Abstract

In various applications of the Internet of Things, one of the basic elements of architecture is wireless networks in the nodes of which sensors are located to collect heterogeneous information, determined by the type of application. One of the ways to extend the duration of uninterrupted network operation is to combine sensors into clusters. Many sensors in wireless sensor networks (WSNs) operate in periodic mode, alternating communication sessions with periods of operation waiting.

Sensors usually have autonomous power supply from accumulators or batteries, ...
