Before revision:  Using the current context that the vehicle operates in (e.g., speed, direction, and application requirement), ECPR adjusts the transmit power of the messages  to reach the desired awareness ratio at the target distance while at the same time controlling the channel load using an adaptive rate control algorithm.
After revision:  Studying various operational conditions (e.g., speed, direction, and application requirement), ECPR adjusts the transmit power of the messages to reach the desired awareness ratio at the target distance while at the same time controlling the channel load using an adaptive rate control algorithm.
