New Vertical Handover Method to Optimize Utilization of Wireless Local Area Network in High-Speed Environment. [PDF]
In heterogeneous wireless networks, wireless local area network (WLAN) is highly preferred by mobile terminals (MTs) owing to its high transmission bandwidth and low access cost.

A fast adaptation mechanism for TCP vertical handover [PDF]
In this paper we propose a vertical handover mechanism for TCP to deal with the delay and bandwidth change during the handover. The proposed mechanism relies on the interaction between the sender and the receiver during the handover and requires no a prior information of the new path.

Vertical Handover between Wireless Standards
The dynamics of handover between two coexisting wireless standards and the consequent exploitation of the offered diversity by the use of multi-standard terminals has been dis- cussed. The potential capacity benefits of mobile-initiated vertical handovers are substantial.

Cognitive Vertical Handover in Heterogeneous Networks [PDF]
One of the major design issues in heterogeneous wireless networks is the support of seamless vertical handover for mobile users. The cognitive capability for mobile terminal enables the functionalities of system parameter estimation and learning. By utilizing these parameters, cognitive users make a handover decision to select an appropriate point of ...

Vertical handovers as adaptation methods in pervasive systems [PDF]
Pervasive systems need to be context aware and need to adapt to context changes, including network disconnections and changes in network Quality of Service (QoS). Vertical handover (handover between heterogeneous networks) is one of possible adaptation methods.
