All routing perform each and specific task into underwater sensor network which responsible for networking problems issue that is why this is the latest way of research. Routing term derived from “route” that means a path a way that perform different terms in underwater sensor network problem related issue. The best part is today many routing protocol are present in the underwater wireless sensor network. Some different attributes comes underwater wireless sensor network like likes high bit error rates, limited band-width, 3D deployment and high propagation delay. This paper is referring to as helpful for giving brief overview about each and every protocol and responsible for entire underwater wireless sensor network. Keyword: Underwater sensor network, routing protocol I. INTRODUCTION In our earth 25% covered by human being and remaining space is covered by water that could be river and oceans also. In underwater wireless sensor network much small water living thing like fish, crocodile and many more. Suppose a scientist work on particular a particular thing so some special devices should be in underwater wireless sensor network that can work in underwater wireless sensor network system which should be able to interact within underwater. Today increasing the demand some special routing protocol which can work into underwater wireless sensor network. For the current point of research scenario underwater sensor network with some different routing protocol available that play some specific role in the underwater wireless sensor network that why some scientists are working Abdul .
