+ abstract = {With the widespread availability of multiple wireless network technologies, mobile com-
+puting devices can benefit from almost uninterrupted connectivity by changing network
+attachments as they move. This however raises the problem of the selection method to be
+used for the choice of the wireless networks to associate with, in order to provide the best
+performance. Moreover, mobility events may result in poor application quality, due to
+either a disruption in connectivity during the handover or the heterogeneity of the charac-
+teristic of different access networks. To address these problems, this thesis introduces and
+studies all three elements (observation, decision, action) of a control framework to enable
+better use of available network resources.
+We first show that a decision mechanism which directly considers the relevant user- and
+application-centric metrics is more appropriate than using the common network metrics-
+based indirect approach. This mechanism is used to control the entire network stack
+of the mobile node in a coordinated way, rather than individual components, to avoid
+potentially conflicting combinations. Our results indicate that, by exploiting the flexibility
+of application parameters, it is possible to maintain high application quality while reducing
+both the power consumption and access price.
+We then introduce a mobility-aware extension to the {TCP}-Friendly Rate Control mechan-
+ism ({TFRC}), as an action element, to address the disruption in connectivity resulting from
+the mobility events. We propose to suspend the transmission before disconnections and to
+probe the network after reconnections. Simulations demonstrate how this enables faster
+recovery after disconnected periods as well as a significantly improved adaptation to the
+newly available network conditions. When used with the Datagram Congestion Control
+Protocol ({DCCP}), experiments show that it provides better support for real-time applica-
+tions for which the user-perceived quality is very dependent on the immediate transmission
+rate.
+Finally, we present an experimental process to evaluate the {OMF} Measurement Library
+({OML}), a lightweight instrumentation and reporting tool which we propose to use as the
+observation element of our framework. We show that this library does not significantly
+impact the performance of the instrumented applications, while accurately reporting the
+observed metrics.},
