The ongoing shift toward renewable energy and increased electrification poses significant challenges to existing communication infrastructures, particularly in smart-grid environments. Radek Možný’s research demonstrates that current and upcoming cellular IoT technologies require targeted optimization to effectively support smart-grid applications.
His extensive measurement campaigns reveal performance bottlenecks under realistic, heavy-load scenarios typically encountered in urban and industrial contexts.
Možný’s findings highlight that although NB-IoT provides strong coverage, it struggles to meet the demands for high-throughput and low latency in dense network deployments.
“Without proper optimization, neither current implementations nor anticipated technological advancements can reliably meet the rigorous operational demands of smart-grid systems,” Možný says.
To address these challenges, Možný develops novel optimization strategies that improve resource allocation, message distribution, and traffic management, significantly enhancing network performance.
Solutions for network stability and reliability
Central to Možný’s thesis are newly developed mathematical models and simulation tools designed for performance evaluation and optimization of smart-grid communication networks. These models identify and address performance bottlenecks, offering practical methods for optimizing the distribution of data transmissions between multiple radio technologies (Multi-RAT approaches).
His results demonstrate the capability to drastically reduce latency while significantly increasing system reliability and efficiency.
“By balancing the network load effectively between NB-IoT and LTE-M technologies, the research paves the way for scalable and resilient smart-grid deployments,” Možný comments.
Možný’s findings not only improve network stability under varying traffic loads but also support regulatory compliance, particularly meeting stringent EU guidelines for smart metering and infrastructure reliability.
Možný's dissertation outcomes have been rigorously peer-reviewed and disseminated through multiple scientific publications, including renowned journals and international conferences such as Elsevier Internet of Things, IEEE Internet of Things Journal and IEEE Wireless Communications and Networking Conference.
Radek Možný combines extensive industrial expertise with rigorous academic research. Previously, he held a network measurement and optimization position at a major telecommunications operator.
