| Abstract | The rapidly increasing data usage and overload in mobile
broadband networks has driven mobile network providers to
actively detect and bill customers who tether tablets and
laptops to their mobile phone for mobile Internet access.
However, users may not be willing to pay additional fees only
because they use their bandwidth differently, and may con-
sider tethering detection as violation of their privacy. Fur-
thermore, accurate tethering detection is becoming harder
for providers as many modern smartphones are under full
control of the user, running customized, complex software
and applications similar to desktop systems.
In this work, we analyze the network characteristics avail-
able to network providers to detect tethering customers. We
present and categorize possible detection mechanisms and
derive cost factors based on how well the approach scales
with large customer bases. For those characteristics that
appear most reasonable and practical to deploy by large
providers, we present elimination or obfuscation mechanisms
and substantiate our design with a prototype Android App. |
