A Survey of IEEE 802.11p MAC Protocol
Source: Cyber Journals
The 802.11p standard has attracted much attention as part of the WAVE protocol in VANETs. The 802.11p MAC protocol is very challenging owing to the characteristics of VANETs. In this paper, a survey of the IEEE 802.11p MAC protocol in vehicular environments is presented. Firstly, the existing evaluations of 802.11p are presented and classified, and subsequently, the enhancements which have been proposed for 802.11p MAC, are presented and discussed. Based on the above-mentioned evaluations and enhancements, a conclusion is reached regarding the present situation of this protocol.
