摘要：Vehicular Ad-hoc Network (VANET) becomes a fundamental subcategory of mobile ad-hoc networks which provides vehicles to communicate with each other and with roadside infrastructure in a smart way. Various VANET performance challenges are considered in terms of Quality of Service (QoS) due to vehicles speed and transmission rates. Different problems cause performance degradation as performance anomaly where high rates vehicles has to meet the speed of the low rates vehicle while transmitting data. In this paper a QoS-aware Signal to Noise Ratio (SNR) admission control mechanism (QASAC) is proposed to handle the performance anomaly problem while maintaining the QoS levels for different traffic types. QASAC has been compared against the latest SNR based admission control mechanism. QASAC has enhanced the performance of data delivery up to 23% in terms of data dropping rates for high priority traffic.
