- Abstract
- To provide the seamless multimedia streaming service for mobile users, both performance of the mobile device and bandwidth constraint of the wireless network should be considered. Recently, in order to solve these problems, the QoS adaptive architectures as well as additional features are being devised. In this paper, we designed and implemented a hybrid architecture-based mobile media streaming system under the Linux environment. The proposed system features as follows. First, a hybrid architecture which complements shortcomings of the static and dynamic architectures is presented. The hybrid architecture is able to maximize the proxy utilization rate by dividing the proxy functions into computation oriented tasks and disk access orient tasks. Second, a callback based resource monitoring scheme that efficiently manages resource of the proxy was proposed. Third, the working time prediction module is added to choose exactly the proxy which finishes the task earlier than others. The experimental results demonstrate that our system decreases not only the user-perceived latency, but also the proxy overload. Furthermore, it has an advantage of reducing the traffic between the proxy and the system manager. © 2007 IEEE.
