In this article, based on the overview of network coupling structure between radio access technologies, the concept of joint radio resource management built onto the reference structure is introduced. In order to optimize usage of radio resource and jointly designed from the user perspective, a joint scheduling mechanism allowing traffic to be split over a tightly coupled radio network supported by an adaptive radio multihoming approach is deliberately discussed. With respect to the time-division access scheme in HIPERLAN/2, which is selected as one example of WLAN, algorithms and performance of traffic scheduling in such a radio access technology are given. The required synchronization scheme supporting traffic splitting is also introduced.read more

Mobility model for heterogeneous wireless networks and its application in common radio resource management
Abdul Hasib,Abraham O. Fapojuwo +1 more
TL;DR: Numerical results show that the mobility-based CRRM scheme exhibits a lower rate of unnecessary vertical handoffs than that achieved by the dasiaWLAN' if coveragedasia scheme that does not use mobility information for resource management.

Multi layer rules based framework for vertical handoff
A. Sur,Douglas Sicker +1 more
TL;DR: A novel framework that executes vertical handoff based on a multilayer approach coupled together with adjunct information such as pricing and user preference is developed, which allows changes in applications, variations in network conditions and user preferences to trigger vertical handoffs.
