QoS Enhancement using Intelligent Cluster Head Selection Routing Technique in Vehicular Ad Hoc Networks in case of RSU failure

Use of clustering in VANET have proven effective technique to enhance QoS. Clustering based solution in current research designed by considering the geographical distances as well as network dynamics (mobility). Present research work has improved the QoS, yet the failure of infrastructure is not considered, which will definitely hamper the QoS where the quality of infrastructure is not good. This paper, intelligent cluster head routing protocol (ICHR) is proposed to work with RSU failure conditions in network efficiently for VANET. Additionally, the method of selecting cluster head has been changed to improve the QoS significantly. In case of RSU failure, the Intelligent CH (ICH) is selected from the all CH nodes based on the maximum probability of all three parameters to transmit the data over the alternate neighboring RSU through LTE network which is already in use for providing internet connection.
