The next generation networks must support mobility for ubiquitous communication between any two nodes irrespective of their locations. Mobile IP was the first protocol to support mobility. The process of registration in Mobile IP protocol requires large number of location updates, excessive signaling traffic and service delay. This problem is solved by Hierarchical Mobile IP (HMIP) using the concept of hierarchy of Foreign Agent (FA) and the Gateway Foreign Agent (GFA), Mobility Anchor Point (MAP) to localize the registration information. The performance depends upon the selection of GFA or MAP and some key parameters. This chapter discusses several HMIP based mobility management schemes with a comparative analysis of those protocols and proposes an efficient mobility management scheme.

Seamless mobility management of the mesh clients (MCs) in wireless mesh network (WMN) has drawn a lot of attention from the research community. A number of mobility management schemes such as mesh network with mobility management (MEMO), mesh mobility management (M3), and wireless mesh mobility management (WMM) have been proposed. The common problem with these schemes is that they impose uniform criteria on all the MCs for sending route update message irrespective of their distinct characteristics. This paper proposes a session-to-mobility ratio (SMR) based dynamic mobility management scheme for handling both internet and intranet traffic. To reduce the total communication cost, this scheme considers each MC’s session and mobility characteristics by dynamically determining optimal threshold SMR value for each MC. A numerical analysis of the proposed scheme has been carried out. Comparison with other schemes shows that the proposed scheme outperforms MEMO,M3, and WMM with respect to total cost.

VANET Networks are one of the main next generation wireless networks which are envisaged to be an integration of homogeneous and heterogeneous wireless networks. The inter-networking of these wireless networks with the Internet will provide ubiquitous access to roaming network users. However, a seamless handover mechanism with negligible handover delay is required to maintain active connections during roaming across these networks. Several solutions, mainly involving host-based localized mobility management schemes, have been widely proposed to reduce handover delay among homogeneous and heterogeneous wireless networks. However, the handover delay remains high and unacceptable for delay-sensitive services such as real-time and multimedia services. Moreover, these services will be very common in next generation wireless networks. Unfortunately, these widely proposed host-based localized mobility management schemes involve the vehicle in mobility-related signalling hence effectively increasing the handover delay. Furthermore, these schemes do not properly address the advanced handover scenarios envisaged in future wireless networks. This paper, therefore, proposes a VANET mobility management framework utilizing cross-layer design, the IEEE 802.21 future standard, and the recently emerged network-based localized mobility management protocol, Proxy Mobile IPv6, to further reduce handover delay.

This paper is committed to give an overview of the Host Identity Protocol (HIP), to introduce the basic ideas and the main paradigms behind it, and to make an exhaustive survey of mobility management schemes in the Host Identity Layer. The authors' goal is to show how HIP emerges from the list of potential alternatives with its wild range of possible usability, complex feature set and power to create a novel framework for future Mobile Internet architectures. In order to achieve this, the authors also perform an extensive simulation evaluation of four selected mobility solutions in the Host Identity Layer: the standard HIP mobility/multihoming (RFC5206), a micromobility solution (µHIP), a network mobility management scheme (HIP-NEMO) and a proactive, cross-layer optimized, distributed proposal designed for flat architectures (UFA-HIP).

Mobility Management Protocol

Selection of a MIMO (Multiple Input Multiple Output) antenna to achieve high throughput, minimize errors, and optimize data speed is an important design issue. Radio resource management to provide Quality of Service (QoS) in WiMAX involves dynamic scheduling of resources according to the user’s priority, based classes Platinum, Gold, Silver, and Bronze. Mobility and handoff management in WiMAX is another important issue involving location update, signaling traffic and service delay, and call blocking and dropping. This chapter focuses on some issues concerning MIMO configuration to improve transmit diversity, developing an appropriate scheduling algorithm to improve QoS, and presenting a novel mobility management protocol THMIP (Three Level Hierarchical Mobile IP) in IEEE 802.16e environment to reduce signaling cost with respect to QoS parameters like throughput, end-to-end delay, interference, path loss, bit error rate, and Signal-to-Noise Ratio (SNR). For the simulation, the authors use OPNET Modeler and MATLAB.

Set Up

An efficient mobility management for mobile stations plays an important role in mobile communication networks. Two basic operations of mobility management are location registration and paging. A zone-based registration (ZBR) is implemented in most of the mobile communication networks and we consider the mobility management scheme that combines a zone-based registration and a selective paging (SP). We propose a new analytical model that can reflect the characteristics of the ZBR smoothly where location areas of the ZBR are set up so that regions such as roads, bridges, rivers and mountains, where there is relatively little traffic, will constitute their boundaries. We adopt a revised 2-dimensional random walk mobility model to consider such characteristics. In addition, we propose a more efficient division scheme of location area for 2-step selective paging. We evaluate the performance of the mobility management scheme using our mobility model to determine the optimal size of a location area that will result in the minimum signaling traffic on radio channels. Numerical results are provided to demonstrate that our mobility model is useful to evaluate the ZBR more exactly. The results of this study can be used effectively in analyzing and comparing the performances of various mobility management schemes.
