— This paper proposes an admission control algorithm that enables the upcoming IEEE 802.11e contention based Enhanced Distributed Channel Access (EDCA) to provide quantitative bandwidth guarantees for Wireless Local Area Networks (WLANs), rather than a relative prioritized service. The algorithm estimates the throughput that flows would achieve if a new(More)
The paper investigates fairness in a wireless LAN environment in which stations experience unequal signal qualities due to location and interference factors. This causes differences in transmission rate among mobile stations due to the use of link adaptation schemes. We analyse fairness in the presence of these impairments for the distributed contention(More)
As a token of my deep appreciation for their professionalism and dedication to the ideals of our magazine, I hereby acknowledge with the list below the many reviewers that have reviewed tirelessly papers for IEEE Network during the past year. Their behind the scenes work provides the strong foundation upon which the quality papers that you read in our(More)
In this paper we report on the impact of the random waypoint model on infrastructure wireless networks that use multi-rate schemes. The waypoint model causes a higher concentration of nodes near the centre of the mobility area. Consequently, we show that a wireless network could appear to achieve higher capacity, and that base stations near the centre of(More)
This paper describes an algorithm designed to estimate the future cell throughput of a multi-rate wireless network based on measurements. The achievable throughput of a cell depends on the transmission rate used by the mobile nodes. We propose to use a measurement window to gauge the aggregate channel usage by multiple nodes over a period of time instead of(More)
