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)
Handoff latencies affect the service quality of real-time applications of mobile users. With Mobile IP (MIP), the handoff latency highly depends on the distance, i.e. delay, between Home Agent (HA) and Foreign Agent (FA). Hierarchical MIP (HMIP) minimizes handoff latencies but depends on additional network elements introduced on the path between HA and FA.(More)
One of the main challenges in future ldquoAll-IPrdquo networks is to guarantee seamless mobility with minimal or even without any interaction from the user. The Network-based Localized Mobility Management (NETLMM) working group is currently developing Proxy MIPv6 (PMIPv6), which tries to support terminal mobility without involving the MN. This paper(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)
Latency during handoffs affects the service quality of real-time applications. This paper describes the Mobile IP Fast Authentication protocol (MIFA) and introduces a simple analytical performance model to evaluate this protocol compared to Mobile IP (MIP) and Hierarchical Mobile IP (HMIP). Our performance study shows that the handoff latency of MIFA is(More)
A major challenge pertinent to Long Term Evolution (LTE) systems is the development of self-organized PCI assignment solutions. This paper focuses on this challenge and proposes a new distributed and self-organized solution named Stable Graph Coloring (SGC) scheme. The proposal introduces a temporal PCIs sub-range for newly switched on eNBs, minimizes the(More)
An important challenge for "All-IP" wireless networks is the development of solutions for seamless mobility. A lot of mobility management protocols have been developed to match real-time requirements in these networks. Estimation of the cost, resulting from deploying these protocols, is very important. So far, this cost are estimated by developing a(More)
Deployment of future ALL-IP mobile communication networks requires overcoming many challenges. One of them is how to provide QoS guarantee in such high dynamic environments. Basic principle is to couple between mobility and QoS solutions, so that handoffs are executed and simultaneously resources reserved. Most approaches doing such coupling optimize the(More)
