碩士 === 國立政治大學 === 資訊科學學系 === 101 === Smartphones are more powerful and popular nowadays. We hope to utilize smartphones to develop an interactive radio application, IRIS: Interactive 2.0 Radio System on the Internet over Smartphone. Using this App, a user can create a channel and become a “DJ” to provide the show. Otherwise, he/she can be the audience to choose the radio channel that his/her favorite DJ hosts. The DJ not only provides the music but also can anchor by the microphone on the smartphone. If the audience has any feedback to the DJ, he/she can make a call-in to talk interactively with DJ by the VoIP service. To this end, there is a problem on network transmission over smartphone. Because smartphones are usually behind NAT, it would cause no one to be able to connect to each other directly due to private IPs. Besides, when many DJ provide their shows on the air, it might cause many streaming relays to overload the Server. Therefore, we need to solve the NAT problem and alleviate the loading on the server by deploying a load balancing architecture. The App and the radio system were developed and the results were satisfactory.
