       Scheduling  is  an  essential mechanism in IEEE 802.16 networks
       for  distributing  the  available  bandwidth  among  the active
       connections  so  that their quality of service requirements can
       be  furnished. Scheduling mechanisms adopted in wired networks,
       when  used  in wireless networks lead to inefficient use of the
       bandwidth   since  the  location  dependent  and  time  varying 
       characteristics of the wireless link usually are ignored by the
       wired  networks.  This  paper  introduces  a standard-compliant
       cross-layer scheduling mechanism which considers the modulation
       and  coding  scheme  of  each  mobile  station  to increase the
       efficiency  of  channel  utilization  while  furnishing the QoS
       requirements of the connections.
