Abstract

To reduce the bandwidth needed for broadcast data to be transmitted in an ad-hoc communication network, such as an Intelligent Transportation System (ITS) inter-vehicle communication network, it is proposed to structure the data into several "layers", each containing more general information. As each packet is hopped through the network the amount of data to be transferred decreases according to a predetermined "cost function". By computer simulation it was shown that the bandwidth required to achieve packet reception rates from the same number of vehicles can be reduced to less than one third of that required for non-layered data structures, depending on the number of terminals in the network. In addition a packet structure similar to IP packets is proposed which will enable easily integration of multimedia transmissions into vehicle to vehicle communications.
