Mesh Networking
A working mesh network (Ad Hoc mode with self-propogating routes) was set up with all the desktops and Access Points of the different groups.
Ad Hoc Mode
Historically Ad Hoc mode was not used much by consumers, and therefore not well supported by the manufacturers' firmware. This has started to change recently, both from the commercial side and with the proliferation of Linux-based firmware.
Operation
Rob set up a metrix box to start the mesh network with the ISSID "ictp-mesh".
On Ubuntu Linux desktops OLSR was installed (the Open Link State Routing Daemon). A configuration file was provided and discussed.
Freifunk firmware was flashed to the Linksys WRT 54 GL Access Points and they were configured to also join the mesh.
Security Considerations
Although DOS attacks will easily be traced and OLSR will test routes continually, Mesh Networking is still wide open to interference and attack.
A suggested solution is the development of a GNUPG plugin so that each access point has a key-pair, joins a trust model, and signs it's routes when propogating changes.
