Abstract
IEEE 802.11x is the new standard for communication in a wireless LAN. Despite these differences, 802.11 is required to appear to higher layers (LLC) as a traditional 802 LAN. When assessing the performance of a wireless LAN, it is especially important to consider how this LAN will be used. When analyzing wireless networks, there arises a need to evaluate the whole network or a part of it. Whole Vehicular network, discussed in this work, consist of three layer networks. When analyzing wireless networks, the theory of queues net is used. During the research involving analytical methods, wireless network performance characteristics of various types were assessed. In the result of the experiment, the mathematical models for three layer wireless networks were selected as ones who are to be used for choosing an optimal method for performance evaluation of Short range communication Vehicular network. .

Highlights
In due time vehicular wireless network is made using the IEEE 802.11p standard. This standard enables a wireless access to vehicular environment. 802.11p functions in the 5.9 GHz range; this technology permits access to navigational options, multimedia information and telemetry
For creation of a wireless network that would work by 802.11p standard, more expensive equipment is required than for other IEEE wireless network standards
This is the configuration that will provide the maximum throughput for 802.11g devices because, as described above, there are no throughput degradations caused by long slot times, 802.11b devices, or protection mechanisms[4]
