Deployment algorithms in Underwater Acoustic Wireless Sensor Networks: A Review

Deployment of sensors in the underwater acoustic sensor network is a very challenging task due to the complex 3d environment in underwater sensor networks because acoustic signal is affected by salinity, temperature, and pressure. The main objective of deployment algorithm is to achieve maximum coverage with a minimum number of underwater acoustic sensor nodes or surface gateways in underwater acoustic sensor networks. A network with complex deployment increases the complexity of the other operation on the network such as routing protocol, localization etc. in this paper we study the various deployment algorithms. According to the mobility of the nodes to be deployed in the network, classification of the algorithms is static nodedeployment, self-adjusting nodedeployment, and movement aware node deployment.
