Abstract :
A large set of potential applications being designed for intelligent transportation systems (ITS) depend on the broadcasting of information and control packets by roadside infrastructure points to vehicles in their vicinity. This paper considers the transport capacity of broadcast schemes and evaluates and compares the transport capacity of strategies based on time-splitting, frequency-splitting and superposition coding. A proportionally fair broadcast scheduling algorithm is then proposed and its performance compared against other schedulers.
