IEEE 802.16e is a Worldwide Interoperability Microwave Access (WiMAX) standard that supports mobility. Handover is one of the most important factors that affect the performance of a WiMAX network. Various handover schemes have been proposed and implemented. In this paper, we propose DualTrigger Handover (DTHO) algorithm for WiMAX networks. The proposed handover algorithm depends on the computat...

Stream Control Transmission Protocol (SCTP) is a new end-to-end transport protocol, which can be used to support the mobility of mobile terminals. This paper describes a framework of SCTP handover and analyzes the handover latency for the single-homing mobile terminals. We then show the experimental results of the SCTP handover in terms of the handover latency and throughput for the two differe...

Proxy Mobile IPv6 (PMIPv6), a network-based localized mobility protocol, allows a mobile node (MN) to move around within the same PMIPv6 domain by keeping the same IP address. However, PMIPv6 does not support the global handover since it supports only an intra-domain handover. To support the global handover, MNs need to load the protocol stack for the global mobility. Our proposed scheme enable...

The first part of this paper presents a novel scheme for handover provisioning in wireless asynchronous transfer mode (W-ATM) networks based on in-band signaling. First, the network architecture and principles of in-band signaling are described, discussing advantages and interaction with other procedures and signaling techniques. Then, loss-free protocols for the handover procedures are present...

In this paper a handover functional model and corresponding functionality description in SDL for the IN/UMTS concept for third generation mobile systems protocol development is presented. The model is based on ETSI NA-61301 [1] handover functional model. The main focus is on the introduction and specification of necessary Functional Entities for control and execution of the switching function f...

This document describes Media-independent Pre-Authentication (MPA), a new handover optimization mechanism that addresses the issues on existing mobility management protocols and mobility optimization mechanisms to support inter-domain handover. MPA is a mobileassisted, secure handover optimization scheme that works over any link layer and with any mobility management protocol, and is most appli...

Dense deployment of femtocells in mobile wireless networks can significantly increase the amount of handover initiations. This paper analyzes new approach to elimination of redundant handovers. The innovative way dynamically updates current value of techniques commonly used for elimination of redundant handovers. The goal is to investigate the efficiency of two handover elimination techniques, ...

In mobile Internet, a handover may result in significant degradation of transmission performance. Especially in a shared medium wireless network, handover traffic which moves into a new wireless access network competes with existing traffic for available bandwidth of shared medium wireless channel. This interaction between handover traffic and existing traffic causes significant performance deg...
