In this paper, we propose an alternative QoS architecture for the IEEE 802.16 Standard, that incorporates a priority based packet scheduling and a new traffic shaping. For this, we present the ideas of a traffic conditioner based on concept of "Fair Marker".
—In this paper we consider a peer-to-peer grid system which provides multiple services to its users. An incentive mechanism promotes collaboration among peers. It has been shown that the use of a reciprocation-based incentive mechanism in such a system prevents free-riding and, at the same time, promotes the clustering of peers that have mutually profitable… (More)
— Broadband Wireless Access (BWA) systems offer a solution for broadband access and high data rate transmission of multimedia services with distinct Quality-of-Service (QoS) requirements through a wireless medium. IEEE 802.16 Standard specifies the PHY and MAC layers for BWA systems. However, in spite of including the possibility for QoS support, the… (More)
There are many who have helped make this dissertation a reality. Thanks to My research committee: Andrew Hanson, whose editing made the content of this document more understandable, Dennis Gannon, who found funding for me when funding was scarce, Bernard Flury, who taught me probability and statistics, Rob Shakespeare, who gave me both support and a user's… (More)
— The Broadband Wireless Access (BWA) technology has been proposed to support different traffic classes with distinct quality of service (QoS) requirements in broadband metropolitan area networks. Therefore, as part of its specifications, such a system must properly address the combined requirements of wireless communications and multimedia applications. We… (More)
shu Liu. Finally, thanks to my wife, my son, and my families in Taiwan. To my wife, Minru Wang, who took care of everything; to my son, Eugene Wang, who gave me enumerous fun to help me continuing my work; to my families for their endless support.
Abstract: Co-design methodologies have arisen for supporting the development of digital systems composed of mixed hardware/software. Partitioning is performed by co-design tools for splitting the functionality of the original system among components. In this paper, a partitioning approach based on a Petri net intermediate format is proposed. The new model… (More)
