Guest Editor Foreword

The Kaleidoscope academic conference is ITU's flagship academic event. Established in 2008, the conference has been welcomed with great enthusiasm by the ICT research community and has matured into one of the highlights of the ITU's calendar of events.

Kaleidoscope's principal aim is to shed light on information and communication technology (ICT) research at an early stage so as to identify associated standardization needs in the interests of promoting the widespread diffusion of research findings through the development of internationally recognized ITU standards.

The sixth edition of the conference, ITU Kaleidoscope 2014, took the theme "Living in a converged world - impossible without standards?". It was tackled from a variety of perspectives in line with the multidisciplinary approach mandated by the all-encompassing nature of technological and industrial convergence.

From a total of ninety-eight submissions from thirty-nine countries, a double-blind, peer-review process selected thirty-four papers for presentation at the conference, all of which were published in the Kaleidoscope Proceedings as well as the IEEE Xplore Digital Library.

This is the first in a series of four special issues to showcase extended versions of selected Kaleidoscope papers, with the series planned as follows:

1. Special issue-1: Towards 5G
2. Special issue-2: e-Health and Standards
3. Special issue-3: Standardization, Education and Innovation
4. Special issue-4: Assessments, Models and Evaluation

This first special issue, "Towards 5G", includes a collection of Kaleidoscope papers that address questions essential to the development and rollout of '5G' mobile-wireless technologies.

Topics covered pertain to a range of subjects relevant to the development of the 5G ecosystem, spanning from services in cyberspace to the Internet of Things, dynamic use of radiofrequency spectrum, and security. The five papers and their respective authors are as follows:

• Proposal of "Cyber Parallel TrafficWorld" Cloud Service. Yoshitoshi Murata (Iwate Prefectural University, Japan); Shinya Saito (Iwate Prefectural University Graduate School, Japan)
• Standardizing the Internet of Things in an evolutionary way. Subin Shen (Nanjing University of Posts and Telecommunications, P.R. China); Marco Carugi (China Unicom, France)
• ANon-cooperative TVWhite Space Broadband Market Model for Rural Entrepreneurs.
  
  Sindiso Mpenyu Nleya (Computer Science Department, South Africa); Bigomokero Antoine Bagula (University of Western Cape, South Africa); Marco Zennaro (ICTP - The Abdus Salam International Centre for Theoretical Physics, Italy); Ermanno Pietrosemoli (International Centre for Theoretical Physics (ICTP), Italy)
• Performance evaluation of a dual diversity reception base on OFDM RoFSO systems over correlated log-normal fading channel. Fan Bai (Waseda University, Japan); Yuwei Su (Waseda University, Japan); Takuro Sato (Waseda University, Japan)
• A Mutual Key Agreement Protocol To Mitigate Replaying Attack In eXpressive Internet Architecture (XIA).
  
  Beny Nugraha (Mercu Buana University, Indonesia); Rahamatullah Khondoker (Fraunhofer SIT, Germany); Ronald Marx (Fraunhofer SIT, Germany); Kpatcha Bayarou (Fraunhofer Institute for Secure Information Technology, Germany)

We would like to thank the authors for their preparation of extended papers, the papers' reviewers for their generous contribution of time and expertise, and of course the readers of this journal for their interest and feedback on this first Kaleidoscope special issue.
