ABSTRACT
We consider the problem of maximizing the time-to-first-
failure (TTFF), defined as the time till the first node in the
network runs out of battery energy, in energy constrained
broadcast wireless networks. We show that the TTFF cri-
terion, by itself, fails to provide the "ideally optimum" mul-
