Abstract (en)
Some of the structures of smart cities, whose operation is based on
various autonomous sensors, are intelligent transport systems and
systems for monitoring environmental parameters.
Quantitative and qualitative detection of vehicles is one of the basic
operations of intelligent transport systems. The dissertation describes
the process of designing a magnetic field generator in two different
ways, which reconstructs the vehicle's magnetic signature in order to
simulate the traffic flow and test the correctness of the vehicle's
detector. The design of the parameters of the coil used to generate the
magnetic field is performed analytically and numerically.
Also, a vehicle detector based on a sensor for measuring the magnetic
field, based on a finite state automaton algorithm implemented using
a microcontroller, was designed.
Another example of an autonomous sensor implemented in the
dissertation is a sensor node for air quality monitoring. At the same
time, energy consumption was optimized using the TEEN routing
protocol and the principle of determining ST limit values was
presented. A sensor node for temperature measurement with direct
communication with the server by implementing the MQTT protocol
was realized.
The autonomy of the sensor is reflected, first of all, in its independent
power supply, in the implementation of which supercapacitors play a
significant role. The dissertation presents the experimental results of
comparing the efficiency of supercapacitor charging in different ways
using low-power solar cells.
In addition to the autonomous power supply of individual nodes,
within the sensor network it is necessary to ensure an appropriate
level of security when sending data, for which encryption algorithms
are most often used. A performance comparison between the
hardware and software implementation of the AES encryption
algorithm within the sensor node was performed.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
