An improved Markov Chain Model for Performance Analysis of IEEE 802.11 DCF
IEEE 802.11 MAC (Medium Access Control) protocol. The most important standard for wireless ad hoc network is a key topic for wireless network performance. Based on the strong points in the literature, and an accurate performance model for DCF (Distributed Coordination Function) is proposed by introducing the properties of retry limitation, busy medium and non-saturation issue. An extensive set of simulations and numerical calculations validate the model by showing high accurate results. During the last few years, wireless ad hoc networking has attracted many research interests due to a wide availability of wireless services and devices.
