Present 3G Mobile Devices are often supports multiple communication technologies. If software developers want to control the configuration or monitor the characteristics of active Radio Access Technologies (RATs), their mobile applications will have to use different programming interfaces for each technology on various supported platform. We propose Modular Data Link Layer M-DALL for a NEXT GEN Mobile...
Roaming across different access technologies permit people to access Internet via heterogeneous wireless networks such as WLAN, WiMAX, GPRS, 3G and Beyond 3G networks. The convergence of heterogeneous wireless access networks with handoff support enable mobile nodes to freely move in and out of any available networks without breaking the connection to the Internet. In this paper, an Adaptive Cross...
With the development of wireless communication technologies and mobile Internet, the demand for the ubiquitous service is increasing dramatically. However, there are many critical issues which prevent the performance in accessing the ubiquitous heterogeneous wireless networks. So the subject has become the focus of many research institutions. We establish a practical testbed which includes the different...
The next generation mobile handhelds need to focus on seamless Mobility and session continuity when the subscribers move frequently across different radio access networks. This paper presents a generic radio access abstraction layer (GRAAL) outlining the additional functionalities required at the mobile terminal that can decide on the fly for selecting the best radio access network according to the...
