摘要:IEEE 802.11p vehicular ad hoc network (VANET) applies multiple channels, including one control channel (CCH) and six service channels (SCHs); the enhanced distributor channel access (EDCA) mechanism is used to support wireless channel assignment and QoS requirements. But the method of SCH assignment is not proposed in IEEE 802.11p standard. We present a scheme to perform SCH assigning, previous transmission indicators of service channels are detected dynamically by service channel assignment controller set in medium access control (MAC) layer, service packets would be delivered into suitable SCH and EDCA access category (AC) queue according to SCH reservation probability and estimated transmission delay. Saturated throughput of our scheme in SCH is analyzed by theoretical model in different conditions; the results show that it can ensure higher SCH utilization and is an efficient way to improve performance of intelligent transportation system. © 2014 Springer International Publishing Switzerland.
