IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS‚ VOL. 18‚ NO. 3‚ MARCH 2000 535 Performance Analysis of the IEEE 802.11 Distributed Coordination Function Giuseppe Bianchi Abstract—Recently‚ the IEEE has standardized the 802.11 protocol for Wireless Local Area Networks. The primary medium access control (MAC) technique of 802.11 is called distributed coordination function (DCF). DCF is a carrier sense multiple access with collision avoidance (CSMA/CA) scheme with binary slotted exponential

Control Theoretic Based Network Configuration Abstract: The optimal configuration of the contention parameters of a WLAN depends on the network conditions in terms of number of stations and the traffic they generate. Following this observation‚ a considerable effort in the literature has been devoted to the design of distributed algorithms that optimally configure the WLAN parameters based on current conditions. In this paper‚ we propose a novel algorithm that‚ in contrast to previous proposals

A Derivation of an Upper Bound for the Number of Configurations of an n×n×n×n Rubik ’s Cube By David Smith 1. Introduction C4(n) is a formula for an upper bound of the number of distinguishable configurations of an n×n×n×n Rubik ’s Cube‚ which will be derived in this paper. It will be assumed that the reader is familiar with a 4-dimensional Rubik ’s Cube. Online‚ one can find the free computer program Magic Cube 4D‚ developed by Melinda Green‚ Don Hatch‚ and Jay Berkenbilt‚ which is a completely
