The Design And Realization Of The Wireless Video Monitoring System Based On Embedded Linux And CDMA1X

With the rapid development of mobile communication technology, mobilemultimedia communication has turned into a hotspot in the field of monitoring. Thisthesis has mainly researched one application combining the Embedded LinuxOperation System (ELOS) and CDMA1X technology to realize wireless videomonitoring system.By researching the software technology and hardware technology in embededsystem, going deep into master the principle of ELOS, building embeded Linuxkernel to satisfy application, studing the CDMA1X technology in the application inthe ELOS, a kind of general model of collecting and transmitting video by wirelesswhich based on embedded Linux and CDMA1X. was put forward in this thesis.The main study in this thesis is to realize reliable and real-time videotransmission from end to end. A double-channel selected mechanism based on packetloss rate was proposed. It can improve transmission quality and reliability by ascheduling algorithm of wireless double-channel on network layer.As the simulation experiments have shown, this mechanism applied todouble-channel can increase linearly transmission rate of video stream, and enhancesits stability. It also has several advantage such as credibility, cheap, real-time andhigh transmit rate and easy to carry out reserved target.
