As the Internet has penetrated everyday life, more and more users will demand high-quality services. However, the Internet was not designed to handle such heavy usage. Thus, networks need to be enhanced in order to deal with the increased traffic. In this study, the use of opportunistic networks (ONs) is studied. ONs are operator-governed, coordinated(More)
The adoption of autonomic features in network management becomes a necessity to cope with the increasing complexity of the telecommunications ecosystem. The purpose of this paper is to present the concept of Unified Management Framework (UMF) developed in the FP7 UniverSelf project. The core of UMF comprises three functional blocks, namely Governance,(More)
This paper briefly proposes the demonstration of a prototype system that is able to successfully govern autonomic functions and to efficiently manage virtualized resources. The demonstration also showcases how Software-Driven Networks (SDNs) can be managed using the UMF architecture, as well as how novel optimization algorithms and mechanisms can be(More)
This paper proposes the exploitation of a Unified Management Framework for coordinating (i.e. ensuring conflict-free and stable operation), multiple, autonomic control loops. The functionality is demonstrated through the instantiation to Self-Organizing Network (SON) coordination for managing LTE-Advanced Heterogeneous Network (HetNet) with relays.
