Performance Study of Economical and Environmentally Friendly Geocast Routing in Vehicular Networks

Economical and environmentally friendly geocast (EEFG) uses traffic signals to communicate with approaching vehicles. The communication can be signal-to-vehicle (TLS2V) and vehicle-to-vehicle (V2V). Based on the information sent, the vehicle receiving the message adapts its speed to a recommended speed $(S_{R} ) $, which helps the vehicle reduce fuel consumption and emissions. Our previous paper entitled “Optimization of Fuel Cost and Emissions Using V2V Communications” develops a model to determine the optimum $S_{R} $. It also proposes heuristic expressions to compute the optimum or near-optimum $S_{R}$.
