Abstract:
The Internet of Things (IoT) concept has gained considerable importance in industry and academia in the last few years. The possibility of interconnecting a huge number of sensors and other devices allows the creation of various new applications. This is possible thanks to the advances in device technologies and communication protocols, which enable such interconnections. We consider Wireless Sensor Networks (WSN) as a subset of the IoT, representing the type of networks that rely on mesh topologies and multi-hop communication. The communication pattern of many nodes transmitting data to one sink/gateway node poses unique challenges. Application or device misbehaviour at the protocol or network level can diminish or totally eliminate a network's capacity to perform its intended function. This talk will initially present a line of research that addresses performance control in WSNs by analysing causes of overload (usually congestion) and proposes three solutions based on alternative path creation. We will continue by identifying other parameters affecting reliability and we will devote considerable time discussing ways of detecting network-layer routing problems and other faults in WSNs and IoT networks. The talk will also present our current activities towards fault recovery using mobile node solutions.

Short Bio:
Dr. Vasos Vassiliou is an Assistant Professor at the Department of Computer Science of the University of Cyprus where he is co-directing the Networks Research Laboratory. He is also the Team Leader of the Smart Networked Systems Research Group at the newly established Centre on Interactive Media, Smart Systems and emerging Technologies (RISE). Dr. Vassiliou serves as the Chair of the Board of Directors of CYNET, the National Research and Educational Network. He completed his undergraduate studies at the Higher Technical Institute (H.N.D in Electrical Engineering, 1993) and the University of South Florida (B.Sc. in Electrical Engineering, 1997) and his postgraduate studies at the Georgia Institute of Technology (M.Sc. in Electrical and Computer Engineering, 1999, Ph.D. in Electrical and Computer Engineering, 2002). His research interests lie in the areas of Protocol Design and Performance Control aspects of Networks; in particular: Internet of Things, Security, Mobility Management, QoS Adaptation and Control, and Resource Allocation and Management Techniques.
