Abstract	In the vehicular ad hoc network, the variation in the network is increasing rapidly due to convergence of cities into a smart city. With the rapid increase of vehicles, many problems arise in the network such as cost, scalability, security and trust management. To address these problems, we proposed the trust management system through blockchain based authentication of the vehicles by assigning unique identification. If still malicious vehicles exist in the network, trust is achieved by calculating the data that is sent from the vehicles so that network does not get stuck due to malicious data. In addition, we also proposed the crowdsensing concept using vehicles' sensors data and we minimize the cost of deploying the sensors and also optimize the density of area with respect to chance minimum occurrence of vehicles. We performed these solutions on the etheriam environment. vehicle to vehicle and vehicle to infrastructure communication got secured from malicious vehicles and malicious data. In crowdsensing, cost is reduced as compared to the wireless sensor network. © 2019 IEEE.
