IEEE 802.11 MAC Protocol Performance Evaluation in Operational Environments

摘要

The IEEE 802.11 MAC protocol is widely used for wireless local area networks. Consequently, it is important to examine the protocol performance in operational environments. This thesis presents a simulation study of the performance of the IEEE 802.11 MAC protocol in multihop, jamming, and mobile node environments. The effects of the request-to-send mechanism and fragmentation in these environments are also studied. The average throughput and delay are obtained from the simulation and these results are then used to analyze the protocol performance.
