Improving a Utility Function for Wireless Data
Abstract
We propose a significant improvement to a quality-of-service index on which
several recently published scholarly works have been based. They use this
index as a "utility function" in a formulation of radio resource management
issues, in particular power control, from the perspective and explicitly
using the language of microeconomics theory. The literature's index is based
on an ad-hoc, difficult to interpret transformation of a physically-signifiant,
intuitively appealing but technically misbehaving ratio. Our index is physically
significant, and intuitively appealing, without the technical misbehavior
which made the original ratio undesirable.
