Abstract :
IEEE 802.11 wireless local area networks (WEAN) widely deployed in recent years work mostly with distributed coordinated function (DCF) at medium access control (MAC) layer without QoS (quality of service) support. This paper aims at modelling WLAN network for a semi-dynamic simulator: Bianchi´s DCF model is extended to include asymmetric TCP traffic for mobile stations with different radio conditions and modulations; radio resource management (RRM) algorithms are devised to guarantee QoS; adaptation of the model for a semi-dynamic simulator is described. Simulation results illustrate the effectiveness of the proposed modelling
