Sensor information system
The main research objectives are: sensor's data acquisition, information processing and process control, sensor - information systems, connection between distributed systems and microprocessor controllers. The research focus is on the relation between different communication interfaces/ environments and specially on the connection between wireless sensor networks and conventional systems/environments, and on development of microprocessor distributed systems for information processing and control. The activity is directed to design of network systems embracing research apparatus as end-devices with wireless communication between them; research on ZigBee technology implementation for control of swarm of mobile devices; extension of wireless sensor networks application - work on SMART METERING direction and development of wireless sensor networks for home automation and consumption monitoring; realization and integration of wireless abilities with industrial application and process control.

Dependable, secure, and resilient computer systems and networks
Modelling fault-tolerant systems and networks; developing simulation models of real-time process control systems, study of the quality of service of communication networks. Recently, the efforts are directed towards research in the fields of information security and the development of the concept of resilience: study of future and emerging information security threats, developing methods and models to decrease vulnerabilities in systems and networks, and improving networks' protection against attacks (e.g., in wireless sensor networks), implementation of security tools in control systems operating in open network environment. Researches continue with the development of the dependability and security model with new properties, such as: self-healing, adaptation to changes, as well as use of cognitive/artificial intelligence technologies, aiming at more efficient dealing with future challenges, i.e., use and implementation of the resilience approach.
