| Abstract: | This paper researches the MAC and part of PHY layer's characteristic of the newly-issued protocol IEEE802.16.Based on it,the paper simulates theBWA system in TDMA-DAMA/FDD mode by using computer.In this model,an uplink bandwidth-scheduling algorithm is devised to implement the dynamic bandwidth allocation(DBA).The result shows the performance of the DBA and its impact to MAC queue length and network delay under the environmet with CBR and VBR terminals. |
