Internet access protocol providing QoS in vehicular networks with infrastructure support

Controlled vehicular Internet access protocol with QoS (CVIA-QoS) is a cross-layer solution for vehicular multihop networks spanning MAC and routing functions with infrastructure support. CVIA-QoS employs fixed gateways along the road which perform periodic admission control and scheduling decisions for the packet traffic in their service area. The CVIA-QoS protocol is based on CVIA protocol that was designed only for the best-effort traffic. The most important contribution of the CVIA-QoS protocol is providing delay bounded throughput guarantees for soft real-time traffic which is an important challenge especially for a mobile multihop network. After the demands of the soft real-time traffic is met, CVIA-QoS supports the best-effort traffic by allocating the remaining bandwidth
