Error Control and Reliable Data Delivery in UWSNs

Abstract

Underwater wireless sensor networks (UWSNs) contains many components such as vehicles and sensors that are deployed for cooperative monitoring and data collection tasks in a particular acoustic environment various nodes and ground-based stations use these networks interactively. Presently, UWSNs face the problems and obstacles regarding limited bandwidth, high propagation delay, 3D topology, media access control, routing, resource utilization, and power constraints. The research community has developed different methodologies over the past few decades to address these issues and challenges; but, due to complex characteristics of the underwater environment, some of them are still open to research. The main drawback of the traditional approach is the lack of direct interaction between different ends, recorded information can never be accessed during any mission, and data recorded will be lost in the event of any failure.
