We consider the problem of jointly maximizing the time-to-
first-failure (TTFF), defined as the time till the first node in
the network runs out of battery energy, and minimizing the
total power in energy constrained static wireless networks.
It is shown in  that simply optimizing the TTFF criterion
may not provide the ideally optimum solution. Besides max-
imizing the TTFF, the ideally optimum solution guarantees
that the lifetimes of all nodes are at least as high as in other
