摘要: Two types of safety messages, beacons and event-driven emergency warning are playing a key role in many safety-related applications Intelligent Transportation System (ITS), which designed for improving road traffic efficiency. Every vehicle on the periodically sends to notify neighbors its position, speed, direction acceleration. When there is an situation, messages emitted. As same Control Channel used by these two dense network when congestion happens, it necessary reduce beacon load improve channel condition adjusting transmit parameters. solution problem overloading channel, this paper proposes evaluates adaptive control scheme adjusts transmission frequency according current condition, while considering appropriate accuracy status information updating. To appraise algorithm, several simulations performed. Simulation results demonstrate promising scheme.
