[ns] MIH module for WIMAX in NS2.29

[El hadi Cherkaoui]

Dear all,

I have a question about the implementation of SEND_LINK_UP , 
SEND_LINK_GOING_DOWN, SEND_LINK_DOWN, SEND_LINK_DETECTED in the vertical 
handover between WIFI , UMTS and  WIMAX.

Why SEND_LINK_DETECTED  , SEND_LINK_UP , SEND_LINK_DOWN are taken into 
consideration only by sssheduler.cc and bssheduler.cc and SEND_LINK_GOING_DOWN 
by mac802.16.cc ??

thank you.
