over(More)
This paper presents a methodology for hardware-software co-design. It is based on the formal description technique LOTOS in the specification phase, and on estimation methods at different levels of abstraction in the partitioning phase. The LOTOS specification describes the system as a set of interacting communicating processes. Our HW-SW partitioning(More)
