“…The structure can be extended to include multiple hierarchy levels of FAs beneath the GFA level. However, recursive tunnelling has to be applied, which results in longer latencies and affects the flexibility of the system [24]. [7] proposes a distributed dynamic regional location management scheme for Mobile IP to reduce the overall signaling cost.…”

One of the major challenges for the next generation mobile systems is related to efficient mobilitymanagement issue. In this paper, we propose a new micromobility management scheme, called Micro Mobile MPLS, that supports both mobility and quality-of-service (QoS) management in wireless networks. Our proposal includes two protocol variants. In the first variant, called FHMicroMobile MPLS, we consider the fast handoff (FH) mechanism, which anticipates the LSP (Label Switched Path) procedure setup with an adjacent neighbor subnet that an MN is likely to visit. This mechanism is proposed to reduce service disruption by using the link-layer (L2) functionalities. In the second variant, called FC-Micro Mobile MPLS, the forwarding chain (FC) concept is providedto track efficiently the host mobility within a domain. This concept is more suitable for MNs with high mobility rate. In order to assess the efficiency of our proposals, all underlying protocols are compared. To achieve this, we develop analytical models to evaluate the link usage cost, the registration updates cost, the handoff latency and the packet loss rate. Numerical and simulation results show that the proposed mechanisms can significantly reduce the registration updates cost and provide low handoff latency and packet loss rate under various scenarios.

“…This guarantees the setup of an optimal new path between the domain gateway and the current access router in meshed topologies, in contrast to Hawaii. A more detailed description of MEHROM and a comparison with Cellular IP, Hawaii and MIPv4 Regional Registration, is given in [10,11].…”

“…Nevertheless, for reasons of robustness against link failures and load balancing, a much more meshed topology is preferred. In our previous work [10,11], MEHROM (Micromobility support with Efficient Handoff and Route Optimization Mechanisms) was developed, resulting in good performance, irrespective of the topology, for frequent handoffs within an IP domain.…”

Q-MEHROM: Mobility support and resource reservations for mobile senders and receivers

The increasing use of wireless networks and the popularity of multimedia applications, lead to the need for Quality of Service support in a Mobile IP-based environment. This paper investigates the reservation of resources for mobile receivers as well as senders in combination with micromobility support. We present Q-MEHROM, which is the close coupling between the micromobility protocol MEHROM and a resource reservation mechanism. In case of handoff, Q-MEHROM updates the routing information and allocates the resources for a sending or receiving mobile host simultaneously. Invalid routing information and reservations along the old path are explicitly deleted. Resource reservations along the part of the old path that overlaps with the new path are reused. Q-MEHROM uses access network topology and link state information calculated by QOSPF. Simulation results show that the control load is limited. Moreover, it consists mainly of QOSPF traffic and it is influenced by the handoff rate in the network. Q-MEHROM makes real use of the mesh links and extra uplinks, which are present in the access network to increase the robustness against link failures, to reduce handoff packet loss and to improve the performance for highly asymmetric network loads. Also, attention is paid to the differences between the mobile sender and the mobile receiver scenario.

“…To which extent these requirements are fulfilled is indicated by We developed the micromobility handoff scheme MEHROM [20] [21], which stands for Micromobility support with Efficient Handoff and Route Optimization Mechanisms. This is a per-host forwarding scheme consisting of two phases.…”

Abstract. When today's commuters in the train or in a car want to access the Internet, they see themselves restricted to simple web surfing or e-mail. Interactive multimedia services, like online gaming or video conferencing are still unavailable to them, even with promising new technologies like UMTS or WiMAX. The impact of high bit rate multimedia traffic on the access network and aggregation network is an important topic, that has not been addressed in enough detail before. We designed a network architecture for offering these multimedia services to fast moving users. We refer to the overall network architecture as the FAMOUS network architecture, which consists of two parts: (i) an access network part which has to deal with large number of users, asking for a high bandwidth, while experiencing a high handoff frequency and (ii) an aggregation network part which has to deal with dynamic tunnels of very high bandwidth, while experiencing a low handoff frequency. In this paper, we detail the FAMOUS architecture, together with optimized handoff strategies, an optical switching architecture, a design methodology for dimensioning aggregations networks and automatic tunnel pre-configuration and activation. Moreover, performance results of these mentioned aspects will be presented.
