A new effective interference-based capacity model was proposed for vehicular ad hoc network safety message broadcast scenario in M. Niet al.(Commun. Lett., vol. 19, no. 4, pp. 621–624, Apr. 2015). This letter is a reconsideration and extension of the model in Niet al.. First, we point out that the analysis in Niet al.is incomplete and show a new derivation of the node transmission probability and the SIR distribution accounting for the impact of asynchronous timing of hidden terminals and all possible interference occurrence cases. Second, the analysis is extended to the derivation of other important quality of service metrics, such as packet reception probability, packet reception ratio, and transmission capacity. The proposed analysis is cross validated by MATLAB, PYTHON, and NS2 simulations.
