A Gain-Computation Enhancements Resource Allocation for Heterogeneous Service Flows in IEEE 802.16 m Mobile Networks

Algorithm 2

An adaptive resource allocation scheme.
BEGIN
(i) Initialization
Equal power is allocated to groups
; ;
; ; .
(ii) Users Ordering
for to do
 Sort in decreasing order.
 Order user according to its best channel gain .
end for
(iii) Subchannels Allocation
for to where do
find the subchannel n where the user k has its best
channel gain.
Step (1):
if then

Sub-step :
if then
   {% the subchannel n is not allocated}
{% allocate the subchannel n}
