In this article, the evaluation of a 2-layer network has been performed. Buzen’s method has been applied for the 2-layer closed network performance calculation. This paper offers a 2-layer model of a wireless vehicular network and presents a bandwidth calculation of each network node. There is also described how the vehicle movement speed and the number of terminals connected to fringe stations influence the bandwidth of a 2-layer wireless vehicular network. Bandwidth calculations of IEEE 802.11g and IEEE 802.16 are demonstrated. The mathematical models for 2-layer wireless networks have been selected as ones which are to be used for choosing an optimal method for performance evaluation of a short range communication vehicular network.
