Performance Enhancement of Vanets Using Fuzzy Logic and Network Coding
Vehicular Ad hoc Networks (VANETs), a sub class 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, due to
continuous vehicle movement, providing a reliable and efficient multi-hop broadcast service in VANETs is challenging.
Therefore, we propose a scheme 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 using 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 provide high packet dissemination ratio.
