<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">The University of Pisa and IIT, an Institute of the Italian National Research Council, have designed and developed a crowdsourcing-based system, named PORTOLAN, which initially employed smartphones as mobile monitors probing the Internet. The aim of PORTOLAN is to enhance the current topology of the Internet at the Autonomous System level of abstraction - all with the contribution of volunteers.

<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">PORTOLAN works in the background, it is designed not to interfere in any way with users' activities and does not affect the smartphone</FONT></SPAN><SPAN LANG="it"></SPAN><SPAN LANG="en-us"><FONT FACE="Calibri">/desktop</FONT></SPAN><SPAN LANG="it"></SPAN><SPAN LANG="en-us"><FONT FACE="Calibri">’s overall performance. In order to motivate users to contribute to the PORTOLAN project, we have added several services, which include diagnostic network tools (such as Ping, Paris Traceroute with Multipath Detection Algorithm, Maximum Throughput achievable along a path, etc.) and coverage measurement tools</FONT></SPAN><SPAN LANG="it"></SPAN><SPAN LANG="en-us"><FONT FACE="Calibri"> (available on smartphones only)</FONT></SPAN><SPAN LANG="it"></SPAN><SPAN LANG="en-us"><FONT FACE="Calibri">. All the tools are totally under the user's control.
