Abstract :
Wireless networks come in force into the market of computer communications. Unfortunately, several standards coexist (e.g., IEEE 802.11, Bluetooth, HomeRF, HIPERLAN), leading to various types of products. The purpose of this article is to present an overview of those standards and to establish a comparative evaluation. We mainly focus on the medium access control protocols and their ability to support the quality of service required by multimedia applications. Those protocols generally support two modes of operation, a random access mode for asynchronous traffic and a polling mode for real-time synchronous traffic. This article analyzes each protocol´s ability to support user QoS requirements.
