In this paper, we propose L3 handover scheme using SIP messages to minimize handover latency and packet loss in a MN with single interface. Packet loss and handover latency arise from L2/L3 association delay and IP configuration delay when the MN transfers internet connectivity from the serving access router to the target access router using legacy terminal mobility mechanisms. Therefore, seamless...
With the rapid growth in the number of mobile subscribers and mobile devices, the demand high-speed Internet access is becoming a primary concern in our lives. Not long ago, the most stable and well known solution of IP-based mobility management is Mobile IPv6 (MIPv6). Even if MIPv6 is a well-known mature standard for IPv6 mobility management support, however, it has revealed some problems such as...
The packets in the Internet are classified by edge router according to the traffic conditioning agreement (TCA) in differentiated services (DiffServ) domain. The core routers forward the packets in different fashion according to the PHB(Per Hop-Behavior). Currently, the QoS during handover is not guaranteed since packet buffering does not consider PHB during the handover in DiffServ domain. To solve...
Proxy Mobile IPv6 outperforms previous mobility protocols have been standardized by the Internet Engineering Task Force. However, Proxy Mobile IPv6 still involves the triangle routing problem in where data packets for the mobile node are delivered throughout inefficient routing paths. To address the triangle routing problem, two different Route Optimization schemes proposed that exclude the inefficient...
Nowadays, it is common that people carry several kinds of portable devices such as cellular phone, MP3 player, and PDA etc. If we assume that these devices build a WPAN (Wireless Personal Area Network) via Bluetooth Piconet, the master node of the Piconet plays a role of MR (Mobile Router) with maintaining connection to Internet via WLAN (Wireless LAN). Thus WPAN with Bluetooth is quite suitable for...
In this paper, we propose a novel network architecture for future Internet to solve both routing scalability and mobility. Our proposal is based on a LISP+ALT architecture to achieve routing scalability in a global Internet scale. We extend the LISP+ALT architecture to provide roaming for global mobility and take a network-based approach for seamless local mobility. Our network architecture for mobility...
