Talk by Dr. Vlado Handziski on 30.04.2014 at 15:00h - Towards Testbed Infrastructures for the IoT Age, the TWIST Way

Abstract

Over the past decade, the TKN Wireless Indoor Sensor network Testbed (TWIST) has been used to collect experimental data for more than a hundred scientific publications, becoming a valuable asset for the sensornets research community. While TWIST and similar testbeds around the world have helped push the boundaries of sensornet experimental research, the emerging fields of cyber-physical systems and internet-of-things impose new requirements on the experimental infrastructure that are not easily met by the old testbed designs. To address these needs, TWIST has recently been extended with components for actuation, mobility, RF interference generation and monitoring, cloud integration and federation with other testbeds. In the talk I will discuss our experiences with TWIST, the motivation behind the new extensions, and the challenges associated with designing convenient testbed control APIs for their services. Finally, I will illustrate the capabilities of the new design in supporting complex experimental scenarios by presenting results from measurement campaigns for benchmarking RF-based indoor localization systems.

Bio:

Dr.-Ing. Vlado Handziski is a senior researcher in the Telecommunication Networks Group at the Technische Universität Berlin, where he coordinates the activities in the areas of sensor networks, cyber-physical systems and internet of things. He received his doctoral degree in Electrical Engineering from TU Berlin (summa cum laude, 2011) and his M.Sc. degree from Ss. Cyril and Methodius University in Skopje (2002). Dr. Handziski's research interests are mainly focused on testing and software architecture aspects of networked embedded systems.  He has lead testbed infrastructure activities in several large European research projects like Embedded WiSeNts, CONET, EVARILOS, EIT ICT Labs. He is leading developer of TinyOS, one of the most popular operating systems for sensor networks, and chief architect of the TWIST testbed. At TU Berlin, he teaches the master-level courses on "Ad Hoc and Sensor Networks" and "Networked Embedded Systems". Dr. Handziski is member of IEEE and ACM.
