the paper briefly describes the specifics of precision agriculture from the point of view of data needs and the possibility of providing such data. It points to the most convenient and efficient form of collecting the necessary data using drones. Specific drone characteristics are recorded/discussed in order to facilitate selecting the right one according to the farmers' heterogeneous requirements regarding the data collection on their crops. Selecting the appropriate drone for the specific needs of farmers is carried out by a multi-criteria decision-making software.

Wireless Sensor Networks (WSN) and related technologies have the important impact nowadays. These technologies have variety of applications, and they are key enabling technologies of IoT (Internet of Things). ZigBee standard is the most common WSN technology. Its importance and expansion, as a widely used technology in many different areas, influence the importance of including ZigBee technology in courses at university. This paper presents the software application and related hardware platform designed to be used by the students to measure and analyze the performances of ZigBee network in design and pre-implementation process. The presented application can be used during the classes of Communication Systems and Computer Network Courses for ZigBee traffic and packet analyses. In addition, this application can be used for researching in the field of wireless sensor networks, ZigBee and other similar popular technologies such as Bluetooth Low Energy, IEEE 802.15.4, etc. The supporting platform for this application and experiment for its evaluation are also presented in this paper.

This paper puts in the focus two important segments of information and communication technology. The first segment is monitoring of data centers and the second one is usage of open source hardware. The reason for combining these two segments is effort to explore the efficiency of open source hardware platforms in these environments. The advantages of open source hardware platform as a tool for rapid prototype development and combination of variety of technologies were taken as the main starting point for this research. This paper describes the model for data center temperature monitoring with the usage of open source hardware. The prototype system is partially implemented in accordance with the presented model.
