Performance comparisons of inter-vehicle communication networks - including the modified V-PEACE scheme proposed

摘要

In this paper, conventional schemes such as ALOHA, non-persistent CSMA and the V-PEACE scheme for IVCN (Inter-Vehicle Communication Networks) are compared including investigations of information contents and a required frequency bandwidth. Moreover, the modified V-PEACE scheme representing vehicle's precise position is proposed and compared with the conventional schemes. Results of the comparisons show that the V-PEACE and the MV-PEACE schemes are superior to the other schemes in terms of the frequency efficiency, and that the MV-PEACE scheme that requires 2.8 [MHz] can represent vehicles' positions more accurately than the V-PEACE scheme that requires 0.2 [MHz] can.
