In this paper, we propose a mobility management scheme with Quality-of-Service(QoS) support for heterogeneous multihomed mobile node. With this scheme, the multihomed mobile node can move between networks seamlessly and at the same time, utilize all available links based on the QoS requirement. Session Initiation Protocol(SIP)[1] is used in session(More)
Rapid development has equipped mobile devices with heterogeneous wireless access capabilities. A lot of work has been done on WLAN-3G integration to support seamless connectivity and global roaming. Most recent research trends focus on interwork gateway or intersystem roaming framework. In this paper, we introduce an application framework providing seamless(More)
In recent years, wireless communication technologies have been pervasive. We have many wireless options to connect to the Internet: IEEE 802.11 WLANs, GPRS, UMTS and many other competing technologies. These wireless standards were designed independently of each other. Hence, these standards do not specify a common solution to perform connection handover(More)
