Regulatory and Policy Implications of Emerging Technologies to Spectrum Management

This paper provides an overview of the policy implications of technological developments, and how these technologies can accommodate an increased level of market competition. It is based on the work carried out in the SPORT VIEWS (Spectrum Policies and Radio Technologies Viable In Emerging Wireless Societies) research project for the European Commission (FP6)spectrum, new radio technologies, UWB, SDR, cognitive radio, Telecommunications, regulation, Networks, Interconnection

Cost-Effective Situational Awareness Through IoT COTS Radios

Situational awareness (SA) through encrypted connectivity in modern warfare is critical to battlefield coordination. Existing solutions provide infrastructure-less connectivity and situational awareness, but at a high cost, power consumption, and bulky form factors that limit their utility for tactical operations. We propose the Beartooth MKII radios as a cost- and power-effective, handy solution for establishing a situational awareness overlay. To integrate with military information brokers, such as the Tactical Assault Kit (TAK), we propose the Beartooth Gateway, which creates an IP network between Beartooth radios, Gateways, and other TAK-capable devices. We show that leveraging Internet of Things (IoT) Commercial Off The Shelf (COTS) components for MKII and the Gateway can enhance the availability of SA and meet the user requirements in the field while ensuring compatibility with existing IP networks connected to TAK infrastructure.Comment: 6 pages, 3 figures, targeted to IEEE MILCOM conferenc

Current challenges and future trends in the field of communication architectures for microgrids

[EN] The concept of microgrid has emerged as a feasible answer to cope with the increasing number of distributed renewable energy sources which are being introduced into the electrical grid. The microgrid communication network should guarantee a complete and bidirectional connectivity among the microgrid resources, a high reliability and a feasible interoperability. This is in a contrast to the current electrical grid structure which is characterized by the lack of connectivity, being a centralized-unidirectional system. In this paper a review of the microgrids information and communication technologies (ICT) is shown. In addition, a guideline for the transition from the current communication systems to the future generation of microgrid communications is provided. This paper contains a systematic review of the most suitable communication network topologies, technologies and protocols for smart microgrids. It is concluded that a new generation of peer-to-peer communication systems is required towards a dynamic smart microgrid. Potential future research about communications of the next microgrid generation is also identified.This work is supported by the Spanish Ministry of Economy and Competitiveness (MINECO) and the European Regional Development Fund (ERDF) under Grant ENE2015-64087-C2-2.

A Taxonomy of Self-configuring Service Discovery Systems

We analyze the fundamental concepts and issues in service discovery. This analysis places service discovery in the context of distributed systems by describing service discovery as a third generation naming system. We also describe the essential architectures and the functionalities in service discovery. We then proceed to show how service discovery fits into a system, by characterizing operational aspects. Subsequently, we describe how existing state of the art performs service discovery, in relation to the operational aspects and functionalities, and identify areas for improvement
