Mesh is packet radio with constantly updated IP routing between hosts. TCP takes care of the end to end. Bandwidth isn’t a big concern. A reliable, ubiquitous wireless network is the aim. Run with 802.11b for lowest common denominator interoperability at 2.4 GHz. Cross city backbones on 5 GHz. The Freifunk network in Germany has been very successful. I think they opted for AODV instead of OLSR to reduce over the air traffic. OLSR is preferred when low latency is critical and using bandwidth to keep routing tables fresh is not an issue. It doesn’t scale well to very large networks.
