BATMAN Routing

Return to the Index

BATMAN is slightly worse than pre-existing algorithms for static architecture. It is however superior in practice since it handles endpoints that are continuously in motion.

• Mesh networking over semi-unreliable broadcast stations.
• A "vector" routing protocol; knows distance and strength to other nearby nodes.
• Piecemeal; there is no "central routing" database.

TODO Need to bother to read all the docs for this.

Concept

• Each node stores only direction and power to next best hop for a route.
• Nodes broadcast "hello" with their address, time to live and sequence numbers.
• Nodes propagate received "hellos" at most once.
• More frequent and higher quality "hellos" indicate that transmitter is the best route.
