The 19th Edition of Strategic Workshop (SW’17) held in, WESTIN DRAGONARA RESORT Dragonara Road, St. Julian’s STJ 3143, Malta on May 29–31, 2017. The focus during the active 2-day discussion was, Future Wireless Ecosystems (FWE) addressing concept, innovation, systems, network security, and future strategy.
The theme of the workshop was “Future Wireless Ecosystems (FWE).” In addition to the technical presentations on FWE, a significant goal of the workshop was to speed up innovation and the path to commercialization of the relevant technologies and a strong partnership between industries and academia. We believed that these pervasive wireless ecosystems would become an integral part of our world in the near-future and beyond. In fact, enabling such a ubiquitous communication and computing infrastructure will only further drive this revolution to fruition. To meet this objective, we organized a dedicated Panel and Sessions in the area of Future Wireless Ecosystems (FWE). During this workshop, we aimed to engineer communication and computing system which is unique, and it is intricately tied to supporting various human-centered applications while at the same time appearing to be seamless and invisible to end-users. Regarding critical enabling technologies, the communications/networking challenge is that of designing hierarchical, distributed, decentralized and adaptive protocols for dense wireless networks and integrating efficiently with the future Internet as a whole.
This Special Issue features selected Twelve papers that concentrate on a wide range of research challenges in Future Wireless Ecosystems (FWE) as well as addressing issues of application, services and security in coming wireless technologies and with this, technology-oriented innovative business models and standardization for Future Wireless Ecosystems and associated services.
The First Paper, “Co-tier Uplink Interference Management by Stackelberg Game with Pricing in Co-Channel Femtocell Networks”, by Chih-Cheng Tseng & Ching-Shun Peng.
This research paper has emphasized that the indoor signal quality of mobile communication has increased due to development of femtocell. Despite, as the femtocells are widely deployed, the uplink interference from different femtocells, i.e., the co-tier up-link interference, turns out to be a critical problem to jeopardize the performance of the entire network. The concept of Stackelberg game with pricing mechanism has discussed in this paper for solving this issue.
The Second Paper, “Deviceless Communications: Cloud-based Communications for Heterogeneous Networks”, by Flavio Meneses, Carlos Guimaraes, Tiago Magalhaes, Diogo Gomes, Daniel Corujo & Rui L. Aguiar.
This research paper depicts that mobile networks today see increasingly large numbers of connected User Equipments (UE), allowing users to go away voice calling and tap into costly online services. In this paper, authors proposed a device less communication approach. To support this, authors have presented a framework that explores and enhances Software Defined Network and Network Function Virtualisation concepts.
The Third Paper, “Performance Analysis of Space-Air-Ground Integrated Network (SAGIN) over an Arbitrarily Correlated Multivariate FSO Channel”, by Isiaka. A. Alimi, Akeem O. Mufutau, Antonio L. Teixeira & Paulo P. Monteiro.
This research paper is of the view that the Space-Air-Ground Integrated Network (SAGIN) system interconnect several networks to achieve a significant network topology that is capable of efficient sharing of global information and resources. However, support for drifting in the SAGIN system could be challenging for the FSO line-of-sight (LOS) links because of the requirement for alignment between the receiver and transmitter modules. In this paper, authors have considered the effect of arbitrarily correlated FSO channel on the system performance. To achieve this, authors employed exponential model for modeling the correlations between the apertures.
The Fourth Paper, “Virtualization approach for machine-type communications in multi-RAT environment”, by Liljana Gavrilovska, Valentin Rakovic & Aleksandar Ichkov.
This paper discussed about the virtualization approaches for MTC in a multi-RAT environment. Authors have also emphasized and discussed the benefits and practical aspects of MTC virtualization and evaluates the advantages and disadvantages of the Docker and OpenStack virtualization frameworks.
The Fifth Paper, “Research Challenges, Trends and Applications for Future Joint Radar Communications systems”, by Atílio Gameiro, Daniel Castanheira, Jéssica Sanson & Paulo P. Monteiro.
Dual functionality devices that integrate reflectometry and communication capabilities will be essential to reduce development costs through the reuse of modules and optimize the usage of radio resources namely spectrum. This paper is providing reviews for the main trends that push for the merging of radar type sensors and wireless communications (RadCom). It presents the most critical use cases that can currently be foreseen. It identifies the leading technology trends and issues to reach a mature technology, namely focusing on OFDM type waveforms that will enable smooth integration with 4G.
The Sixth Paper, “Advanced Business Model Innovation supported by Artificial Intelligence and Deep Learning”, by Per Valter, Peter Lindgren & Ramjee Prasad.
Authors have depicted that BMs increasingly run autonomously by machines, businesses should expect to be able and capable to innovated BMs and operated BMs in new Business Model Ecosystems (BMES) in the future. Authors have addressed the exponential development of artificial intelligence technologies, efficient technologies and persuasive BMs in Business model innovation and introduce a conceptual model to future business model innovation and operation.
The Seventh Paper, “Radio Hardware Virtualization for Software-Defined Wireless Networks”, by Felipe A. P. de Figueiredo, Xianjun. Jiao, Wei Liu & Ingrid Moerman.
Authors have discussed that the Current SDWN implementations are mainly using customized firmware, such as Open-WRT, running on an embedded application processor in commercial WiFi chips, and restricted to layers above lower Media Access Control (MAC). This limitation comes from the fact that radio hardware usually requires specific drivers, which have a proprietary implementation by various chipset vendors. Hence, it is difficult, if not impossible, to achieve virtualization on the radio hardware. Authors are investigating the necessity and feasibility of extending the virtualization of wireless networks towards the radio hardware. An SDR architecture is presented for radio hardware virtualization to facilitate SDWN design and experimentation.
The Eighth Paper, “Impact of Interference Between Neighbouring 5G Micro Operators”, by Kimmo Hiltunen, Marja Matinmikko & Matti Latva-aho.
Authors have proposed the concept of micro-operators with local spectrum micro-licensing that is needed to complement the traditional models based on networks deployed and operated by the mobile network operators. While evaluating the applicability of the proposed micro operator concept, one crucial aspect is to assess the impact of the inter-operator interference on the performance of the victim network when deployed in the same or adjacent channel. This paper proposes a deployment scenario including two neighboring buildings, propagation models for connections both within a structure and between the buildings, and criteria for the required minimum separation distance based on the observed throughput loss.
