Abstract
CarTel is a mobile sensor computing system designed to
collect, process, deliver, and visualize data from sensors lo-
cated on mobile units such as automobiles. A CarTel node
is a mobile embedded computer coupled to a set of sensors.
Each node gathers and processes sensor readings locally be-
fore delivering them to a central portal, where the data is
stored in a database for further analysis and visualization. In
the automotive context, a variety of on-board and external
sensors collect data as users drive.
CarTel provides a simple query-oriented programming in-
terface, handles large amounts of heterogeneous data from
sensors, and handles intermittent and variable network con-
nectivity. CarTel nodes rely primarily on opportunistic wire-
less (e.g., Wi-Fi, Bluetooth) connectivity--to the Internet,
