— The long latency associated with Mobile IPv6's home-address and care-of-address tests can significantly impact delay-sensitive applications. This paper presents an optimization to Mobile IPv6 correspondent registrations that evades the latency of both address tests. An optimized correspondent registration eliminates 50%, or more, of the additional delay… (More)

The fourth generation (4G) of mobile communication networks will provide a multitude of real-time and non-real-time services on top of an IP-based platform. Subscribers can access these services over arbitrary radio-access technologies, including existing WPAN, WLAN, WMAN, and WWAN technologies as well as future air interfaces for broadband wireless access.… (More)
Future mobile networks will offer a great variety of multimedia services. DiffServ is the promising framework standardized by the IETF to enhance the Internet with the essential quality of service. Unfortunately, transaction-oriented applications— the most popular class of applications—are not sufficiently supported yet. Quick Forwarding (QF) has been… (More)
