A Seamless Vertical Handoff Scheme
First International Conference on Wireless Internet (WICON'05), 2006In the last decade, many new wireless communication systems have been proposed and developed. These communication systems have different extends of network coverage and form a hierarchical overlay network. A vertical handoff is thus occurred when moving between these different communication systems.

Vertical Handoff Mechanisms in VANET
Proceedings of the Second International Conference on Information and Communication Technology for Competitive Strategies, 2016Vehicular ad-hoc network is a modern paradigm for vehicular communication on the move. Vehicular-ad-hoc network is a technology that facilitates three types of communication (vehicle-to-infrastructure, vehicle-to-vehicle and vehicle-to-person) and improves the quality of service of these communication categories.

Optimizations for vertical handoff decision algorithms
2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004Future wireless networks must be able to coordinate services within a diverse network environment. One of the most challenging problems for coordination is vertical handoff, which is the decision for a mobile node to handoff between different types of networks. While traditional handoff is based on received signal strength comparisons, vertical handoff

TCP with Explicit Handoff Notification for a Seamless Vertical Handoff
2008This paper proposes a new variant of TCP for seamless vertical handoffs in heterogeneous wireless/mobile networks, which exploits explicit handoff notifications to alert handoff types and packet losses due to handoffs for efficient congestion control and packet error recovery mechanisms.

Vertical handoffs in wireless overlay networks
Mobile Networks and Applications, 1998No single wireless network technology simultaneously provides a low latency, high bandwidth, wide area data service to a large number of mobile users. Wireless Overlay Networks – a hierarchical structure of room-size, building-size, and wide area data networks – solve the problem of providing network connectivity to a large number of mobile users in an

Vertical Handoff between WWAN and WLAN
International Conference on Networking, International Conference on Systems and International Conference on Mobile Communications and Learning Technologies (ICNICONSMCL'06), 2006This paper reports on the design and implementation of an IP-centric vertical handoff decision algorithm and execution scheme between a wireless wide area network (WWAN) and a wireless local area network (WLAN) as part of the "IP-centric Field Workforce Automation". The project aims to ensure free movement of field workers between networks while always

On The Vertical Handoff Decision for Wireless Overlay Networks
2006 International Symposium on Computer Networks, 2006The evolution of mobile multimedia services outlines a trend towards the coexistence of wireless overlay networks. These networks have overlaid coverage areas and are composed of a hierarchical structure ranging from in-room to in-building, campus, metropolitan, and wide-areas.

A Methodology for Evaluating Vertical Handoff Decision Mechanisms
Seventh International Conference on Networking (icn 2008), 2008The proliferation of wireless technologies and their ever increasing popularity and pervasiveness made it possible to have mobile terminals (MTs) equipped with a myriad of network interfaces. It is then becoming essential to offer vertical handoff solutions where users can move among various network types efficiently and seamlessly.

P-Handoff: a protocol for fine grained peer-to-peer vertical handoff
The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003This paper describes a novel approach to using peer to peer wireless links, such as IrDA, Bluetooth and 802.11b. We explain the concept of wireless diversity and its impact on developers and users. We also explore the limitations of classical vertical handoff protocols, such as the need of an infrastructure.

A Dynamic Interface Activation Scheme for Vertical Handoffs
2008 International Conference on Networking, Architecture, and Storage, 2008This paper presents a dynamic interface activation scheme for making vertical handoff decisions. Interface activating interval is intelligently adjusted according to the actually varying network conditions. The simulation results demonstrate that the proposal succeeds in trading off between interfacespsila activating interval against deciding ...
