Reference Scenarios and Key Performance Indicators for 5G Ultra-dense Networks
Campos, Luís Miguel; Ribeiro, Luís; Karydis, Ioannis; Karagiannis, Stelios; Pedro, Dário; Martins, Jorge; Marques, Carlos; Armada, Ana GarcíaThe so-called 5G will revolutionize the way we live, and work. In order to demonstrate the profound changes, we can expect to experience within the next 5 to 10 years, we present use cases for the planned research within the TeamUp5G project. Some use cases are strongly linked to the network layer and aim at developing solutions capable of optimizing the main promising benefits of 5G: extremely low latency and ...
Integration and assessment of students in higher education: case study
Lopes, Duarte Barroso; Lopes, Patrícia; Campos, Luís Miguel; Moreira, José MiguelHigher Education in Portugal results from the reformulation initiated by the Bologna Declaration (1999). The student-centred training, which gives greater freedom in its training, also requires greater responsibility and introduces continuous assessment as an important parameter in evaluation. Twenty years after its implementation, the goal of this work is a reflection on the continuous evaluation applied in tw...
On the physical layer security characteristics for MIMO-SVD techniques for SC-F...
Madeira, João; Guerreiro, João; Dinis, Rui; Montezuma, Paulo; Campos, Luís MiguelMulti-Input, Multi-Output (MIMO) techniques are seeing widespread usage in wireless communication systems due to their large capacity gains. On the other hand, security is a concern of any wireless system, which can make schemes that implement physical layer security key in assuring secure communications. In this paper, we study the physical layer security issues of MIMO with Singular Value Decomposition (SVD) ...
Architectures and tools enabling seamless mobility in future collaborative netw...
Torres, M. J.; Anagnostopoulos, Ioannis; Campos, Luís Miguel; Correia, Nuno; Dimitriou, Nikos; Miranda, Jorge; Santos, Luiz; Sarakis, LambrosThis paper focuses on the concept of the seamless mobility (provided by vertical handover mechanisms) in heterogeneous Future Internet Networks in the context of the HURRICANE project. We discuss future open collaborative network architectures and propose a set of entities that ensure seamless mobility and service continuity, from infrastructural/operational and business standpoints: an 802.21-like implementati...
