The large base of Internet-enabled smartphones
provides an excellent opportunity for a fine-grained observation
of the structure of the Internet and a quantitative evaluation
of its characteristics. Smartphones can operate as active mobile
monitors and, coordinated by a central entity, they can probe
the network on a local scale. Then the results produced by a
large number of participants can be merged to obtain a detailed
graph of the Internet. Besides the design of the measurement
framework, this thesis describes the implementation and validation
of a traceroute-like tool that is compatible with the Android
platform. This confirms that smartphone-based crowdsourcing of
network properties can be a viable strategy.
