A distributed scheme for 3D space coverage in tactical underwater sensor networks

In this paper, a distributed scheme for three dimensional sensor space coverage in tactical underwater sensor networks is introduced. When sensor nodes are first deployed, sensors lie in surface buoys. After deployment, sensors are lowered to various depths selected by our scheme such that the maximum coverage of the three dimensional sensor space is maintained. Experiments show that our scheme maintains more than 90% coverage efficiency most of the time at the expense of acceptable control traffic overhead.
