Evaluation of Division-based Broadcasting System over Wireless LAN

Due to the recent popularization of the Internet, continuous media data broadcasting such as audio or video have attracted great attention. Although continuous media data broadcasting can reduce the more necessary bandwidth than conventional on-demand delivery, waiting time from requesting data to playing it increases. In division-based broadcasting, many researches have proposed scheduling methods to reduce the waiting time. Although a division-based broadcasting system has also been proposed to evaluate these methods, this system does not consider wireless LAN environment. In wireless LAN environment, we have to consider the such problems as a communication protocol and a packet loss. In this paper, we implement and evaluate a division-based broadcasting system to solve the problem in the conventional system. In our proposed system, we confirm the effectiveness for reducing the waiting time using the scheduling method.
