	abstract = {Reliable data delivery for underwater acoustic sensor
networks is a major concern in applications such as surveillance,
data collection, navigation, and ocean monitoring. Geocasting {\textendash}
which is the transmission of data packet(s) to nodes located in a
certain geographic region {\textendash} is becoming a crucial communication
primitive. In this work, two versions of a distributed, reliable,
and efficient underwater geocasting protocol, which are based
on different degrees of neighbor information, are proposed for
underwater networks whose acoustic modems use random-access
Medium Access Control (MAC) protocols. By jointly considering
the position uncertainty of nodes, MAC, and routing functionalities,
packet transmissions are prioritized and scheduled in order
to maximize link reliability while limiting end-to-end geocasting
delay. Moreover, a mechanism is designed to save the number of
transmissions by selecting only a subset of neighbors for packet
forwarding. Performance of the proposed protocol is evaluated
and compared via simulations against existing geocasting solutions
tailored for terrestrial wireless networks.},
