Overview

• A network in the Arbor Lodge neighborhood of North Portland has been experimenting with various implementations of ad-hoc routing protocols.

  2 [http://pdos.csail.mit.edu/roofnet/doku.php roofnet] nodes are still in operation, but the rest of the network has since converted over to [http://olsr.org OLSR]

  AaronBaer, TomHiggins and JasonMcArthur are currently hosting nodes.BR

Nodes

• ["Node39542"] is the primary gateway.

  • Map: NodeId:39542

• ["Node39573"] sits out on a garage with a 7dBi omni attached.

  • Map: NodeId:39573

• ["Node134"] sits 3 hops back inside the network and it's clients rely on the upstream nodes for internet access.
• ["Node236"] sits somewhere inside the network.

Equipment

• The core network consists primarily of NetgearWgt634u nodes and a few Linksys WRT54G.
