Wireless data transmission safeguard mechanism based on network status

摘要

Using open-pit wireless local area networks (WLAN) as a research environment, the time and spatial characters about the information transmission between the vehicle terminal and the server is in depth analyzed. It describes the spatial distribution of wireless network signal strength. In vehicle terminal program, the spatial query method is utilized to obtain the latency time of vehicle location, and then improve data transmission efficiency and vehicle terminal overall resource utilization by reasonable arrangement of various threads and events based on the event-driven.
