Development of Communication Technology on VANET with a Combination of Ad-hoc, Cellular and GPS Signals as a Solution Traffic Problems

Traffic problems can be solved by applying the VANET systems. But the challenge is that VANET WIFI communication between devices must run quickly and efficiently because the nodes are fast moving vehicles. For this reason, the selection of WIFI devices and the quality of the signals that are the media of communication on the VANET must be considered properly. The utilization of Ad-hoc, Cellular, and GPS signals must be arranged according to their needs and portions.
