Design and implementation of division-based broadcasting using ns-3

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. However, there are two problems in conventional evaluation environment using the computer simulation. First, since users need to modify the simulation program according to the change of evaluation situation, they can not accurately calculate the value of the evaluation result. Second, in conventional simulation program, it is difficult to evaluate the scheduling method considering the actual network environment. In this paper, to solve these problems, we design and implement the simulation environment using NS-3 network simulator in division-based broadcasting. By using NS-3, we can evaluate the scheduling methods considering various situations assumed in actual network environment.
