3G networks and Wi-Fi networks could complement
each other as each has different advantages of coverage and
access capacity. A combined 3G and Wi-Fi network is one part of a
heterogeneous IP network which has ubiquitous access capacity.
However, the characteristics of the lower layers in the wireless
network portion of such a heterogeneous IP network could
significantly affect the performance of higher layers, and further,
the overall performance of the whole network. A single-layer
approach to performance analysis could not provide enough
information to present the correlation between lower and higher
layers. A cross-layer measurement approach for combined 3G and
Wi-Fi network is presented which aims to correlate the
characteristics of the physical layer (e.g. channel power and
signal-to-interference ratio) to key parameters of higher layer (e.g.
packet-loss ratio, and round trip time).
