ARCHITECTURE OF ADAPTIVE WIRELESS LOCAL NETWORK FOR CONTROLLING OBJECTS AND DEVICES

Khoroshko Maxim B., Skorikov Ivan O.

The use of high-speed multi-hop wireless networks is becoming increasingly relevant as a new wave of different wireless devices are being researched and developed. This is particularly relevant for public safety, surveillance and monitoring applications where streaming multimedia data is constantly being generated and must be made available to users in real time. High-bandwidth communication techniques, such as IEEE 802.11s-based wireless mesh networks, can provide low-cost and easy-to-deploy solutions that are scalable and suitable for these services. However, there is a parallel issue of adapting wireless networks to inconsistent environmental conditions as well as to changing user requirements. Equally important is the challenge of minimizing power consumption while meeting quality constraints during wireless network operation. Particular emphasis must be placed on the fact that these adaptations must be performed at runtime in order for the network to operate efficiently in an ever-changing environment. In view of the noted, the paper deals with the issues related to the study of the peculiarities of designing the architecture of an adaptive wireless local area network for controlling objects and devices. As an object of research the task of controlling technological equipment, objects and devices within the framework of IoT technology realization was considered. Special attention in the article is paid to the equipment of base stations, which are divided into two types, depending on computing capabilities. It also describes the peculiarities of modem design, taking into account the channel for which it will be used. As a result, the architecture of adaptive wireless local area network is presented. Its distinguishing feature is the presence of a new wireless switch that allows reconfiguration of network topologies and frequency ranges, adapting to the changing requirements of indoor traffic. The new architecture requires less infrastructure, reduces power consumption, and reduces network deployment and maintenance costs.
