This thesis proposes, describes and validates solutions to enhance mobility in heterogeneous access networks. Wireless access networks have become available almost everywhere and current research strives to make them pervasive. Users having wireless access to the Internet are driving the demand for mobile and heterogeneous solutions where services could be accessed from anywhere, any time and f...

Mobile user tracking is the function of collecting, updating and maintaining information about the location of a mobile user based on situational awareness information. The tracking and connectivity information maintenance mechanism proposed by us is in the form of registration schemes which are of two types{single layer overlapping and multi-layer overlapping. Both types are static, simple to ...

Mobile IP is a simple and scalable global mobility solution. However, it may cause excessive signaling traffic and long signaling delay. Mobile IP regional registration is proposed to reduce the number of location updates to the home network, and reduce the signaling delay. This paper introduces a novel distributed and dynamic regional location management for Mobile IP where the signaling burde...

In the current era, the wireless cellular network is gaining much attention in the network mobility for qualitative service. Towards enhancing the QoS and narrowing the dilemma of network management (location management) an efficient metric-based location management technique is introduced in this paper to capture the current location of mobile subscribers. The attributes of this technique are ...

For a wireless network to effectively deliver services to the mobile users, it must have an efficient way to track them. The location management fulfills this task through location registration and paging. Many location management strategies, such as profile-based scheme (PBS), have been proposed to reduce the signaling traffic caused by the location update and paging. In the PBS scheme, the sy...

While IP is declared as the key technology of the future’s wired and mobile communication, the currently used version of IP, IPv4 itself is not suitable to be used in mobile scenarios. Next generation mobile users require special support to provide connectivity, although they change their place of attachment to the network frequently. The task of mobility management is to provide this support, ...

Hierarchical Mobile IP (HMIP) reduces the signaling delay and number of registration messages to home agent (HA) by restricting them to travel up to a local gateway only. It uses centralized gateways that may disrupt the communications, in the event of a gateway failure, between a gateway and the mobile users residing with underlying foreign agents (FAs) in a regional network. Dynamic mobility ...

This paper presents binary differential evolution based optimal reporting cell planning (RCP) for location management in wireless cellular networks. The significance of mobile location management (MLM) in wireless communication has evolved drastically due to tremendous rise in the number of mobile users with the constraint of limited bandwidth. The total location management cost involves signal...

Location management scheme tracking the location information of a mobile user is required to deliver the incoming calls since the latest wireless communication networks allow dynamic relocation of mobile terminals. In this paper, we propose a mobile locality based location management scheme using the mobility information of mobile users to provide an efficient location management mechanism. In ...
