TL;DR: The usage of a network composed by Unmanned Aerial Vehicles (UAVs) as a relay network to guarantee the delivery of data produced by WSN nodes on the ground to the users is proposed.
Abstract: An important problem in Wireless Sensor Networks (WSN) is the occurrence of failures that lead to the disconnection of parts of the network, compromising the final results achieved by the WSN operation. A way to overcome such problem is to provide a reliable connection to support the connectivity via other types of nodes that communicate with the sensor nodes. This paper proposes the usage of a network composed by Unmanned Aerial Vehicles (UAVs) as a relay network to guarantee the delivery of data produced by WSN nodes on the ground to the users. Results from simulations of the proposed technique are provided and discussed.

TL;DR: The target applications and major open research challenges as well as the recent achievements by industry, academia, and the standardization bodies are identified and certain prospective research directions in the field are identified.
Abstract: Terahertz frequency band, 0.1–10THz, is envisioned as one of the possible resources to be utilized for wireless communications in networks beyond 5G. Communications over this band will be feature a number of attractive properties, including potentially terabit-per-second link capacities, miniature transceivers and, potentially, high energy efficiency. Meanwhile, a number of specific research challenges have to be addressed to convert the theoretical estimations into commercially attractive solutions. Due to the diversity of the challenges, the research on THz communications at its early stages was mostly performed by independent communities from different areas. Therefore, the existing knowledge in the field is substantially fragmented. In this paper, an attempt to address this issue and provide a clear and easy to follow introduction to the THz communications is performed. A review on the state-of-the-art in THz communications research is given by identifying the target applications and major open research challenges as well as the recent achievements by industry, academia, and the standardization bodies. The potential of the THz communications is presented by illustrating the basic tradeoffs in typical use cases. Based on the given summary, certain prospective research directions in the field are identified.

TL;DR: The state-of-the-art in technology, regulation and standardisation of cognitive access to TVWS is reviewed and the spectrum opportunity and commercial use cases associated with this form of secondary access are examined.
Abstract: Cognitive radio is being intensively researched as the enabling technology for secondary access to the so-called TV White Spaces (TVWS), large portions of spectrum in the UHF/VHF bands which become available on a geographical basis after digital switchover. Both in the US, and more recently, in the UK the regulators have given conditional endorsement to this new mode of access. This paper reviews the state-of-the-art in technology, regulation and standardisation of cognitive access to TVWS. It examines the spectrum opportunity and commercial use cases associated with this form of secondary access.

TL;DR: The architecture of the future networks must consider all the gaps of already existing networks in order to ensure the highest robustness, extremely low latency, Ubiquitous coverage as new applications and services require.
Abstract: New technologies are approaching with big footsteps. In the decades ahead it is expected significant changes in technologies regarding to new types of devices, system and functions that they perform. We are expecting new services with various requirements, and new applications such as holographic telepresence, instant data transmission, remote surgery, minimized IoT terminals, autonomous transportation system, etc. Wide adaptation of new applications depends on how good they are supported by the network infrastructure. That is why the estimation of next generation network architecture is required. By the year 2030 the applications of new technologies are expected to generate an enormous amount of traffic. The architecture of the future networks must consider all the gaps of already existing networks in order to ensure the highest robustness, extremely low latency, Ubiquitous coverage as new applications and services require.

TL;DR: A comprehensive survey of recent energy-efficient medium access control protocols for wireless body area networks (WBANs) and a comparison of the various approaches pursued is presented and a number of open research challenges are put forward.
Abstract: In this paper, we provide a comprehensive survey of recent energy-efficient medium access control (MAC) protocols for wireless body area networks (WBANs) and presents a comparison of the various approaches pursued. At the outset, we outline the crucial attributes for a good MAC. Several sources that contribute to the energy inefficiency are identified. Then, we investigate few MAC protocols devised for WBAN by emphasizing their salient features. As a conclusion, we put forward a number of open research challenges with regard to prospects of medium access techniques and other issues.
