[ns] Wimax mesh network Simulation using NS2

[Sandip Chakraborty]

Hii members,
                      I am currently doing a project on "Mesh tree construction for IEEE 802.11" using NS2. There is a patch available for simulating mesh network over NS2 from the following link:
http://info.iet.unipi.it/~cng/ns2mesh80216/
but I've not found any documentation on it. From where can I get a documentation of this wimax patch for NS2.
One more question is that, can anyone provide me some links or papers on current activities or research/project done on WiMAX mesh network....
Thanks and Regards,
Sandip
