UNDERWATER BASED ADHOC NETWORKS: A brief survey to its challenges, feasibility and issues

Wireless mobile Adhoc network has been widely used in a variety of practical applications. The major advantage of using these networks is that it does not rely on existing infrastructure for communicating between its nodes. Generally, these networks on the basis of deployment scenario of nodes are classified as MANET, VANET, and FANET. However, a similar concept of these wireless ad-hoc mobile networks can also be applied in underwater based applications, where a group of mobile nodes, submerged in water, forming a wireless ad-hoc network, are deployed to coordinate and communicate themselves, to carry out useful tasks. A major portion of the sea is unexplored till today and these networks could be of high advantage and have huge potential in surveillance, monitoring, military, geological activity, marine life monitoring, and many others. However, less work has been done in this area. The objective of the paper is to highlights the advantages, issues, challenges, in building such a realistic system. Moreover different applications scenario, future perspective has been proposed where these networks would be highly useful.
