A Vertical Handoff Decision Scheme in Heterogeneous Wireless Systems
VTC Spring 2008 - IEEE Vehicular Technology Conference, 2008One of the goals of next generation wireless networks (NGWNs) refers to the ability of supporting heterogeneous wireless access technologies. The objective is to provide a diverse range of seamlessly provide high-data rate multimedia services across different wireless networks. To achieve this, we must rely on seamless vertical handoff techniques.

Providing security vertical handoff in SARAH for heterogeneous networks
Journal of Network and Computer Applications, 2011Vertical handoff is one of the most important issues in the heterogeneous networks. While Lee et al. introduced a selective advance reservations and resource-aware handoff direction (SARAH) mechanism in order to provide a fast and efficient handoff with combination of layer 2 (L2) and layer 3 (L3) communications, there was a drawback that there was no ...

Performance Evaluation of TCP Variants to Downward Vertical Handoff
2006The behavior of a regular TCP is not good to adjust quickly to the new higher available bandwidth of a newly arrived network after a downward vertical handoff In this paper, we compare three TCPs by mathematical and simulation analysis to the downward vertical handoff With mathematical analysis, we compare the link utilization of NewReno TCP, Scalable ...
