In this paper a novel analytical model for the saturation throughput of unslotted Carrier Sensing Multiple Access with Collision Avoidance (CSMA/CA) in wireless networks is proposed. A fixed point procedure is developed based on the interaction of the Physical layer (PHY) and the Medium Access Control sublayer (MAC). The output of the Clear Channel(More)

1 Research Assistant of the Fund of Scientific Research – Flanders (FWO-Vlaanderen) 2 ESAT-Telemic participates in the OPNET University Program for research [7, 8, 9] and educational projects [10, 11, 12]. Abstract OPNET contains a vast amount of node models that represent specific types of networking gear available in the marketplace. These models closely(More)
TCP-friendly rate control(TFRC) is an equation-based congestion control mechanism that competes fairly with TCP but has a much lower throughput variation, which makes it a better choice for streaming over the Internet. It is known that in a mobile network environment, after a handover TFRC can overshoot or under utilize the new link if the conditions there(More)
1 Research Assistant of the Fund of Scientific Research – Flanders (FWO-Vlaanderen) Abstract This paper describes the work performed in the framework of a Master’s thesis. The aim of the thesis was to make a simulation model in OPNET Modeler of the backbone at the K.U.Leuven, Belgium. The backbone consists of five Cisco Catalyst 5500 switches in a ring(More)
1 Research Assistant of the Fund of Scientific Research Flanders (FWO-Vlaanderen) Abstract In this paper we discuss how OPNET can be applied in advanced networking education, enhancing the practical skills of future network engineers. At the K.U.Leuven Master students in Electrical Engineering focusing on Telecommunications have to complete a complex(More)
To provide students with a practical knowledge of networking, the K.U.Leuven organizes design projects, complementary to the theoretical courses. Master students in Electrical Engineering (Telecommunications option) design a network for a specific service in a specific environment. During the academic year 2000-2001, students worked on one of the following(More)
1 Research Assistant of the Fund of Scientific Research Flanders (FWO-Vlaanderen) 2 ESAT-Telemic participates in the OPNET University Program for research and educational projects. Abstract It has become clear that the traditional Poisson model of data network traffic is insufficient for dimensioning and analyzing the performance of real-life networks.(More)
This paper introduces a novel hybrid packet-event / fluid-flow network simulation scheme. A packet-event simulation technique uses the arrivals and the departures of packets to model the queuing system. The applications that need fine-grained performance details, are simulated with an adapted event based approach. The impact of the background traffic on(More)
