Research output: Contribution to journalArticlepeer-review


This study presents an unsaturated two-dimensional (2D) Markov model to analyse the packet collision probability and the throughput performances of the stations (STAs) in a distributed coordination function network. Compared with the previous 2D models, it takes the flexible buffer size of the STA into consideration. Compared with the 3D models, it has the advantage of low complexity by avoiding matrix operations. From the numerical results, the authors explain the approximations used in the analytical models proposed in the common existing literatures, and discuss their effect on the model accuracy.
