Anthony Tzes is Professor and Head (2009–11) of the Electrical & Computer Engineering Department of the University of Patras (UPAT) in Greece. He is a graduate of UPAT (85) and has received his doctorate from the Ohio State University (90). From 1990 till 1999 he was with NYU Polytechnic. His research interests include Networked Controlled Systems, MEMs, Robotics, Mechatronics, Adaptive Control, Neural Networks and Fuzzy Logic Applications for Intelligent Transportation Systems, Adaptive Fuzzy Control, Instrumentation Embedded Systems, System Identification and Signal Processing. Prof. Tzes has been a committee member of the Advanced Traffic Management Systems of the ITS-America organization, and has received research funding from various organizations including NASA, and the National (US) Science Foundation, the European Union (FP6), and the European Space Agency (ESA). He has been the Chairman of IEEE’s Control Systems Society Greek Chapter, a member of the national (Greek) committee of the European Control Association (EUCA), member at several committees of the International Federation of Automatic Control (IFAC), and until recently the national representative to EU’s FP7’s thematic area “Regions of Knowledge, Research Potential and Coherent Development of Policies”. He has served in various positions (Program Chairman (MIM ’00), Organizing Committee Chairman (ECC’07)), and as IPC-member at several international conferences. He has over 10 years of experience as the director of the Instrumentation and Control Laboratory at NYU Polytechnic focusing on smart sensors and self-tuning systems. Concurrently, he served as the principal investigator of the Urban Intelligent Transportation Systems Center in New York, NY. While in Greece, he is the leader and principal investigator of the “Applied Networked micro Mechatronics Systems group”. He has authored more than 50 (125) papers published in international technical journals (conferences) and has served in the editorial board of several journals (e.g. IEEE Control Systems Magazine, Circuits Systems and Computers). His current research is funded by several national (Greek) and EU-projects.

N2 - Wireless Sensor Networks (WSNs) have an ever increasing variety of multimedia based applications. Ιn these types of applications, network nodes should ideally maximize QoS and minimize energy expenditures in video communication. This article presents PEMuR, a novel dual scheme for efficient video communication, which aims at both energy saving and high QoS attainment. To achieve its objectives, PEMuR proposes the combined use of an energy aware hierarchical routing protocol with an intelligent video packet scheduling algorithm. The adopted routing protocol enables the selection of the most energy efficient routing paths, manages the network load according to the energy residues of the nodes and prevents useless data transmissions through the proposed use of an energy threshold. In this way, an outstanding level of energy efficiency is achieved. Additionally, the proposed packet scheduling algorithm enables the reduction of the video transmission rate with the minimum possible increase of distortion. In order to do so, it makes use of an analytical distortion prediction model that can accurately predict the resulted video distortion due to any error pattern. Thus, the algorithm may cope with limited available channel bandwidth by selectively dropping less significant packets prior to their transmission. Simulation results demonstrate the effectiveness of the proposed scheme.
