Self-Tuned Remote Execution for Pervasive Computing
Pervasive computing creates environments saturated with computing and
communication capability, yet gracefully integrated with human users.
Remote execution has a natural role to play in such environments,
since it lets applications simultaneously leverage the mobility of
small devices and the greater resources of large devices. In this
talk, I will describe Spectra, a remote execution system designed for
Spectra monitors resources such as battery energy and file cache state
which are especially important for mobile clients. It also
dynamically balances energy use and quality goals with traditional
performance concerns to decide where to locate functionality.
Finally, Spectra is self-tuning -- it does not require applications to
explicitly specify intended resource usage. Instead, it monitors
application behavior, learns functions predicting their resource
usage, and uses the information to anticipate future behavior.

Carnegie Mellon University. His research focuses on prolonging the battery
lifetimes of mobile computers.
