DESIGNING WIRELESS NETWORKS FOR MOBILE OBJECTS

Skorikov Ivan O., Khoroshko Maxim B.

In the last decade, mobile communication has developed a lot, allowing you to exchange data with anything, anywhere and anytime. The use of such communication systems in vehicles is a reality today. As a result, movable objects become sensor-rich platforms capable of responding to changes in their environment. As a consequence, wireless communication infrastructure plays an important role in providing information access to vehicles as well as downloading environmental data. The consequence of the development of wireless technologies is the formation of intelligent transportation systems, where vehicles are intelligent objects exchanging data with each other using an intelligent approach. This new concept of data exchange between vehicles, sensors and infrastructure opens up many opportunities such as: driver safety, tracking of incidents on the road, timely response to abnormal situations. At the same time, in order to enjoy these benefits, it is an open question to choose the most reliable wireless network architectures for mobile objects. Taking into account the noted, the article is devoted to the study of features and key points of designing wireless networks for mobile objects on the example of motor vehicles. In the process of the study the results of comparison of VANET and SDN-IoV are presented. Also, the requirements to be met by wireless networks for mobile objects are formulated. An author's approach to wireless network architecture is proposed, which is based on software-defined networks and the Internet of Vehicles. The block diagram of the algorithm of adaptive broadcasting of traffic signals is formalized separately and the principle of operation of the proposed architecture is presented on a practical example. In addition, the functionality that the node layer in the network must support is emphasized. The problems that the network protocol has to face are highlighted. In order to solve these problems it is proposed to use a network layer that implements a localized routing mechanism.
