Throughput performance of non-persistent CSMA/CD quasi-diffuse infrared local area networks under an imperfect average power sensing collision detection method

摘要

The authors consider two cellular indoor quasi-diffuse infrared carrier sense multiple access with collision detection (CSMA/CD) wireless local area network (WLAN) architectures, one including satellite-based cells and the other passive-reflection-based cells. They study the impact of imperfect collision detection on their performance. Analytical models are developed to calculate the throughput performance under an average power sensing collision detection method. It is found that a satellite-based multicell network performs significantly better than a passive-reflection-based one and that the average power sensing collision detection method gives little improvement over CSMA for moderate to high cell ranges.
