CV
Corinna Schmitt was born in Munich (Germany). She studied Bioinformatics at the Eberhard-Karls Universit?t Tübingen (Germany) until 2006 and graduated with the diploma degree. After one year work at the Fraunhofer Institute in Stuttgart dealing with cluster analysis of cancer data she started her Ph.D. For the Ph.D. she moved back to Munich and joint the Technische Universit?t München (TUM). Currently she is working at the Department for Computer Science at the chair Network Architecture and Services by Prof. Dr.-Ing. Carle. During her research she focus on Wireless Sensor Network for establishing an efficient data transmission protocol with additional features fur aggregation, secure transmission and data import/export. She planned to submit here Ph.D. thesis in summer 2012.
Abstact: " TinyIPFIX - An efficient Data Transmission Protocol for Wireless Sensor Networks "
When Wireless Sensor Networks (WSNs) become part of a larger cyber-physical system their communication is even more aimed towards other machines than in standalone deployments. Cyber-physical systems are gaining commercial momentum in areas such as building monitoring or intelligent home automation. Users wish to easily deploy hardware from different manufacturers at different times, ensuring interoperability and avoiding the need for exhaustive configuration and set-up. Therefore, the need for an efficient application layer protocol for machine-to-machine communication in and across the boundaries of WSNs arises. Such a protocol must be designed with the aspects of Metrology, Syndication, Resource Efficiency and Scalability in mind, and additionally under the usage of well proofed standards in common Peer-to-Peer-Networks. Those ideas are issued with our implementation of TinyIPFIX, an adaption of the IP Flow Information Export (IPFIX) protocol. For application purposes a home scenario is assumed. The TinyIPFIX protocol is a modular implementation which allows adaption to modified scenarios or hardware with less manual input. As an operating system TinyOS 2.x with BLIP is used over UDP. This talk shows how IPFIX is adapted to WSN requirements and how to improve the functionality of TinyIPFIX by adding aggregation functionality to the established system. The solutions we developed covers message aggregation and data pre-processing functionality. Currently a secure data transmission between a special cluster head (including a Trusted Platform Module chip) with the central data sink is established. This communication part works via a DTLS handshake mechanisms. Currently on going work deals with import/export features to external data analysis tools and a handsome GUI. The already established network was tested partly on the Harvard Motelab in California (USA) and complete tested on a local testbed with around 40 sensor nodes including IRIS, TelosB and OPAL nodes.
