ABSTRACT
As wireless communications services continue increasing,
continuous coverage and QoS parameters must be
guaranteed to the end user. Due to the fact that in most
places several wireless networks might be available, handing
off between them can significantly enhance network
efficiency and user satisfaction. In such a scenario,
continuous environment monitoring is required for
estimating links' conditions in real time from which the
network selection process is executed. This paper presents a
vertical handoff architecture relying on SDR capable devices
for simultaneous diverse networks' parameters identification
and dynamic communication link adaptation.
