—The increasing share of renewables creates new challenges for the existing electrical grid. To deal with these challenges, various efforts are being made to transform the existing power grid into a so-called smart grid. Part of this process is the deployment of an advanced metering infrastructure, which provides novel high-frequency two-way communication… (More)

Abstract—Today's street traffic is still largely inefficient. Over-burdened roads lead to congestions, accidents and unnecessary pollution. The increasing interconnection of traffic participants into… (More)
Smart Metering is one of the key components of upcoming Smart Grids. As with every new technology, there is no consensus on how it should be done and what dangers lie in its widespread application. Besides organization and management of data transfers and storage, the privacy of customers is also a major concern. A multitude of solutions exists, each… (More)
—Smart metering is an essential part of the future smart grid but causes privacy issues by collecting sensitive data from households with a high temporal resolution. Peer-based privacy mechanisms can solve this problem through privacy-aware aggregation. The SMART algorithm, originally proposed for wireless sensor networks, is a lightweight approach to this… (More)
