ABSTRACT
Existing on-demand ad-hoc routing algorithms initiate route dis-
covery only after a path breaks, incurring a significant cost in de-
tecting the disconnection and establishing a new route. In this
work, we investigate adding proactive route selection and main-
tenance to on-demand ad-hoc routing algorithms. More specifi-
cally, when a path is likely to be broken, a warning is sent to the
source indicating the likelihood of a disconnection. The source can
