Abstract: One of The major drawbacks for mobile nodes in wireless networks is power management. Our goal is to proposed a power control scheme that will help minimize energy consumption by appropriate adjustment of vehicles transmitter power, reduce network congestion, improve quality of service and collision avoidance in vehicular networks. Some of the importance of power control (PC) is improving spatial reuse, and increasing network capacity in mobile wireless communications. In this simulation we have evaluated the performance of existing rate algorithms compared with ACARS. Results show that ACARS is able to minimize the total transmit power in presence of of propagation processes and mobility of vehicles, by adapting to the fast varying channels conditions more than the other algorithms, which has some applications in vehicular networks as mentioned above.
