Abstract :
We have constructed a scalable quality of service middleware system, which contains a monitoring user agent client, a monitoring user agent server and a leader agent. A network camera sends video transmission to the smart phone. The video transmission transits through a scalable quality of service server. The monitoring user agent client resides in the smart phone. The monitoring user agent server and leader agent reside in the scalable quality of service server. Both monitoring user agents monitor the video transmission ´s bit-rate. The monitoring user agents transmit their evaluation to the leader agent. Then the leader agent deducts whether to ordain the network camera to scale the quality of service values down or up. The research problem of the paper is to determine a middleware, which improves the control of the video transmission over a mobile system. Our innovative theories are the scalable quality of service middleware system ´s architecture, passive monitoring paradigm, and calculation and deduction methods. The theories endeavor to optimize the video transmission rate to a smart phone over a wireless network. The operability of the constructed prototype indicates that this endeavor is attained. The research is based on the constructive method of the related publications and technologies and the results are derived by the implemented scalable quality of service middleware system.
