The research domain of UWSN (Under Water Sensor Networks) is gaining wide attention
these days. The sensors are deployed on the sea surface or seabed for monitoring, data collection or
surveillance purpose. Unlike terrestrial networks, the UWSNs use acoustic signals for data communica-
tion. The speed and bandwidth of acoustic signals is low compared to radio signals which are used in
conventional terrestrial WSNs (Wireless Sensor Networks). As a result, protocol design in UWSN must
be addressed separately than terrestrial networks. In this work, we have reviewed TDMA (Time Divi-
sion Multiple Access) protocols for channel access. As TDMA is a collision-free method, it is preferred
over other methods like random access methods or handshaking based medium access protocols. Some
open issues are also proposed as follows: (i) It is found that very less or no work is done in the area of
joint scheduling and topology formation for UWSNs. (ii) The problem of balancing schedule length of
sink-rooted trees in multiple sinks UWSNs is also unattempted.
