Mobile users (MUs) want to be provided with undisrupted network services when they navigate on the Next-Generation wireless networks (NGWNs). For that, interlocking with a heterogeneous network is important, but there have been few studies on the method for guaranteeing global mobility. Thus, this paper proposes the Proxy-LMA technique, the mobile IP-based global inter-networking system, to enhance...
Cost-effective mobility management for roaming mobile users is very important in providing seamless service on next-generation wireless networks (NGWNs). Various IPv6-based mobility management schemes have been developed which are directly involved with data transfer from Mobile Node (MN). In this paper, two methods for analyzing mobility management schemes are proposed and the signaling transfer...
In next-generation mobile networks (NGWNs), seamless service for users and handoffs between heterogeneous networks must be taken into account. In this paper, we propose a seamless proxy-based handoff scheme using the PMIPv6-based proxy model, which is able to improve the performance of handoffs in sensor-based mobile networks. Our scheme can efficiently support IP-based seamless mobility by reducing...
In next-generation wireless networks, provisioning of IP-based network architecture and seamless transmission services are very important issues for mobile nodes. For this reason, a mobility management mechanism to support global roaming is highly regarded. These technologies bring a broader life by using a global roaming account through the connection of multiple devices or technology to mobile users;...
Korea started Terrestrial Digital Multimedia Broadcasting (T-DMB) service in May 2005. As of December 2006, T-DMB service in South Korea consists of, 7 TV channels, 12 radio channels, and 8 data channels. These days T-DMB services are getting much more. TPEG service is one of variable services. It is important and useful for driver to reach a destination faster and easier. We introduce TPEG decoder...
