An Analysis of Star Topology IEEE 802.11e Networks in the Presence of Hidden Nodes

This article presents a novel simulation study of IEEE 802.11e based environments. The most important innovation of this article lays in demonstrating a thorough analysis of two star topology networks, which shows how seriously they can be degraded by the presence of hidden nodes. The main stress is put on the limitation of the ability to provide services with the requested QoS. The usefulness of the RTS/CTS mechanism is also discussed. According to the authors' best knowledge, similar studies have never been made.
