CarNet: A Scalable Wireless Network Infrastructure


Progress Report: July 1, 2000–December 31, 2000

Project Overview


Smart devices will require self-configuring wireless data networks that support mobility. Current network technologies are awkward for smart devices: for example, the Internet does not support mobility, the cellular telephone network requires expensive pre-deployed infrastructure, and existing "ad-hoc" networking proposals do not scale well. The CarNet project will design and build a network system that avoids these limitations by use of geographic reasoning.

The scope of the CarNet project includes:



Progress Through December 2000

In the first six months of the project we accomplished the following goals:



Research Plan for the Next Six Months

Our main task for the coming months will be to continue deploying a test network. We hope to have a network of many dozens of nodes in production use. Most of the nodes will be Compaq iPaq hand-held PDAs running Linux. We hope to port enough useful software, such as a Web browser, group calendar, mapping software, that people in our lab will find them useful and use them a lot. This use will allow us to accumulate measurements of typical usage patterns, particularly motion and communication patterns. The measurements will in turn help us design and predict the behavior of future networks.
