【已经解决】关于WAVE和IEEE802.11p，谢谢
现在在看关于VANET的内容，看到论文中说IEEE802.11p是它的PHY和MAC标准，但从IEEE的标准库中却没搜到该标准，相关的是WAVE的四个已批准的标准：1609.1，1609.2，1609.3，1609.4。
想请教下各位大虾，WAVE和IEEE802.11p 的关系是什么呢？感觉WAVE好像是MAC层以上的标准
ps：如果哪位大虾有802.11p能否传我一份，感激涕零！！！

802.11p是802.11wlan系列标准之一，定义的是车载接入方面的PHY和MAC层的标准
当前该标准还处于草案阶段，没有正式公布。
至于其和WAVE的关系，可以看看这个
WAVE is a mode of operation for use by IEEE Std 802.11™ devices in environments where the physical
layer properties are rapidly changing and where very short-duration communications exchanges are
required. The purpose of this standard is to provide the minimum set of specifications required to ensure
interoperability between wireless devices attempting to communicate in potentially rapidly changing communications
environments and in situations where transactions must be completed in time frames much
shorter than the minimum possible with infrastructure or ad hoc IEEE 802.11 networks. In particular, time
frames that are shorter than the amount of time required to perform standard authentication and association
to join a BSS are accommodated in this amendment.
This specification accomplishes the following:
• Describes the functions and services required by WAVE-conformant stations to operate in a
rapidly varying environment and exchange messages either without having to join a BSS or
within a WAVE BSS.
• Defines the WAVE signaling technique and interface functions that are controlled by the IEEE
802.11 MAC
This amendment to IEEE Std 802.11™ is based on extensive testing and analyses of wireless communications
in a mobile environment. The results of these efforts were documented in ASTM E 2213-03, "Standard
Specification for Telecommunications and Information Exchange Between Roadside and Vehicle
Systems - 5.9 GHz Band Wireless Access in Vehicular Environments (WAVE) / Dedicated Short Range Communications
(DSRC) Medium Access Control (MAC) and Physical Layer (PHY) Specifications". This document
is available from: ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken,
PA, 19428. This amendment to IEEE 802.11 is based on the ASTM E 2213-03 document.
Please see document, 11-07-2045-00-000p-Development of DSRC/WAVE Standards, (latest version) for
additional information on the development of the amendment for WAVE.
