Abstract
This paper presents a new clustering mechanism for the multi-hop relay in vehicular communication. In the proposed mechanism, the cluster-head selection is implemented using the enhanced hybrid wireless mesh protocol (E-HWMP) protocol, which is based on the IEEE802.11p and IEEE802.11s standards. Then, multi-hop routing is designed for VANET in Wireless Mesh Networks (WMNs). Therefore, the main aim of this study is to enhance the integration of VANET with a cellular network (i.e., LTE). As a result, the coverage can be extended. The proposed E-HWMP mechanism is evaluated by the NS2 simulator, and the VanetMobiSim is used as a mobility generator. The proposed E-HWMP mechanism is compared to the existing mechanism based on the packet’s delivery ratio, packet loss, throughput, overhead, and average end-to-end delay. The results demonstrate that the proposed E-HWMP mechanism outperforms the existing clustering mechanism.

Summary
Vehicular ad hoc network (VANET) has attracted the attention of academia as well as industries due to its promising applications. VANET is categorized based on vehicles’ locations and their speeds and is classified into two major categories namely, Vehicle-toVehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication [1]. VANET is a dynamic network topology which consists of high-speed vehicles that moves in a specific direction. There are many services (e.g., driver aid, collision alarm, traffic information, and tracking) provided by VANET in order to improve road safety and transportation efficiency [2]. To meet the road-side safety, transportation communication efficiency, and the demands for the various entertainment applications for vehicles, the selection of the appropriate protocol is strongly recommended. Our paper addresses the above identified issues by the following key contributions: 1) Design a new clustering mechanism for the multihop relay in vehicular communication
