The EUNICE (European Network of Universities and Companies in Information and Communication technology) (http://www.eunice-forum.org) mission is to jointly - velop and promote the best and most compatible standard of European higher edu- tion and professionals in ICT by increasing scientific and technical knowledge in the field of ICT and developing their applications in the economy. The EUNICE Wo- shop is an annual event. This year the workshop was sponsored by IFIP TC 6 WG 6.6: Management of Networks and Distributed Systems. Eight years ago, the seventh edition of the EUNICE workshop took place in Tro- heim with the topic “Adaptable Networks and Teleservices.” Since then “adaptability” has become a topic which is found in most ICT conferences. The concept teleservices, which is a telecommunication domain concept from the 1980s, has been lifted out of the telecom community and is now found with new and sometimes mysterious names such as service–oriented architecture and cloud computing.

This book constitutes the refereed post-conference proceedings of the 8th International Conference on Mobile Networks and Management, MONAMI 2016, held in Abu Dhabi, United Arab Emirates, in October 2016. The 14 revised full papers were carefully reviewed and selected from 18 submissions. The papers are organized thematically in four parts, starting with cloud computing and software defined networking followed by Internet-of-the-things, vehicular networks and novel techniques and algorithms.
