A Framework for Providing Optimal QoS Routing Information in Vehicular Ad Hoc Network

The unique characteristics of VANETs make numerous conventional ad hoc routing protocols unsuitable. One of the most challenging tasks in VANET is Quality of Service (QoS) which is determined by numerous parameters such as packet delivery ratio, end-to-end delay and connection duration. This paper introduces geographical QoS routing information capable of providing optimal paths between the source and all destinations that fulfill certain QoS requirements for packet forwarding. This is an efficient solution for communications and information delivery in VANET. Cluster-based method is to be employed to enhance the performance protocol as it incurs lower overhead throughout topology updates and has faster re-convergence.
