Research and design of network card driver based on IEEE802.11p standard
Abstract With the development of transportation, and the increasment of car occupancy, much higher demands of transport management have been asked for. Therefore, the vehicle networking researches have aroused much attention. Vehicle Ad-hoc Network (VANET) provides wireless access in a high-speed mobile environment, and builds a wireless communication between the vehicle and the vehicle, the vehicle and the roadside infrastructure. VANET can solve the traffic congestion problem, ensure traffic safety and traffic efficiency, and provide the vehicle driver assistance applications and in-car entertainment.
This paper mainly discusses the implementation of network card driver based on IEEE802.11p standard. 802.11p, also known as WAVE, is a standard protocol intended for future traffic systems in order to support safety and commercial non-safety applications for vehicular communication. This paper adopts 802.11p network card DCMA86P2, Atheros5414B chipset to implement wireless network driver in high speed mobile environment. To be specific, this paper presents the method of implementing IEEE 802.11p standard based on 802.11a driver, compat-wireless source code ath5k; and establishes Ad-Hoc network communication testing.
Key words: 802.11p; 802.11a; ath5k; VANET
