Conference Paper
Full-text available
Massive IoT deployments in smart cities pose a significant challenge to the data collection due to the harsh wireless channel conditions of dense urban environments. Aerial reconfigurable intelligent surfaces (RIS) carried by Unmanned Aerial Vehicles (UAVs) can improve the communication thanks to their high mobility that provides line-of-sight prop...

Next generation networks, as the Internet of Things (IoT), aim to create open and global networks for connecting smart objects, network elements, applications, web services and end-users. Research and industry attempt to integrate this evolving technology and the exponential growth of IoT by overcoming significant hurdles such as dynamicity, scalab...
Article
As industries are under pressure for shorter business and product lifecycles, there is an extensive effort from the research community for novel and profitable automation processes. This effort has given rise to the 5G Tactile Internet, which is characterized by extremely low latency communication in combination with high availability, reliability...
Chapter
This work proposes a novel cooperative energy management scheme for the optimum management of the energy generated, stored, and consumed at microgrids. The proposed scheme considers that the microgrid comprises buildings of various types with diverse load profiles, which are able to exchange energy so that an optimal utilization of the energy gener...
Conference Paper
Full-text available
This paper describes in detail the design of a 5G platform based on the C-RAN architecture, with a fully virtualized Radio Access Network (RAN) and an optical/wireless Fronthaul. The wireless and optical domains are controlled by a hierarchy of Software Defined Networking (SDN) controllers, which are responsible for end-to-end optimization of the p...

Emerging 5G communication paradigms, such as machine-type communication, have triggered an explosion in ad-hoc applications that require connectivity among the nodes of wireless networks. Ensuring a reliable network operation under fading conditions is not straightforward, as the transmission schemes and the network topology, i.e., uniform or clust...
Article

In spite of the significant advancements in wireless connectivity, the static form of the network infrastructure cannot guarantee an uninterrupted operation of the ever-growing wireless consumer electronics in emergency situations such as natural disasters. In such occasions, employing flexible aerial nodes can tackle this issue by recovering the c...
Conference Paper
Full-text available
As wearables provide new health-related functionalities, they can be employed in hospitals to monitor patients and notify the medical personnel regarding their status. However, in order to be approved by the medical community, wearables need to have reliable communication and high lifetime. In such scenarios, it is important to know the probability...
Conference Paper
Full-text available
The emerging Internet of Things paradigm has triggered an explosion in ad-hoc applications that require connectivity among the nodes of wireless networks. However, the channel randomness and the random deployment of such networks could cause missed detections by isolated (i.e., unable to disseminate their messages) or inactive (i.e., without enough...
Conference Paper
Current mobile communication infrastructure may fail in cases where low coverage areas suddenly become overcrowded by mobile devices or in natural disasters. In this paper, we propose the use of flexible aerial relay (FAR) nodes for communication recovery and device-to-device (D2D) relaying, as an energy efficient and cost-effective way to resolve...

As large-scale dense and often randomly deployed wireless sensor networks (WSNs) become widespread, local information exchange between co-located sets of nodes may play a significant role in handling the excessive traffic volume. Moreover, to account for the limited life-span of the wireless devices, harvesting the energy of the network transmissio...
Conference Paper
Full-text available
Random dense deployment of heterogeneous networks (HetNets), consisting of macro base stations (BS) and small cells (SC), can provide higher quality of service (QoS) while increasing the energy efficiency of the cellular network. In addition, it is possible to achieve lower deployment cost and, therefore, maximize the benefits for the network provi...

In this letter, we study the performance of network coding (NC)-aided cooperative communications in large scale networks, where the relays are able to harvest energy emitted by wireless transmissions. In particular, we derive theoretical expressions for key network performance metrics, i.e., the probability of successful data exchange and the netwo...
