In recent years, because techniques of network communication have highly developed, the related applications has been used in many different area. IEEE 802.11 standard was formulated at 1997, and Wi-Fi alliance is formed in 1999. Today, IEEE 802.11 is the general standard in industry.
In this paper, we use Wi-Fi as the interface in transmission to simulate that using the event data recorder with Wi-Fi interface to connect with the main center system and send the image to the screen in a car. Unlike the wired transmit solution, there is a problem that power consumption in wireless transmission. Therefore, we presented an algorithm to make the balance between efficiency and power consumption. We will explain that how to reduce the power consumption but keep real time reaction and make to optimization in following chapter.
