Vehicle-to-vehicle anti-collision system and method using power levels

Abstract

Device, system and method, in a vehicle communication system, of managing transmitted power levels among a group of transmitters so that the effective range of the group is approximately the same for members of the group. Various embodiments include transmitting a message comprising a currently used transmit power and a recommended power level. Embodiments include algorithms for varying transmit power levels subject to various criteria. Such criteria include the number of vehicles in the range, the size of the range, available wireless bandwidth. Unique features of some embodiments include the use of broadcast messages, and messages free of IP addresses and MAC addresses.
