Models, protocols, algorithms in networked systems
Research and Development Objectives
The purpose of conducted research is to create realistic models of networked systems and to design and analyze the properties of protocols and algorithms that govern the resource allocation and information exchange in distributed architectures.
In recent years, one may observe significant progress achieved in the development of applications combining data transmission networks, distributed and automatic control systems, e.g., intelligent transport, or Internet of Things. The undertaken research work encompasses the analysis of existing networked systems and design of new protocols and algorithmic schemes. The objective is to ensure an adequate performance level despite inopportune phenomena obstructing the physical system implementation, e.g., delay, disturbances, or data loss in network transmission. Both formal – incorporating the advanced tools of control and optimization theories – and practical – involving real devices and data transfer networks – activities are undertaken to meet the current challenges in the field.
