Handoff latency affects the service quality of real-time applications. Mobile IP presents the standard mobility management protocol to support the mobility in IP-based systems. However, mobile IP is not adequate for delay sensitive applications. The mobile IP fast authentication protocol (MIFA) is proposed to avoid the problems of mobile IP and to match the(More)
Latency during handoffs affects the service quality of real-time applications, therefore the developing of mobility management protocols is a major challenge in the wireless network. In this paper we propose a fast and smooth handoff scheme called MIFA (Mobile IP Fast Authentication protocol), which reduces the latency of re-authentication and(More)
It is nowadays well known that All-IP networks will be the future B3G networks. However, in order to make these networks as good as 2 or 3G networks with respect to the performance, many challenges have to be faced. One of the main challenges is the developing of suitable mobility solutions to support seamless and fast movement in the network. Mobile IP(More)
Currently we see a discussion on the transition from ATM-based transport to IP transport in the UMTS Terrestrial Radio Access Network (UTRAN). Issues that result from the transition to IP are QoS, esp. delay, jitter, loss, bandwidth guaranties and in sequence delivery of packets for voice traffic. The paper compares two solutions for future UTRANs, native(More)
The paper provides a proposal for an MPLS-based transport network for future Radio Access Networks (RANs) and compares this with a regular IP-based transport network. Our MPLS-based approach takes into account the specific needs of current and future RANs especially with respect to QoS requirements and flexibility. In the paper we compare the MPLS-based(More)
