Internet of Unmanned Aerial Vehicles: QoS Provisioning in Aerial Ad-Hoc Networks

Aerial ad-hoc networks have the potential to enable smart services while maintaining communication between the ground system and unmanned aerial vehicles (UAV). Previous research has focused on enabling aerial data-centric smart services while integrating the benefits of aerial objects such as UAVs in hostile and non-hostile environments. Quality of service (QoS) provisioning in UAV-assisted communication is a challenging research theme in aerial ad-hoc networks environments. Literature on aerial ad hoc networks lacks cooperative service-oriented modeling for distributed network environments, relying on costly static base station-oriented centralized network environments. Towards this end, this paper proposes a quality of service provisioning framework for a UAV-assisted aerial ad hoc network environment (QSPU) focusing on reliable aerial communication. The UAV’s aerial mobility and service parameters are modelled considering highly dynamic aerial ad-hoc environments. UAV-centric mobility models are utilized to develop a complete aerial routing framework. A comparative performance evaluation demonstrates the benefits of the proposed aerial communication framework. It is evident that QSPU outperforms the state-of-the-art techniques in terms of a number of service-oriented performance metrics in a UAV-assisted aerial ad-hoc network environment

Connectivity Analysis in Vehicular Ad-hoc Network based on VDTN

In the last decade, user demand has been increasing exponentially based on modern communication systems. One of these new technologies is known as mobile ad-hoc networking (MANET). One part of MANET is called a vehicular ad-hoc network (VANET). It has different types such as vehicle-to-vehicle (V2V), vehicular delay-tolerant networks, and vehicle-to-infrastructure (V2I). To provide sufficient quality of communication service in the Vehicular Delay-Tolerant Network (VDTN), it is important to present a comprehensive survey that shows the challenges and limitations of VANET. In this paper, we focus on one type of VANET, which is known as VDTNs. To investigate realistic communication systems based on VANET, we considered intelligent transportation systems (ITSs) and the possibility of replacing the roadside unit with VDTN. Many factors can affect the message propagation delay. When road-side units (RSUs) are present, which leads to an increase in the message delivery efficiency since RSUs can collaborate with vehicles on the road to increase the throughput of the network, we propose new methods based on environment and vehicle traffic and present a comprehensive evaluation of the newly suggested VDTN routing method. Furthermore, challenges and prospects are presented to stimulate interest in the scientific community

Towards video streaming in IoT environments: vehicular communication perspective

Multimedia oriented Internet of Things (IoT) enables pervasive and real-time communication of video, audio and image data among devices in an immediate surroundings. Today's vehicles have the capability of supporting real time multimedia acquisition. Vehicles with high illuminating infrared cameras and customized sensors can communicate with other on-road devices using dedicated short-range communication (DSRC) and 5G enabled communication technologies. Real time incidence of both urban and highway vehicular traffic environment can be captured and transmitted using vehicle-to-vehicle and vehicle-to-infrastructure communication modes. Video streaming in vehicular IoT (VSV-IoT) environments is in growing stage with several challenges that need to be addressed ranging from limited resources in IoT devices, intermittent connection in vehicular networks, heterogeneous devices, dynamism and scalability in video encoding, bandwidth underutilization in video delivery, and attaining application-precise quality of service in video streaming. In this context, this paper presents a comprehensive review on video streaming in IoT environments focusing on vehicular communication perspective. Specifically, significance of video streaming in vehicular IoT environments is highlighted focusing on integration of vehicular communication with 5G enabled IoT technologies, and smart city oriented application areas for VSV-IoT. A taxonomy is presented for the classification of related literature on video streaming in vehicular network environments. Following the taxonomy, critical review of literature is performed focusing on major functional model, strengths and weaknesses. Metrics for video streaming in vehicular IoT environments are derived and comparatively analyzed in terms of their usage and evaluation capabilities. Open research challenges in VSV-IoT are identified as future directions of research in the area. The survey would benefit both IoT and vehicle industry practitioners and researchers, in terms of augmenting understanding of vehicular video streaming and its IoT related trends and issues

Optimal configuration of active and backup servers for augmented reality cooperative games

Interactive applications as online games and mobile devices have become more and more popular in recent years. From their combination, new and interesting cooperative services could be generated. For instance, gamers endowed with Augmented Reality (AR) visors connected as wireless nodes in an ad-hoc network, can interact with each other while immersed in the game. To enable this vision, we discuss here a hybrid architecture enabling game play in ad-hoc mode instead of the traditional client-server setting. In our architecture, one of the player nodes also acts as the server of the game, whereas other backup server nodes are ready to become active servers in case of disconnection of the network i.e. due to low energy level of the currently active server. This allows to have a longer gaming session before incurring in disconnections or energy exhaustion. In this context, the server election strategy with the aim of maximizing network lifetime is not so straightforward. To this end, we have hence analyzed this issue through a Mixed Integer Linear Programming (MILP) model and both numerical and simulation-based analysis shows that the backup servers solution fulfills its design objective

The project TEMPUS — ECOMMIS («double-level training programs of e-commerce developing the information society in Russia, Ukraine and Israel») was launched in October 2011, and belongs to a class of joint projects to develop new courses and courses for bachelor’s and master’s degrees. The project consortium involves 12 universities from Germany, the Netherlands, Lithuania, Israel, Russia and Ukraine. The main objective of the project is to develop and implement new academic courses and areas of study, taking into account the current status and trends of economic development and the specific requirements of the labor market on the basis of cooperation between universities in different countries. The main feature and complexity of the project academic content of is that e-commerce as an academic concept is absolute new and it appeared just only in the last decade. It is a new interdisciplinary field of knowledge, which is located at the intersection of economics and computer science and it is not covered by the classical training courses in economics and computer science technology. The aspects of national and international law in connection with the growth of international trade, economic cooperation and the development of new Internet based technologies should be taken into account. For the project’s period of three years on the basis of international cooperation the following results were obtained: 11 Preface 1) The analysis and modernization of existing curricula in the field of e-commerce were carried out; 2) new training modules with the introduction of the European creditmodular system of accumulation and transfer transcripts units ( ECTS ) were developed; new modules and courses: e-commerce, electronic payment systems; Internet trading in the financial markets and the stockmarket systems; Information systems for financial analysis and investment; Information systems for business process modeling; corporate information systems and portals; Customer-oriented systems; Internet Marketing; electronic systems for document management; legal aspects of e-commerce; advanced course security for e-commerce were introduced; 3) two international online games to enhance practical skills in the field with online marketing and online trading were developed and conducted among university students; 4) skills training courses e-commerce for various social groups (students, housewives, pensioners, unemployed) were developed and tested; 5) business offices, e-commerce were established to strengthen cooperation between the universities in the labor market and to create the conditions of commercialization of the project results after the end of financial support from the TEMPUS Program. 6) textbooks on the topic of the project were developed and published. In May — July 2013. 62 teachers targeted universities in Israel, Russia and Ukraine received intensive training in the field of e-commerce in three European universities: FONTYS (NL), TU Berlin (DE), VGTU ( LT ). From October 2013 in target universities of Israel, Russia and Ukraine students’ training began on the courses developed in the framework of the new training courses and modules with using computer classes, equipped in accordance with the project plan with new hardware and software tools. The final stage of the project was intended to develop a five-year detailed plan for sustainable development of the results. Such plan that includes coordinated action to disseminate best practices, development of new joint courses for graduate and post-graduate students, scientificmethodical conferences, joint publications will support the further dynamics of the activities involved universities. Joint work on the implementation of the project ECOMMIS led to the emergence of sustainable professional relationships between organizations in the consortium as the training of new qualified professionals, as well as in the field of scientific and methodological developments. This is confirmed by the present collective monograph E-commerc
