A State of Art Concept in Contriving of Underwater Networks
Abstract
The underwater ocean environment is widely considered as one of the most difficult communications channels. Underwater acoustic networks have recently emerged as a new area of research in wireless networking. Underwater networks are generally formed by acoustically connected ocean-bottom sensors, underwater gateways and a surface station, which provides a link to an on-shore control center. In recent years, there has been substantial work on protocol design for these networks with most efforts focusing on MAC and network layer protocols. Low communication bandwidth, large propagation delay, floating node mobility, and high error probability are the challenges of building mobile underwater wireless sensor networks (UWSN) for aquatic applications. Underwater sensor networks (UWSNs) are the enabling technology for wide range of applications like monitoring the strong influences and impact of climate regulation, nutrient production, oil retrieval and transportation, many scientific, environmental, commercial, safety, and military applications. This paper first introduces the concept of UWSN, operation, applications and then reviews some recent developments within this research area and proposes an adaptive push system for dissemination of data in underwater wireless sensor networks. The goal of this paper is to survey the existing network technology and its applicability to underwater acoustic channels. In this paper we provide an overview of recent medium access control, routing, transport, and cross-layer networking protocols. It examines the main approaches and challenges in the design and implementation of underwater wireless sensor networks. Finally, some suggestions and promising solutions are given for these issues.
