AbstractTraditionally, multimedia applications have been primarily constrained by a lack of bandwidth. In mobile systems, however, energy constraints must be considered as well. While these constraints are related, they differ in one key way: bandwidth is renewable, but energy is not. This implies that techniques for managing bandwidth, typically performed at the transport layer, must be reconsidered in terms of their energy efficiency as well. Traditionally, these transport layers are evaluated in terms of application good-put, or the amount of useful data received by the application. We propose that they should also be evaluated in terms of the total amount of data sent per useful data unit received at the application, which we term data expansion.
