The emergence of 5G technology has opened new possibilities for communication systems, particularly in the context of ad hoc networks. This paper explores the concept of 5G-AdHoc, which aims to enable Ultra-Reliable Low Latency Communication (URLLC) in ad hoc networks. We begin by introducing the fundamentals of -AdHoc technology and the challenges it addresses in providing URLLC capabilities. We 5G discuss the architecture and key components of 5G-AdHoc networks, along with the underlying technologies that enable URLLC. Performance evaluation metrics and use cases are examined to showcase the benefits and practical applications of 5G-AdHoc URLLC. The summary focuses on how 5G's URLLC capabilities ensure stability and efficiency in vehicle clusters, with one scenario showcasing reliability and low latency and another emphasizing scalability and continued reliability. Overall, URLLC plays a crucial role in coordinating connected vehicles within 5G networks for smooth operations in various scenarios. Furthermore, we delve into security and privacy considerations crucial for the deployment of 5G-AdHoc networks. Finally, we outline future trends and potential developments in 5G-AdHoc technology, highlighting its significance in advancing communication systems for diverse applications.
