Efficient deployment surface area for underwater wireless sensor networks

Abstract

Underwater wireless sensor networks provide a new remote surveillance way to monitor the underwater environment, and have drawn increasing attention in the past few years from both academic and industry. Underwater sensor networks will find applications in oceanographic data collection, ocean sampling, pollution and environmental monitoring, offshore exploration, disaster prevention, assisted navigation, distributed tactical surveillance, mine reconnaissance, and submarine surveillance. Plenty of challenges have to be faced during the research, since the nature of underwater environment variable temporally and spatially. In this paper, the efficient deployment of surface area for underwater wireless sensor networks was presented. To familiarize with underwater wireless sensor networks deployment, this paper started by providing background information on the architecture and trajectory of the sinking node. Then, a kind of novel inflatable sensor nodes was proposed to make sure that they can have a given trajectory, according to the analysis sinking process of the sensor nodes which tie to the anchor with winch. For a given target area, the reducing of surface deployment area and numbers of nodes is the most significant advantage. To illustrate the performance, the compare was made from two aspects.
