Executive Summary

Gamal et al. (IEEE Trans. Inform. Theory 52:2568 - 2592, 2006) showed that the end-to-end delay is n times the end-to-end throughput under centralized time division multiple access scheduling. In the authors' other paper, it was proved that the relationship between the end-to-end throughput and the end-to-end delay of Gamal et al. still holds under the IEEE 802.11 Distributed Coordination Function (DCF) when the carrier sensing range and the packet generation rate are jointly optimized. The main purpose of this paper is to determine whether the result in their other work is achievable when the transmission range is adjusted instead of the carrier sensing range.
