Context-Awareness Enhances 5G Multi-Access Edge Computing Reliability
The fifth generation (5G) mobile telecommunication network is expected to
support Multi- Access Edge Computing (MEC), which intends to distribute
computation tasks and services from the central cloud to the edge clouds.
Towards ultra-responsive, ultra-reliable and ultra-low-latency MEC services,
the current mobile network security architecture should enable a more
decentralized approach for authentication and authorization processes. This
paper proposes a novel decentralized authentication architecture that supports
flexible and low-cost local authentication with the awareness of context
information of network elements such as user equipment and virtual network
functions. Based on a Markov model for backhaul link quality, as well as a
random walk mobility model with mixed mobility classes and traffic scenarios,
numerical simulations have demonstrated that the proposed approach is able to
achieve a flexible balance between the network operating cost and the MEC
reliability.Comment: Accepted by IEEE Access on Feb. 02, 201
A User-Focused Reference Model for Wireless Systems Beyond 3G
This whitepaper describes a proposal from Working Group 1, the Human Perspective of the Wireless World, for a user-focused reference model for systems beyond 3G. The general structure of the proposed model involves two "planes": the Value Plane and the Capability Plane. The characteristics of these planes are discussed in detail and an example application of the model to a specific scenario for the wireless world is provided

Management and Service-aware Networking Architectures (MANA) for Future Internet Position Paper: System Functions, Capabilities and Requirements
Future Internet (FI) research and development threads have recently been gaining momentum all over the world and as such the international race to create a new generation Internet is in full swing: GENI, Asia Future Internet, Future Internet Forum Korea, European Union Future Internet Assembly (FIA). This is a position paper identifying the research orientation with a time horizon of 10 years, together with the key challenges for the capabilities in the Management and Service-aware Networking Architectures (MANA) part of the Future Internet (FI) allowing for parallel and federated Internet(s)
Work Organisation and Innovation - Case Study: Rabobank, Netherlands
[Excerpt] Rabobank Nederland (RN) is part of Rabobank Group, which provides financial services and insurance. It is the largest financial services provider in the Netherlands. The group operates in 47 countries and has an employee base of 59,670 full-time equivalents (FTE). In the Netherlands RN has an employee base of 6,800 FTE, which is more or less equal to 8,500 employees. RN is a cooperative, located in Utrecht, and the administrative centre for 139 (2011) local cooperative Rabobanks. The local banks are not branches of RN as each of them has its own banking licence from the central Nederlandsche Bank. The joint employee base of the local Rabobanks is 27,000 FTE. The 139 local Rabobanks, RN and affiliates, provide services to some 10 million clients, including 1.9 million members (Rabobank Annual Report, 2011)
Federated Robust Embedded Systems: Concepts and Challenges
The development within the area of embedded systems (ESs) is moving rapidly, not least due to falling costs of computation and communication equipment. It is believed that increased communication opportunities will lead to the future ESs no longer being parts of isolated products, but rather parts of larger communities or federations of ESs, within which information is exchanged for the benefit of all participants. This vision is asserted by a number of interrelated research topics, such as the internet of things, cyber-physical systems, systems of systems, and multi-agent systems. In this work, the focus is primarily on ESs, with their specific real-time and safety requirements.
While the vision of interconnected ESs is quite promising, it also brings great challenges to the development of future systems in an efficient, safe, and reliable way. In this work, a pre-study has been carried out in order to gain a better understanding about common concepts and challenges that naturally arise in federations of ESs. The work was organized around a series of workshops, with contributions from both academic participants and industrial partners with a strong experience in ES development.
During the workshops, a portfolio of possible ES federation scenarios was collected, and a number of application examples were discussed more thoroughly on different abstraction levels, starting from screening the nature of interactions on the federation level and proceeding down to the implementation details within each ES. These discussions led to a better understanding of what can be expected in the future federated ESs. In this report, the discussed applications are summarized, together with their characteristics, challenges, and necessary solution elements, providing a ground for the future research within the area of communicating ESs
The Court, FCC and Internet Policy: Partly with
The paper aims to explore the contour of internet regulation with a thread of
Brand X , which navigates through constitutionalism, separation of powers, as
well as business and economic or political implications enshrined behind it.
An exemplary insight with the Korean case was adverted that could lead to the
comparative perspective of internet law and regulation for the future research.
The research was conducted by employing qualitative investigation, mainly
relying on textual analysis and documentary examination. The outcome of
research generally corroborates with our assumption that i) the increasing
administrative state will variegate the traditional interplay of three branches,
ii) expert bureaucracy stands at the core of policy shaping because of the necessary
new concept of market and policy specialization, iii) the role of US
government is not only pioneering, but also influential as a regulator, but
comparatively with differing national jurisdictions if not a negligible implications
on the international competition or even conflict
