an improved method to evaluate the vehicle's encounter with events in the vanet with the approach of developing non-linear methods

Data exchange between vehicles as network nodes, like other ad-hoc networks, due to the lack of stability infrastructure and central management, and the complete distribution of the network platform, have led to attract many parts of today's researches. in this article, an improved method has been presented in order to evaluate the encounter of the vehicle with the incident, and the interaction of data related to the incidents for use in the vehicle ad-hoc networks. the proposed method has been developed based on the basic indicators of evaluating the node's encounter with events in vehicle ad-hoc networks and has been strengthened based on the advantages and capabilities of fuzzy logic, so that the desired and expected result is obtained from the output of the set. in order to evaluate the performance of the proposed method, developments and implements were based on the opnet simulator and this method was compared with the vespa and vespa-dm methods as the most important researches in this field. the simulation results indicated the superiority of the proposed method over past researches.
