— 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 discrete event simulator OMNeT++, that is programmed in C++, shows a steady growing popularity. Due to its well-structured nature, it is easy to understand and easy to use. A shortcoming of it, however, is the limited number of available simulation models. Especially, for network simulations a validated TCP implementation was missing. In order to avoid(More)
The tussle between reliability and functionality of the Internet is firmly biased on the side of reliability. New enabling technologies fail to achieve traction across the majority of ISPs. We believe that the greatest challenge is not in finding solutions and improvements to the Internet's many problems, but in how to actually deploy those solutions and(More)
— We present a novel end-to-end QoS architecture which enables seamless services over heterogeneous wireless access networks. We discuss the main architectural approaches and design issues of mobility-aware QoS signaling in IP networks. Then we introduce a QoS signaling architecture that integrates resource management with mobility management. It is based(More)
As mobile nodes move to new links, they need to resume their communications in a timely fashion. To communicate, IPv6 nodes need to complete router discovery, address auto-configuration, and other tasks. Unfortunately, this depends on prior completion of the Multicast Listener Discovery (MLD) protocol, introducing a mandatory delay of up to one second. This(More)
