| Abstract | The Internet of Vehicles (IoV) plays a crucial role in the development and implementation of smart city initiatives by enhancing transportation systems, improving road safety, and optimizing urban mobility. The main challenges in smart cities are to minimise interference from Vehicle-to-Vehicle (V2V) pairs and Vehicle-to-Infrastructure (V2I) users to improve the overall throughput and efficiency of IoV systems. In this chapter, the power allocation problem is investigated to minimise the interference and maximise the throughput of V2V pairs for Non-orthogonal multiple access (NOMA)-enabled IoV system. The maximisation problem is non-convex in nature and hence difficult to solve directly. Therefore, the maximisation problem is converted into a convex one by using the Lagrange Multiplier technique. The Hungarian method is applied for reuse pair matching to enhance the spectrum efficiency of the system. Hence, the throughput of V2V pairs is analysed in terms of the Signal-to-interference noise ratio (SINR) of V2V users, and transmit power of V2V users. The effect of the Successive Interference Cancellation (SIC) parameter is also investigated on V2V throughput for different values of transmit power. Furthermore, the proposed scheme achieves a higher throughput improvement of 39.5 % in comparison to the existing scheme. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025. |
