The focus of my research lies with efficient and secure communication in the Internet of Things (IoT) or IP-enabled Wireless Sensor Networks (WSNs) as a subset thereof. Specific topics include:

  • Power Line Communication in Industrial Automation
    Power lines are an ubiquitous medium for communication that is shaping up to play an important role in the future of the smart grid and smart home. Emerging standards, such as IEEE 1901, and commercially available devices implementing them are increasing industry interest in this technology  Application fields such as industrial building- or process automation have more stringent requirements for quality of service and predictability. My current research at the Technische Universität München is focused on this field of study.
  • Security for the Internet of Things
    Standard-based protocols are accelerating IoT research and enabling new industry applications. However, a standard based security solution is still missing from an open protocol stack in this area. We provide a first implementation and thorough evaluation of the security protocol DTLS in an IEEE 802.15.4 network to help fill this void. [Read on]
  • An Efficient Machine-to-Machine Communication Protocol for WSNs
    In a general M2M setting, the data from an data exporter has to be syntactically and semantically understood by the collector of this data. The protocol employed for this task must have low network and computational overhead. Additionally, a minimal level of configuration required by the human user of the system should be required. Our solution adapts the Internet Protocol Flow Information Export protocol (IPFIX) to achieve these goals in the WSN context. [Read on]
