Neural networks for adaptive vertical handover decision

2007 5th International Symposium on Modeling and Optimization in Mobile, Ad Hoc and Wireless Networks and Workshops, 2007
This paper focuses on mobility management between heterogeneous radio access networks (RANs). A fuzzy multi- criteria vertical handover algorithm enhancing the handover performance is proposed. This algorithm is based on fuzzy logic control. The fuzzy logic controller (FLC) takes into account multiple relevant criteria and rules based on prior ...

Vertical-to-Horizontal Handovers: Architecture and Mobility Management

2007 IEEE Wireless Communications and Networking Conference, 2007
This paper describes a new vision for mobility management in next generation all IP networks. We evaluate the vertical-to-horizontal handover in the proposed integration architecture for the third generation wireless communication (3G) from one side and WLAN 802.11 from the other side.

Vertical Handover Algorithm for Heterogeneous Wireless Networks

2009 Fifth International Joint Conference on INC, IMS and IDC, 2009
Recently, there has been much effort to integrate heterogeneous wireless technologies in order to make overlay networks able to provide mobile users with ubiquitous Internet access. Handover management is still one of the most challenging issues to be solved for seamless integration of wireless networks.

Scalable Mobile Ethernet and fast vertical handover

2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004
The 3G cellular system has infiltrated into the market and the next generation wireless system called beyond 3G is discussed at ITU-R. The beyond 3G system integrates various wireless accesses, including 3G and wireless LANs, and provides an all IP wireless solution to services that take advantage of each wireless communication of the system.

Vertical Handover in Next Generation Wireless Networks

Journal of Next Generation Information Technology, 2012
The next generation wireless networks will support the vertical handoff procedure in which users can keep the connections when they change from one access network to another. Although diffferent vertical handoff decision algorithms have been proposed in the literature recently.

A new approach for optimized vertical handover in NGWN

2015 2nd International Conference on Information and Communication Technologies for Disaster Management (ICT-DM), 2015
One of the challenging issues in Next Generation Wireless Network (NGWN) is achieving seamless Vertical Handover (VHO) while roaming between different technologies such as Wireless Fidelity (Wi-Fi), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications System (UMTS) and Long Term Evolution (LTE).

A QoE-driven vertical handover algorithm based on media independent handover framework

2015 IEEE 11th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2015
The current mobile network has been developed to a heterogeneous network that is coexistence of different wireless networks such as UMTS (3G), WIFI, WIMAX (4G) and LTE (4G). Since the demand of realtime multimedia services has significantly increased in recent years and Quality of Experience (QoE) becomes more and more important to users, any single ...

TCP congestion control with ACK-pacing for vertical handover

IEEE Wireless Communications and Networking Conference, 2005, 2005
In this paper, we discuss TCP congestion control in the future heterogeneous mobile Internet where various access links such as a wireless LAN and a cellular network are integrated. Vertical handover (VH), which is a handover technique between different types of access links, is one of the most important technologies.

Using Link Layer Information for Improving Vertical Handovers

2005 IEEE 16th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006
In this paper we present a solution, which acquires access-technology dependent link layer events and parameters and modifies them to unified form. The solution can be used to enable seamless handovers in wireless networks.
