The contribution of the authors' work to IEEE 802.11p vehicular ad-hoc network (VANET) analysis is as follows. They introduce a new analytical method to evaluate the performance of beaconing in VANETs. Their method is different from an approach in the literature, where 3- dimensional Markov chain with a huge large state space is proposed. The chain from this approach is practically inapplicable when the number of stations in the system is large. The proposed method is simple, precise and accounts for the features of vehicle-to-vehicle communications assuming at most one beacon at a time in the Medium access control (MAC)-layer buffer. The rest of the paper is organized as follows. In Section II the authors summarize the principles of broadcasting in IEEE 802.11. Section III is the core of this paper, where the assumptions of the authors' model and the proposed analytical approach are introduced. Some numerical results and discussion are presented in Section IV.
