In heterogeneous Wireless communication network, transferring of data between moving
nodes can be handled by well designed mobility management system, in which handover is …

Acquiring seamless handover in IP multimedia subsystem (IMS)-based heterogeneous
internetworking environment still remains an unsolved issue. It is highly difficult to achieve …

Vertical handoff enables the cross-domain mobility in wireless networks. Algorithms are
crucial to achieve an optimal handoff management in terms of performance and quality of …

As the number of mobiles and mobile networks increases every year, we are facing new
problems and challenges in incorporate various networks with various standards and …

To implement seamless mobility inside an integrated, multiple (eg GPRS/WiFi) access
system, a vertical handover policy has to be devised. This is usually done at the mobile …

The integration of heterogeneous access networks into a ubiquitous wireless environment
has commenced. However, in contrast with homogeneous networks (eg, GPRS or UMTS) …

Revolutionary drivers for 4G include a push toward universal wireless access and
ubiquitous computing through seamless personal and terminal mobility. One of the major …

Mobile devices with two network interfaces (WiFi and 3G) are already commercially
available. Point-to-point communications such as Infrared and Bluetooth are also readily …

In this paper, we analyze the performance of vertical handover (VHO) algorithms for
seamless mobility between WiFi and UMTS networks. We focus on a no-coupling scenario …

Beyond 3G wireless networks must be able to coordinate services within a diverse network
environment. One of the most challenging problems for coordination is vertical handover …
