  1. MapReduce is a programming model and an associated implementation for processing and generating large data sets. Users specify a map function that processes a key/value pair to generate a set of intermediate key/value pairs, and a reduce function…

  3. Information and communication technology (ICT) consumes energy, but is also an important means of conserving energy. Conventionally, it has done so by optimizing the performance of energy-using systems and processes in industry and commerce. In the…
  4. 6LoWPAN is a protocol definition to enable IPv6 packets to be carried on top of low power wireless networks, specifically IEEE 802.15.4. The concept was born from the idea that the Internet Protocol could and should be applied to even the smallest…
  5. The Internet of Things is the next big possibility and challenge for the Internet. Extending the web architecture to this new domain of constrained wireless networks and devices will be key to achieving the flexibility and scalability needed to make…
  6. An emerging area in ubiquitous computing is networked sensor systems. The typical approach is to connect sensor-actuator devices using classic network infrastructures at a low level. These networks can serve as infrastructures to dynamically…
  7. The role of computers in the modern office has divided our activities between virtual interactions in the realm of the computer and physical interactions with real objects within the traditional office infrastructure. This paper extends previous…
  8. The Web 2.0 wave brings, among other aspects, the Programmable Web:increasing numbers of Web sites provide machine-oriented APIs and Web services. However, most APIs are only described with text in HTML documents. The lack of machine-readable API…
  9. This paper describes methods for service selection and service access for mobile, sensor-enhanced web clients such as wireless cameras or wireless PDAs with sensor devices attached. The clients announce their data-creating capabilities in "Produce"…
  10. The Internet may be the most complex system ever engineered; from the first host in 1969, it's grown to comprise more than 1 billion routable host addresses (Meng et al., 2005). Its future expansion may be more dramatic still due to the demand to…
  11. This paper demonstrates the use of a physical/spatial computing model (SPREAD) to build contextual web (or wap) information systems. The approach presented consists in spreading information items in the environment (through short distance wireless…
  12. Although mobile services can be used ubiquitously, their employment and the interaction with them are still restricted by the constraints of mobile devices. In order to facilitate and leverage mobile interaction with services, we present a generic…
  13. As more and more physical information becomes available, a critical problem is enabling the simple and efficient exchange of this data. We present our design for a simple RESTful web service called the Simple Measuring and Actuation Profile (sMAP)…
  14. Automatic identification represents a set of technologies that seems to work like magic. It's knowing instantly what's in a crate from 30 feet away; talking or looking into a machine that will automatically unlock a door; laser zapping a simple…
