Abstract--- Delay tolerant networks (DTNs) are mobile wireless
networks that are characterized by frequent partitions and
potentially long message delivery delays. Such networks have the
potential for use in important application environments where en­
ergy sources are limited. Therefore, efficient power management
mechanisms are necessary to allow these networks to operate over
a long period of time. In this paper, we leverage the observation
that many DTNs are characterized by sparse connectivity, pro­
viding the opportunity to save energy by aggressively disabling
node radios (sleeping). The major challenge is to balance sleeping
periods with wake­up periods so that valuable and infrequent
