On evaluation of a novel method for adaptive management of heterogeneous wireless networks in mobile client-server communication.
Proc. 16th IEEE International Symposium on Personal Indoor and Mobile Radio Communications, Berlin, Germany, 4:2312-2316.
A HTTP input channel can adapt its behavior
according to the changing network status in a context-aware
fashion. The adaptation includes both selecting and dynamically
switching the underlying connection used, as well as coping with
disconnection situation. This paper describes the architecture
and design of HTTP input channel for multi-access wireless
network. A series of experiments were performed in a GPRSWLAN
integrated environment. Performance metrics were
measured and analyzed. In particular, the time delay of channel
creation and connection switching was investigated. For channel
creation, the majority of time delay comes from the normal
operation of HTTP URL connection. More time is needed for
best connection evaluation and default gateway changing when
more than one connection is available. For passive switching
delay both event detection and connection evaluation contribute
to the most besides the normal HTTP connection opening.
