    Implementacja punktu dostępu do sieci standardu IEEE 802.11 ze wsparciem jakości świadczonych usług
    (Wydawnictwa AGH, 2010/2011) Natkaniec, Marek; Kosek-Szott, Katarzyna; Pach, Andrzej R.; Staniszewski, Andrzej; Witosz, Mariusz
    The paper is related to the implementation of mechanisms for providing QoS in access point based on IEEE 802.11 standard. Three different methods for providing QoS are showed: for the data link layer (using IEEE 802.11 function), for the network layer (using queuing disciplines), and for the both mentioned layers (using hybrid solution). These mechanisms allow for improving and proper control of services provisioning in IEEE 802.11 wireless local area networks.

    PUMA-TCS - nowy protokół warstwy MAC ze wsparciem jakości świadczonych usług
    (Wydawnictwa AGH, 2010/2011) Natkaniec, Marek; Kosek-Szott, Katarzyna; Szott, Szymon
    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.
