Abstract :
This paper addresses the problem of MAC performance evaluation of a contemporary IEEE 802.11 WLAN. The network is observed under saturation conditions and the packet transmission probability analysis is conducted with the novel regenerative approach. The proposed model accounts for collision resolution protocol parameters, packet retry limit, coexistence of unicast and broadcast traffic, and heterogeneous QoS environment. Our analytical model is a generalization of several well-known models extensively used in the field. The obtained results are verified to demonstrate perfect agreement with ns-2 simulations.
