Abstract

In order to achieve seamless interoperability in
heterogeneous networking, it is vital to improve the
context-awareness of the mobile node (MN) so that it is
able to predict future network conditions with sufficient
accuracy. In this paper, we introduce a predictive
mathematical model for calculating the estimated Time
Before Vertical Handover (TBVH) component from
available network parameters. The model is practically
implemented in OPNET and our simulation results
confirm the validity of the concept. We then demonstrate
how the knowledge of TBVH along with other network
parameters can be applied by downward Quality of
Service management policies which bundle multi-class
traffic streams on to available network channels based
on application QoS, device mobility patterns and
prevailing channel conditions.
