In recent decades, vehicular ad hoc networks (VANETs) have emerged the big way mainly to perform high quality and intelligent communication. The mode of transmission includes the vehicles and the roadside units and due to high speed in rapidly changing mobility several link failures and delay occurs in the network. Several earlier models are developed to improve the mobility characteristics of the dynamic vehicles but still this topic is under an open research area. Mainly to expand the efficiency and confidentiality of the devices in this article trust based relay node selection and efficient multi hop clustering model (TRSEMC) is developed. The core modules of this model are efficient network construction, multi hop clustering and vertical trust management. Even through this process the efficiency is greatly increased and that leads to expanding the life span of the devices. The proposed concept is constructed in the simulator called NS3 and the matrix which are taken to analyses the performance of the network are throughput, network delay, routing overhead, transmission accuracy and energy efficiency. This TRSEMC greatly fulfills the identified research gap and through an effective clustering mechanism the efficiency of the vehicles is increased than the earlier models.
