Minimizing hazardous conditions in transportation through wireless sensor networks with VANET

Through facilitating connectivity between automobiles and their surroundings, vehicular ad hoc networks, or VANETs, significantly contribute to improvements in road safety, traffic efficiency, and passenger comfort. Nevertheless, because networks are both open and changing, roadside devices collect vital safety information. By bolstering general security with the use of wireless communication networks (WSNs), this study helps bring about a safe transportation system. The proposed system employs a distributed network of mobile sensors embedded inside the VANET framework to track and detect roadside surroundings. Together, these sensors gather and process information about the movements of vehicles and traffic patterns. The authority, secrecy, integrity, availability of multifunctional safety applications have been implemented through use of V2V (vehicle to vehicle) connectivity and collected data. NS 2.35 platform is used to validate simulated analysis, and it is shown that suggested analysis works well with various transport intelligence systems in ad hoc networks (VANETs). In light of this, deployment demonstrates data confidentiality, integrity, overall network resilience, opening the door to more secure and safe communication. The performance evaluation metrics are quality of service (QoS) for forward collision warning (FCW) and lane change warning (LCW), communication delay (CD) and packet loss rate (PLR) used for this experiment.
