Abstract

To solve the problems of fluctuation of bit rate and packet loss rate based on 3G network wireless monitoring system, on the basis of the existing code rate control strategy, a method based on the packet loss rate and video delay was adopted, and the existing AIMD algorithm was improved so as to meet the requirements of adaptive adjustment. Application results show that the algorithm can estimate the change of network condition correctly and limit the packet loss rate to a very small scale. Comparing with the existing adaptive bitrate adjustment algorithms, the proposed algorithm can achieve better performances in bitrate fluctuation and packet loss rate in the 3G environment．

Key words： 3G network; wireless monitor system; code rate; packet loss rate; adaptive adjustment
