• Link-level Measurements from an 802.11b Mesh Network (146)
  This paper analyzes the causes of packet loss in a 38-node
  urban multi-hop 802.11b network. The patterns and causes
  of loss are important in the design of routing and errorcorrection
  protocols, as well as in network planning.
• MIT Roofnet Implementation (183)
  This document describes the implementation of the MIT Roofnet, an experimental multi-hop 802.11b mesh network. Roofnet consists of about 50 nodes in apartments in Cambridge, MA. Each node is in radio range of a subset of the other nodes, and can communicate with the rest of the nodes via multi-hop forwarding. A few of the nodes act as gateways to the wired Internet.
