Seamless Proactive Vertical Handover Algorithm

2011 Eighth International Conference on Information Technology: New Generations, 2011
At present, none of the wireless access or mobile cellular network technologies provides ubiquitous coverage and the complete set of services required by the users. Therefore, the next generation of wireless networks i.e. 4th Generation (4G) network aims at the integration of these distinct yet complementary networks to satisfy user requirements and to

An Evaluation of Vertical Handovers in LTE Networks

2012
One of the key requirements of the LTE core network is to provide seamless mobility and session continuity at the IP layer across multiple access networks - 3GPP and non-3GPP. Although this can be achieved in LTE networks using Proxy Mobile IPv6 (PMIPv6), two key limitations still exists - handover latency and high packet loss.

Vertical handover among broadcast networks

2009 6th International Symposium on Wireless Communication Systems, 2009
In this article we propose strategies for optimization of vertical handover among broadcast networks. The specific technologies of DVB-H and UMTS/MBMS are taken into account for the modelling of technological parameters including energy consumption and frame loss.

A Multihoming-Based Vertical Handover Scheme

2012
This paper proposes a multihoming-based vertical handover scheme. Mobile nodes must have several radio interfaces to support vertical handover in heterogeneous wireless networks. In this paper, we consider each interface of a mobile node has its own protocol stack with physical, data link, and network layer. When a mobile node moves to a different type

An energy efficient vertical handover decision algorithm

2014 IEEE Globecom Workshops (GC Wkshps), 2014
As wireless communications evolve towards heterogeneous networks, mobile terminals have been enabled to handover seamlessly from one network to another. At the same time, the continuous increase in the terminal power consumption has resulted in an ever-decreasing battery lifetime. To that end, the network selection is expected to play a key role on how

Velocity aware vertical handovers

2009 2nd International Symposium on Applied Sciences in Biomedical and Communication Technologies, 2009
A wireless heterogeneous network consists of various wireless networks such as Worldwide Interoperability for Microwave Access (WiMAX), Wireless Fidelity (WiFi), cellular networks etc. Vertical handover (VHO) is a procedure that enables continuous seamless communication in these heterogeneous systems.

New Developments in Vertical Handover Based on Media Independent Handover Standard

Wireless Personal Communications, 2014
This paper proposes an enhanced approach for implementation of Media Independent Handover (MIH) information services (MIIS) based of the combination of a hierarchy of information servers and prediction of next point of attachment (PoA). While other recent proposals were validated only by simulations, we evaluated the implemented system with a real ...

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.

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 ...
