Underwater acoustic networks deals with a network of sensors placed to monitor different parameters in the underwater environment. Acoustic medium is selected for data transmission from the underwater bed to the onshore station, and also between two nodes due to their suitability over radio or optical medium. Applications of underwater sensor network include monitoring of the ocean, navigation and surveillance applications. The dynamic underwater environment makes it difficult for the sensors to record and transmit data. Different architectures available for underwater sensor networks have been discussed. Challenges in routing information in underwater environment have been discussed. In this article, emphasis has been laid on some of the existing routing protocols and are being compared basing on different parameters.
