Efficient block size based polling scheme for IEEE 802.11e wireless LANs

In the recent draft of the 802.11e MAC (2004), the hybrid coordinator (HC) gives transmission opportunity (TXOP) for a station to transmit burst frames for improving throughput efficiency. To use this block ack mechanism efficiently, the relationship of throughput and relative parameters is analyzed, and the throughput efficient condition is evaluated [Il-Gu Lee et al., 2004]. In this paper, we proposed an efficient block size based polling scheme using an adaptive algorithm to improve the aggregate throughput and to reduce the polling overheads without degrading throughput and delay.
