Abstract:
Modeling and performance analysis of the media access control layer are extremely significant. Therefore, the performance evaluation helps a researcher in discovering the inherent cause of many problems, and may even suggest possible solutions. This is why much of the research work aimed to achieve an accurate evaluation. However, a lot of work does not consider the main difference between the busy probability and the collision probability in analytical mathematical models. Some of them consider both probabilities to be the same or ignore the busy probability and consider only the collision probability, which is not accurate. This paper proposes a new performance evaluation by creating a new mathematical model to compute a packet transmission probability for IEEE 802.11 DCF. Therefore, we enhance Bianchiâ€™s model by adding a new state to represent the busy probability in the mathematical model, which helps to achieve the highest accuracy performance evaluation of IEEE 802.11 DCF.
