Abstract	In this paper we propose resource allocation schemes for TDMA/TDD based high performance link adaptable wireless LANs and examine their interrelation with user buffer. User rates are dynamically adjusted based on their distance from the access points and changes as user moves. We simulate three resource allocation policies namely Minimum Overhead Round Robin (MORR), which does not depend on userpsilas buffer condition, Weighted Minimum Overhead Round Robin (WMORR) which is a function of user buffer as well as the waiting time for transmission opportunity and Weighted Round Robin (WRR) which is a function of user buffer only. We evaluate average buffer packet drop probability due to buffer overflow and average frame overhead in uplink phase of the TDMA/TDD frame. Our results show that the second adaptive resource allocation technique i.e. WMORR outperforms the other two.
