    PUMA-TCS - nowy protokół warstwy MAC ze wsparciem jakości świadczonych usług

    There is a growing interest in QoS provisioning for wireless local area networks in recent years. Because of this, the IEEE 802.11e standard was introduced. Unfortunately, a few research papers show, that it has a number of serious flaws. The presented work describes a new protocol called PUMA-TCS (Priority Unavoidable Multiple Access with Traffic Category Support), that allows for better than IEEE 802.11e traffic differentiation and QoS guarantees. Research results and comparative analysis of protocols using selected simulators are also included in the paper. This allows to reveal a pros and cons of both channel access schemes.
