Named Data Networking (NDN) is one of five projects funded by the U.S. National Science Foundation under its Future Internet Architecture Program. NDN has its roots in an earlier project, Content-Centric Networking (CCN), which Van Jacobson first publicly presented in 2006. The NDN project investigates Jacobson's proposed evolution from today's host-centric(More)
As mobile phones advance in functionality and capability, they are being used for more than just communication. Increasingly, these devices are being employed as instruments for introspection into habits and situations of individuals and communities. Many of the applications enabled by this new use of mobile phones rely on contextual information. The focus(More)
PEIR, the Personal Environmental Impact Report, is a participatory sensing application that uses location data sampled from everyday mobile phones to calculate personalized estimates of environmental impact and exposure. It is an example of an important class of emerging mobile systems that combine the distributed processing capacity of the web with the(More)
Mobiscopes extend the traditional sensor network model, introducing challenges in data management and integrity, privacy, and network system design. Researchers need an architecture and general methodology for designing future mobiscopes. A mobiscope is a federation of distributed mobile sensors into a taskable sensing system that achieves high-density(More)
Imagers are an increasingly significant source of sensory observations about human activity and the urban environment. ImageScape is a software tool for processing, clustering, and browsing large sets of images. Implemented as a set of web services with an Adobe Flash-based user interface, it supports clustering by both image features and context tags, as(More)
The increasing ubiquity of the mobile phone is creating many opportunities for personal context sensing, and will result in massive databases of individuals' sensitive information incorporating locations, movements, images, text annotations, and even health data. In existing system architectures, users upload their raw (unprocessed or filtered) data streams(More)
The experimental future Internet architecture, Named Data Networking (NDN) [1], offers significant promise for content distribution applications. NDN treats data, instead of hosts, as the first-class entity on the network. Instead of addressing nodes on the network with IP addresses (numbers), NDN enables applications to name data (often in a human-readable(More)
Recently, building automation and management systems, BASs and BMSs, have shifted from using proprietary protocols and specialized hardware toward widespread adoption of IP-based open standard technologies. While the IP protocol suite improves software and hardware interoperability, practical large-scale BMS deployments face challenges, including the(More)
As mobile phones advance in functionality and capability, they are increasingly being used as instruments for personal monitoring. Applications are being developed that take advantage of the sensing capabilities of mobile phones many have accelerometers, location capabilities, imagers, and microphones to infer contextual information. We focus on one type of(More)
We envision the blossoming of sensing applications in an urban context, enabled by increasingly affordable and portable sensing hardware, and ubiquitous wireless access to communication infrastructure. In this paper, we describe the Partisans architecture, featuring infrastructure-supported selective data sharing and verification services. This effort(More)
