Proposed in this paper is a relative complexity metric deduced from the principles of cross-entropy associated with a complex system. Further indicated is the use of such a metric in decision-theoretic applications relevant to a complex system. As an example, the proposed method is applied to modern cellular phone systems in facilitating the so-called hard handoff effort by which, a mobile unit switches to a new base station when the signal from the serving base station becomes too weak (as a result of inevitably prevailing fading conditions). This wireless communication based decision-making scenario is justifiably portrayed as a spatiotemporal exercise in a complex system. The efficacy of the proposed relative complexity metric in facilitating the handoff effort is illustrated via simulations and discussed.
