Interesting applet of a multi-hop ad-hoc network by Nelson Minar (ex-MIT ML) who now works at Goooogle. In the above screen shot, Minar explains: “Nodes in the network are drawn as squares. Green lines between nodes indicate physical links; each node has a limited transceiver range, faintly visible as grey circles surrounding the yellow nodes. In our simulation these nodes are moving, so the physical links are constantly breaking and reforming as nodes move in and out of range with each other.” This approach is similar to how Umbrella.net will function once the system architecture is in place. In the mean time, it’s nice to see a simulation of how the packets are dynamically routed between nodes and hop from node to node.
