This book constitutes the thoroughly refereed proceedings of the fourth
International Conference on Mobile Networks and Management, MONAMI 2012,
held in Hamburg, Germany, in September 2012. The 15 revised full papers
presented were carefully selected and reviewed from numerous
submissions. In addition two well-received workshops are presented: the
second MONAMI Workshop on Smart Objects and the first Open Connectivity
Services Workshop, organized in cooperation with the EU FP7 SAIL
project. All in all, 25 papers were orally presented at the conference.
The papers are organized in five topical sections: mobile networks,
heterogeneous networks, wireless communications, smart objects and IoT
applications, and future networks.
