Vehicular Ad hoc Networks (VANETs), a sub group of Mobile Ad hoc Networks (MANETs), are networks that have no fixed infrastructure and instead depend on the vehicles themselves to provide exchange of information. They have potential in enhancing road safety by sharing emergency information to other vehicles in the network. However, because of constant movement of vehicles, presenting a successful broadcast service in VANETs is challenging. Therefore, we propose an approach which uses fuzzy logic, with the help of fuzzy logic tool box in MATLAB software, to choose the forwarding nodes and uses network coding to reduce the number of retransmissions. By means of fuzzy logic, the best forwarding nodes are selected which further transmit the messages. By integrating network coding with the fuzzy logic based forwarding, we significantly reduce the number of required transmissions and thus enhance the efficiency for disseminating messages in VANET system.
