Information dissemination in Underwater Wireless Acoustic Sensor Networks

Abstract

Oceans constitute a huge portion of the Earth s surface, and there are many underwater applications, newlinenevertheless our understanding of these applications is insufficient. Due to their broad newlineapplications in a variety of underwater scenarios, there seems to be an increasingly great deal newlineof research on underwater wireless acoustic sensor networks (UWASNs) in recent years. Since newlineradio waves are quickly captured and diminished in underwater, the UWASNs utilize acoustic newlinewaves for underwater environment. UWASNs are a framework that can be used in a variety of newlinescience, commercial, and military circumstances. Environmental monitoring, scientific discovery, newlinedisaster mitigation, aided navigation, coastal surveillance and protection for military purposes, newlineweather prediction, oceanographic data collection, mine detection, and other underwater newlineapplications are all possible with these UWASNs. UWASNs are made up of a range of heterogeneous newlinenodes such as underwater sensor nodes, autonomous underwater vehicles (AUVs), newlineremotely operated vehicles (ROVs), Under-Water Gateways (UW-GW), several surface gateways, newlinedivers, and submarines that interact with one another to carry out particular activities. In newlineprocess of adapting to the ocean world, sensors and AUVs self-organize and form autonomous newlinenetworks to accomplish a desired goal. The UWASN architecture is divided into two categories: newlinetwo-dimensional (2D) and three-dimensional (3D). newlineThe applications are mostly concerned with exchanging data in a sequential manner, which is newlineknown as information dissemination. In general, a sensor network is thought to consist of a vast newlinenumber of sensor nodes that must connect with one another. Despite the fact that a centralized newlinecontroller provides a specific route between the source and destination nodes, mobility, high newlinepath loss, limited latency, excessive energy consumption and network failures all result in certain newlineconnection gaps. As a consequence, it has an effect on data transfer from the source to the newlinedestination. Data retransmission requires ti
