Course detail

Wireless Sensor Networks

FEKT-MPA-SSYAcad. year: 2024/2025

The course focuses in practice and provides students with knowledge and experience in the field of wireless sensor networks and their applications. Students will learn to work with wireless sensor units equipped with microcontrollers and radio chips during the semester, using the IEEE 802.15.4 communication protocol, protocols using this standard, and the Bluetooth LE protocol. Part of the subject is the design and implementation of their own protocol, implementation of the wireless sensor network and its integration into the Internet of Things network. In the last part of the course the students will be acquainted with the possibilities of sensor unit design, power supply and sensing of physical quantities sensors.

Rules for evaluation and completion of the course

Up to 100 points can be earned while studying the course. Up to 30 points can be obtained as part of the laboratory exercises for defending the project. The scourse ends with an exam, where up to 60 points can be obtained for the written part and 10 points for the oral part. 

The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.

Aims

This subject is aimed at making the students familiar with the representative sensor systems, with their components and their practical exploitation. The students will obtain a fundamental theoretical orientation in the area of modern sensor technology and they will acquire some skills in design procedures by way of solving practical examples.
The students obtain knowledge about the wireless sensors, which are used in the home, building and transport automation- They will work with the Zigbee protocol and Atmel wireless nodes.
