Study of Multiple Interface Control and Dynamic Delivery Model for Seamless Mobile Transportation

399 Abstract—We propose a seamless IPTV transport technology of mobile device. This technology uses multiple interfaces of wireless communication on mobile device. This proposal for transportation of mobile IPTV contents is more mobile and adaptable than other wireless technologies that are currently being used. Algorithm of proposed technology is as follow. When the signal strength of the connected wireless network interface of mobile device is getting lower than specified level, another wireless network interface is connected to continue downloading the IPTV contents in advance. Another connection is maintained until the signal strength of the first connected interface is stable or the interface is connected to another base station (or AP) that have good signal strength. For more seamless services, we consider classifying the packets of mobile IPTV and using dynamic content quality select techniques. Dynamic content quality selection is based on notifying transfer rate to the content delivery network (CDN) server. The proposed technology is expected to use efficiently with both mobile IPTV and the transportation of mobile P2P/P4P. Mobile phones are increasingly becoming the main communication tool for private and business use, and 2010 promises to offer users a number of innovations. Smart phones are better placed than the standard mobile phone to deal with these advances because of their large display screens and speedy Internet connections. Consumers demand more mobility because of these advances, so that they could communicate with each other by Twitter, watch videos on YouTube, and in the car, train, or anywhere. Although access to office activities is what they want on the road such as mobile messaging and email functions, they also want social network service (SNS) on the mobile device like Facebook, MySpace, Twitter and etc. The other service needs more mobility than the former is multimedia service such as mobile IPTV. Multimedia services on mobile devices should ensure that the seamlessness by adaptive network connection. Nowadays, mobile devices have two or more interfaces for wireless network. For example, iPhone of Apple has Wi-Fi, WCDMA and Bluetooth interfaces. Multiple interfaces have become common overall in latest mobile devices. Most applications use single interface because of several reasons. The biggest reason is the absence of multiple interface infrastructures. Seamless multimedia services could be provided by multiple interfaces. IPTV is no longer a new idea nowadays and iswidely used to provide digital television services usingthe Internet Protocol.IPTV services combine the voice over IP(VoIP), video on …
