НАУЧНО-ПРАКТИЧЕСКАЯ КОНФЕРЕНЦИЯ «30-ЛЕТИЕ НЕЗАВИСИМОСТИ КАЗАХСТАНА: ДОСТИЖЕНИЯ И ПЕРСПЕКТИВЫ» Figure 1 – «Architecture of Wireless Sensor Networks» The fifth-generation networks are heterogeneous because they combine many different networks, from
traditional mobile and fixed public networks to sensor and flying networks. The main distinguishing properties
of the new generation networks are ultra-density and ultra-low latency.
The superdensity of the network is associated with the rapid increase in the number of Internet of Things,
which is now considered at the level of the estimated 50 trillion. The implementation of such properties is
possible using D2D technology, where interactions between two devices, for example, user terminals and
the Internet of Things, are possible without the participation of a base station. Such interaction, in terms of
electricity consumption by the network, will be more efficient.
The problem of energy saving takes one of the first places in the design of modern WSNs. Recently, a family
of LPWANs (Low Power Wide Area Networks) standards has been developed for the low power networks
operating in large-scale networks over long distances. The use of LPWANs technology in the fifth-generation
networks is especially important for the fast-moving objects in the base station area.
Ultra-low latency is associated with the Tactile Internet, where the connection delays are microseconds. So,
for example, the range of networks for the provision of Tactile Internet services, with a delay limited to 1ms,
taking into account the two-way delay, for a transmission system with a high bandwidth is limited to about 50
km. That is, the data centers located in macro areas should be closer to the center of such a range.
Figure 2 shows a multi-layer cloud infrastructure system for next-generation communication networks,
which consists of five layers. At the micro cloud level, the users of smartphones, laptops, robots, Internet of
Things, etc. are placed. In the mini cloud, there are base stations and elements of optical access networks. In the
macro cloud, the cores of the operator's network are located, and the resources of the world's largest companies
are in the remote cloud.
