  • 摘要:AbstractQuality of service (QoS) guarantees in vehicular ad hoc networks (Vanets) is much more challenging due to the high mobility of its mobile hosts, multi-hop communications and contention for channel access. With the increasing demand for wireless communication technologies development of real-time and multimedia applications, there is a need to provide QoS guarantees, which results in a low number of admitted real-time and multimedia flows. Most of the current routing protocols for QoS ad hoc select only path guaranteeing bandwidth and do not deem throughput optimization. Typically, the QoS is measured in terms of throughput, packet loss as well as average delay for a liable bandwidth. In this paper, UDP Transport layer protocol is used as the real-time application to satisfy bandwidth requirement while optimizing network throughput and packet drop to provide QoS for nodes running the IEEE802.11 MAC. However, one of the DSRC's seven-channel bandplan is used as the Data channel defined in the appropriate functions of the seven channels spanning 10MHz bandwidth each. The results obtained through NCTUns simulator are used for analysis of throughput for UDP real-time traffic application.
