# Road to Efficiency: V2V Enabled Intelligent Transportation System
## 3 Related Studies  
Tracing the historical evolution of V2V communication reveals its progression from conceptualization to implementation. A paper by [PERSON] et al. [32] considers a detailed analysis of existing literature and research papers concerning security protocols and techniques for vehicle-to-vehicle (V2V) communication. These entail a comprehensive review of some major facets that comprise authorization and authentication, cryptology and ciphers, key management and distribution, and lastly, intrusion and detection systems. The paper is likely to contain changes and advice; however, comparisons with real-life applications and analysis of effectiveness are missing. Another limitation of this type of study is that the improvements that were proposed would have to be implemented and tested in practice. The study by [PERSON] et al. [33] makes a unique contribution to the field of VANETs because it aims to cover most aspects of VANET applications, networking, and issues in a single survey. However, the paper predominantly considers the strategic and main categories, which is insufficient to explore the details to be implemented at the V2V level. Moreover, while the integration of evolutionary technologies with V2V is described in sufficient detail, more concrete examples and real-life experiments can be useful to support the theoretical analyses and introduced solutions. [PERSON] et al. [34] survey reviews on P2P applications for VANETs, addressing challenges like broadcast storm problems, network partitioning, and temporal fragmentation. The paper also discusses research issues related to implementing P2P techniques in VANETs but acknowledges the limitations in V2V networks and ITSs. The conceptual frameworks lack implementation details and are not empirically proven or tested in real scenarios, making their applicability in actual V2V networks questionable. Further research is needed for practical, scalable, and reliable solutions. The paper by [PERSON] et al. [13] proposes the application of the Internet of Vehicles (IoV) as an extension to conventional VANET for the 5G/B5G world. It emphasizes the need for VANETs to accommodate vehicle automatic control and intelligent road information services. The paper presents a literature review on IoV Midlands, discussing VANET technologies, network architectures, and IoV applications. However, the paper has limitations, such as a lack of practical experience, scalability, and security and privacy aspects. Further research is needed to overcome these limitations and advance the understanding of IoV in vehicular communication systems. The study by [PERSON] et al. [35] discusses the introduction of MANETs and introduces VANET as the best way through which communication and the flow of traffic on the roads could be achieved. It focuses on the strength that contains low jitter, reduced transmission delay, and proper mobility management of the VANETs, which are, in general, essential for ITSs. However, this document is silent on prospects such as risks such as security threats, V2V implementation challenges, and compatibility of the relatively new V2V communication with established structures that may inhibit its large-scale usage. Moreover, it lacks information about the compatibility of the various communication infrastructures and the effect of several traffic loads on V2V networks. Further elaboration on these limitations would help to give better insight into the issues that must be addressed when considering V2V communications and their integration into VANET structures [36]. A study by [PERSON] et al. [37] provides a distinct trend in the development of automotive V2X technology: the V2P communication system, which has the potential to improve the safety and comfort of vulnerable road use groups, explains Vehicle-to-Pedestrian (V2P) systems in a nutshell, speaking of different communication technologies and interaction modes used to increase pedestrian security.
