###### Abstract  
Vehicles are highly mobile nodes; therefore, they frequently change their topology. To maintain a stable connection with the server in high-speed vehicular networks, the handover process is restarted again to satisfy the content requests. To satisfy the requested content, a vehicular-content-centric network (VCCN) is proposed. The proposed scheme adopts in-network caching instead of destination-based routing to satisfy the requests. In this regard, various routing protocols have been proposed to increase the communication efficiency of VCCN. Despite disruptive communication links due to head vehicle mobility, the vehicles create a broadcasting storm that increases communication delay and packet drop fraction. To address the issues mentioned above in the VCCN, we proposed a multihead nomination clustering scheme. It extends the hello packet header to get the vehicle information from the cluster vehicles. The novel cluster information table (CIT) has been proposed to maintain several nominated head vehicles of a cluster on roadside units (RSUs). In disruptive communication links due to the head vehicle's mobility, the RSU nominates the new head vehicle using CIT entries, resulting in the elimination of the broadcasting storm effect on disruptive communication links. Finally, the proposed scheme increases the successful communication rate, decreases the communication delay, and ensures a high cache success ratio on an increasing number of vehicles. v 2021 14 September 2021 15 September 2021 15 September 2021 15 September 2021 15 July 2021 14 September 2021 15 September 2021 15 September 2021 15 September 2021 15 September 2021 15 July 2021 14 September 2021 15 September 2021 15 September 2021 15 September 2021 15 July 2021 15 July 2021 15 July 2021 15  
However, these vehicles also communicate with infrastructure for a quick response [7; 8]. In vehicle-to-infrastructure (V2I) communication, vehicles forward information to road side units (RSUs). When an RSU receives the message from the vehicle, it adds the required information. However, an RSU is an uncompromised entity in V2I communication [9]. Therefore, an RSU sends a quick response to vehicles, provides efficient data delivery, ensures efficient caching, and provides reliable communication. However, if the vehicle changes its location, then the handover process with the new RSU starts again, which increases the network load and packet drop ratio. To solve the above-mentioned problem, an information-centric network (ICN) is proposed. It is a content-based communication network instead of IP-based communication. When the requester vehicle propagates the request packet, each intermediate vehicle receives the request, uses the prefix match, and searches the requested content in the local cache of the vehicle. If the content is not found, then it updates entries in the table and forwards them to other vehicles in its vicinity till it is found the provider vehicle [4; 5]. The producer vehicle sends the response in a response packet and uses the reserve path of the request packet. However, the content-centric network (CCN) is a project of ICN. It uses an interest packet for request generation and a data packet for interest satisfaction. It updates pending interest table (PIT) and forward information base (FIB) entries according to the communication process. Due to the high mobility of vehicles and unpredictable location in VANETs, the content centric network (CCN) is a decent alternative to overcome the previously specified problems, as each vehicle has a built-in cache to satisfy the requests at any location. For this purpose, it proposes unique PIT and FIB headers to maintain entries during communication to reserve paths. In addition, there are various VANET protocols that have been proposed recently to overcome mobility issues, minimize communication delay, and ensure efficient communication [4; 7; 10; 11]. Various cluster-based routing protocols have been proposed to group vehicles based on common interests [12].
