S3.4 Accelerating the introduction of spectrum sharing using market-based mechanisms.
Fernando Beltrán (University of Auckland, New Zealand)

Spectrum management needs to be effective, in that spectrum must be allocated to the right uses,
and efficient, in that spectrum must be assigned to those that value it the most. Technological
advances and demands for further spectrum availability from mobile broadband operators (among
others) require spectrum management to timely and firmly incorporate schemes to increase the
technical efficiency of spectrum utilisation. One such scheme is spectrum sharing which has the
potential to result in higher spectrum utilisation and greater spectrum value. In such context
allocation and assignment, two critical functions to manage the spectrum, are also discussed. It is
argued that in the course of deciding about allocation and assignment of spectrum, a spectrum
authority can and should include market-based mechanisms that incentivise incumbents to share
spectrum needed by entrants.

Current trends in telecommunication networks foresee the adoption of the fifth generation (5G) of
wireless networks in the near future. However, a large number of people are living without
coverage and connectivity. To face this issue, we consider the possibility of deploying 5G networks
in rural and low-income zones. After detailing the current state-of-the-art, we consider the main
challenges that need to befaced. Moreover, we define the main pillars to follow in order to deploy
5G networks in such zones, as well as a proposal of a future network architecture.

S4.2 Design of scalable directory service for future IoT applications.

Information and Communications Technology, Japan)
Unprecedentedly a massive number of devices are getting connected in the coming era of the
Internet of Things (IoT). For discovery, remote access and management of these IoT devices, an
IoT directory service is needed to store and provide their various attributes such as location,
generated data types, owner’s name, and security keys. In this paper, we present the architectural
design of the IoT directory service that is capable to store a huge number of heterogeneous records
and provide fast lookup (latency of few milliseconds) and dynamic update (latency of few
seconds), while fully complying with owner- or user-centric security and privacy policy. To meet
the performance requirements despite fluctuations in the workload and networking environment,
we leverage tools of network function and resource virtualization to dynamically allocate and
adjust the computational and network resources assigned to the directory service.
