I. Introduction
Today, IT hardware and software are involved in 90% of automotive advancements. Future innovation will focus mostly on VANET applications for safety and security and the variation between them is shown in fig. 1. Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication are the two methods available in the Vanet (V2I). The Internet of Things (IoT) is the internet-enabled operation of significant machines, vehicles, and other items. It is made up of embedded systems with sensors, actuators, and network connectivity that allow for the collection and exchange of data [5]. WSN(Wireless Sensor Network) uses widely dispersed sensor nodes to keep an eye on the environment. Using multi-hop transmission, the sensed and gathered data is delivered to the user via the sink node. The design of a sensor node is subject to a number of limitations, including those related to processing speed, memory, and battery life. The network lifetime (NL) will decrease if the sensor nodes use energy inefficiently, hence the components of the sensor node and the protocols regulating the network must be ideally designed to increase the lifetime of the network by lowering energy consumption. [3]. In vehicle ad-hoc networks, one of the biggest issues is safeguarding the anonymity of the location (VANETs). Although standardization organizations like IEEE and ETSI have established a pseudonym-based strategy to address this issue, an effective method for managing and altering pseudonyms is still a difficulty [7]. An effective Vehicle-To-Infrastructure (V2I) communication signature technique using Identity-based Conditional Privacy-Preserving Authentication (ID-CPPA) and a bilinear map. As opposed to map-to-point hash functions, this technique use universal one-way hash functions. This improves the speed and accuracy of the RSU’s signature and message verification processes. In addition, our ID-CPPA signature technique offers batch signature verification, which lowers the computational burden on the RSU and enables it to validate a significant quantity of traffic-related messages from numerous cars in locations with high traffic density [10]. In terms of communication systems, wireless technology has received the greatest attention, and communication strategies have never been used without taking the operation of the antennas into consideration. The suggested antenna has good coverage and increased power for both indoor and outdoor Long Term Evolution (LTE) areas. The antenna operates in both the lower and higher frequency ranges of LTE band 7 (2.6 GHz) and band 3. (1.8 GHz) [13]. In research and the creation of smart cities, VANETs are a developing technology. The adoption of numerous technologies and protocols, including SRMA/PA [4], allows for the best possible management of traffic congestion. A VANET with an effective charging information transmission mechanism is taken into account while analyzing the real-time traffic in a particular area. Additionally, a more effective local charging data relaying approach is used to increase the charging packet delivery ratio and reduce network overheads [8].
