This article is devoted to the development of the scrambler circuit. Nowadays, new WiFi standard IEEE 802.11 is being put into operation, so that there is a huge need in modern, energy-efficient algorithms, which will be used in the data transmission. Consequently, some of the scrambler circuits, which could be implemented for the IEEE 802.11 standard are described with its comparison. In addition, an example in Python is given for readers to use it in their researches.
This article provides an overview of the existing problems in the construction of wireless sensor networks (WSN), in particular the problem of energy efficiency of the system. In many cases, the WSN is set in places where the connection to the stationary power sources is difficult or impossible. Such situations require the use of autonomous energy sources: traditional (batteries) or alternative (solar panels, wind generators, etc.). Due to limitations in the available system power there is obvious need in efficient use of available energy resources.
