Internet of Things Laboratory Test Bed

The Internet of Things (IoT) is the new concept for the network development. The enormous number of the things requests to investigate the networks interoperability as one of the important parts of IoT implementation. The competent testing is the general matter for networks interoperability support. So, the IoT implementation requests the test bed creation. The test bed features in the IoT Lab at the State University of Telecommunication in Saint Petersburg are considered in the paper. The testing examples are given. The IoT test bed using for students education is considered too.

Model networks for Internet of Things and SDN

The Model Networks have found widespread implementation in testing NGN-services. Currently, in a telecommunication sphere the concept of the Internet of Things (IoT) is widely recognized as a key. In this connection, it is advisable to use an approved approach for testing devices and applications of the Internet of Things based on model networks. The article presents the structure of the model network, created on the basis of the Laboratory of the Internet of Things in the State University of Telecommunication and a description of features of the network for a comprehensive research of the Internet of Things.

Comprehensive SDN Testing Based on Model Network

Software-defined networking (SDN) can significantly automate and facilitate network management by allowing their programming. In this paper we show the SDN concept, method of testing, and the main characteristics of the SDN controller. The study based on the model network in the laboratory high-speed backbone networks DWDM and programmable networks SUT. The paper presents results of a collaborative functioning of SDN and DWDM-network. In this paper we created graphical interface over Cbench and added several advanced features in C++, also conducted stress testing SDN controllers.

Multilevel cloud based Tactile Internet system

Far from the traditional Internet in which audio and visual senses can be transferred, the Tactile Internet will introduce a way for transferring touch and actuation in real time form. However, the fifth generation of the mobile cellular system (5G) will be a great support for realizing Tactile Internet, the 1 ms round-trip-delay still a great challenge in the way of the Tactile Internet realization. Mobile edge computing (MEC) is a solution introduced to reduce the round trip latency and provide a way for offloading computation from the cellular network. In this paper we introduce a novel approach toward a multi-level cloud based cellular system, in which the small cells are connected with micro-cloud units with small capabilities to present the edge computing facilities. The micro-clouds are connected to mini-cloud units which have greater capabilities. The core network cloud connects the mini-clouds in the whole system. Introducing more levels of clouding reduces the round trip latency and the network congestion.

Software-defined architecture for flying ubiquitous sensor networking

The paper describes a flying ubiquitous sensor network (FUSN) and the method of interaction UAV network (flying segment) and the terrestrial segment. It is shown that the main problem of the interaction is a significant difference between the motion characteristics of the objects of terrestrial and flying segments of FUSN. It is caused by the fact that the sensor node can be in communications range of the UAV flying segment for a limited time. It is proposed to use the additional nodes that perform the routing control function (role SDN controllers). When placing the nodes on UAVs, there are the additional options of the network structure and condition monitoring of communication channels, the localization of its components, assessing the characteristics of movement, getting forecasts of network structure changes. Organizations of flying ubiquitous sensor network, which is based on SDN architecture, improves its resistance to changes in the structure, reduces the amount of routing traffic due to its location within the same management cluster.

Connectivity of VANET Segments Using UAVs

The main topic of the researches is VANET (Vehicle Ad-hoc Network). VANET is a peer-to-peer network based on IEEE 802.11p standards and group standards IEEE 1609 Wireless Access in Vehicular Environments (WAVE). Another current line of research is the UAVs. In 2015, the scientific works, oriented to research of a possibility of UAVs use for the VANET networks, began to appear. The scientific works present issues concerning connection of separately located network nodes by means of UAVs.

Flying ubiquitous sensor networks as a queueing system

The Flying Ubiquitous Sensor Networks (FUSN) includes two segments: ground and flying. The ground segment is the traditional ubiquitous sensor network (USN) with field or mobile sensor nodes. The flying segment represents the one or more small Unmanned Aerial vehicles (sUAV) which are equipped with sensor nodes as well. The sUAV can collect data from ground sensor fields. Furthermore, the sUAV can be a temporary cluster head for ground sensor nodes during this collecting. The sUAV is considered as the queuing system in the paper. Two general models are analyzed. There are the ground segments of sensor nodes with known coordinates on the first model. The sensor nodes with unknown coordinates are on the second model. The schedule collection procedure is proposed for the first model. The distribution function for requests number from sensor nodes is defined for the second model.

Live substance in cyberspace — Biodriver system

The internet of bio-nanothings has become an important research topic last years, because of the broad opportunities for the new applications that it provides. The key problem which should be solved is a creation of its-bio interface for integration of the living substance into the cyberspace. This paper formulates the general conjugation principle of a living substance with an info-communication system, and develops an integrated system enabling quantitative and qualitative measurements of the certain processes occurring in living organism with a feedback. The study reveals the design of an integrated system and the way of interaction between components can be organized. Further, the paper reviews the medical health status indicators that can be used in an integrated system for analyzing the processes occurring in the body. Then, the possible applications as well as the open research problems are presented.

Analysis of delays in medical applications of nanonetworks

Nanonetworks is the innovative direction of Internet of Things (IoT). Nanonetworks technologies promises extensive opportunities for creating innovative applications and it is attracts researchers from different fields of science. Healthcare is one of the fields in which nanonetworks promise technological spurt. For the effective functioning of the medical applications of nanonetworks it is necessary to provide high quality of service (QoS) for end-to-end traffic. In this article we analyzed network delay — one of the most important QoS parameters. Maintenance of low delays especially important for real-time medical applications. The article examines the factors that defines requirements to delay for real-time medical applications as well as components of delay at various levels of the network.

False clouds for Internet of Things and methods of protection

This paper describes the results of a full-scale experiment, in which the data from a Thing of Internet is redirected to a false cloud. This paper also suggests methods of protection which can prevent this type of an attack and secure the connection between a Thing of Internet and Public communication network - Cloud service.
