An Improved Analytical Model for IEEE 802.11 Distributed Coordination Function under Finite Load

By Debasish DATTA, Saswat CHAKRABARTI and Rama Krishna CHALLA

Abstract

In this paper, an improved analytical model for IEEE 802.11 distributed coordination function (DCF) under finite load is proposed by closely following the specifications given in IEEE 802.11 standard. The model is investigated in terms of channel throughput under perfect and slow Rayleigh fading channels. It is shown that the proposed model gives better insight into the operation of DCF
