An efficient approach for congestion detection and control in VANETs

Vehicular ad hoc network (VANET) is a promising technology that uses a variety of messages to deliver convenience and safety features. VANET has unique characteristics regarding the high speed and variable density of vehicles. The short time for vehicular communication, especially at high speeds, presents difficulties. Channel utilisation, especially for safety messages, is a big issue due to its unique characteristics, which can lead to congestion, higher delays, and energy waste. This problem affects the performance of the VANET as a whole and the efficiency of VANET applications, such as the emergency notification system. This work aims to design a novel mechanism for managing and detecting congestion in VANET to mitigate these issues. The proposed mechanism uses priority-based channel assignment to handle congestion control in VANET. The extensive simulation results demonstrate that the proposed approach effectively addresses congestion, ensuring a more reliable environment for VANET operations.
