Opportunistic Void Avoidance Routing (OVAR)
protocol has been proposed for Under Water Sensor
Network (UWSNs). OVAR is a multicast, geographic and
opportunistic routing protocol that passes information
packets from sensor nodes to various sonobuoys (sinks) at
the ocean's surface. OVAR protocol switches to recovery
mode which depends on the depth conformity of the void
nodes. A protocol ways to deal with keep up directing along
void region by the utilizing control messages. Under Water
Remote Sensor Network appeared as an encouraging
innovation to investigate customary undersea wire line
instruments. One approach to enhance the information
accumulation and the network execution in UWSNs is
through considering the qualities of the underwater acoustic
correspondence. The OVAR profoundly used in dynamic
network topology, even in hard and troublesome mobile
situations of extremely inadequate and thick networks. By
using the OVAR routing protocol for the speed of the node
will increased as well it prevents data loss compared to
previous method.

From this literature survey, it is found that the techniques
supporting multiple tables are not very efficient. OVAR
protocol is proposed to improve the data routing in Under
Water Sensor Networks. OVAR is a simple and scalable
geographic routing protocol that uses the position
information of the nodes and takes advantage of the
broadcast communication medium to greedily and
opportunistically forward data packets towards the sea
surface sonobuoys. Furthermore, OVAR provides a novel
depth adjustment based topology control mechanism to
move void nodes to new depths for overcoming the
communication void regions. Simulation results shows
that opportunistic routing protocols based on the position
location of the nodes are more efficient than other routing
protocols. Moreover, Opportunistic routing proved crucial
for the performance of the network besides the number of
transmissions required to deliver the packet. The use of
node depth adjustment to manage with communication
void regions improves significantly with network
performance.
