A new analytical model of enhanced distributed channel access (EDCA) which builds on an existing comprehensive model is presented. The model implements virtual collisions and combines the advantages of both accurate backoff countdown and accurate arbitration inter-frame space (AIFS) differentiation. The correctness of the model is evaluated by comparison with ns-2 simulations and two previous models. The comparison gives very good results.
