Abstract
A method and device for dynamically changing transmission parameters of broadcast messages transmitted and received by a mobile unit. The method and device include monitoring transmission channel characteristics; dynamically adjusting the transmission parameters of a message based on the monitored transmission channel characteristics; and broadcasting the message using the adjusted transmission parameters. The transmission parameters may include one or more of transmission power, error code rate, and modulation rate. The transmission channel characteristics include one or more of the group consisting of received message density, channel congestion, detected number of message collisions, and signal to interference ratio.
