Roofnet was an experimental 802.11b/g mesh network developed by the Computer Science and Artificial Intelligence Laboratory at the Massachusetts Institute of Technology (MIT).
Research included link-level measurements of 802.11, finding high-throughput routes in the face of lossy links, link adaptation, and developing new protocols which take advantage of radio’s unique properties (ExOR).
These public broadcasts measure the probability that a packet between two nodes in radio contact reaches its destination.
One media access and forwarding protocol tested with RoofNet was ExOR.
ExOR simulates some advantages of multicasted data networks by using conventional 802.11 digital radios operated in broadcast modes.
Each entry is the number of radio that is closest to the destination and has retransmitted that packet.
Roofnet's technology formed the basis for Meraki, a mesh networking startup founded by members of MIT's Parallel and Distributed Operating Systems group.
