MASS 2007, 4th IEEE International Conference on Mobile Ad-hoc and Sensor Systems, October 8-11, Pisa, Italy
In this paper, we propose a new QoS architecture
for PMP 802.16 systems operating in TDD mode over
WirelessMAN-OFDM physical layer. It includes a call admission
control policy and a hierarchical scheduling algorithm.
The CAC policy we propose adopts a Min-Max fairness
approach making efficient and fair use of available resources.
The proposed scheduling algorithm flexibly adjusts
uplink and downlink bandwidth to serve unbalanced traffic
while considering adaptive modulation and coding (AMC)
scheme. The efficiency of the proposed QoS architecture is
revealed through simulation.
