About

Charalambos Sergiou is a researcher whose work lies at the critical intersection of Wireless Sensor Networks (WSN) and the Internet of Things (IoT), focusing on the strategic deployment and reuse of mobile nodes to solve fundamental network challenges. His primary research addresses persistent problems like path disconnections, network segmentation, node faults, and security attacks—issues that can cripple the reliability of modern distributed systems. Sergiou’s major contribution is the development of intelligent algorithms and energy-efficient mechanisms that leverage mobile nodes not just as passive sensors, but as active, reconfigurable assets. His most-cited paper, "A Node Placement Algorithm Utilizing Mobile Nodes in WSN and IoT Networks" (2022, 9 citations), introduces a novel placement strategy to dynamically repair and optimize network topology. Complementing this, his work on "Energy Efficient Mechanism for Reusing Mobile Nodes" (2021, 3 citations) tackles the critical challenge of power conservation, ensuring that mobile nodes can be redeployed without exhausting their limited energy budgets. By pioneering methods that transform mobile nodes from a luxury into a practical, energy-aware tool for network resilience, Sergiou is helping to build more robust, self-healing IoT and WSN infrastructures for the future.
