水下传感器网络代表了一个重要的和有前途的研究领域，因为这些网络可以支持水下无处不在的应用的巨大多样性，例如，提供海啸和石油泄漏警报或监测海底生态系统的系统。这些监测和报警系统中的大多数需要在具有低节点密度的广域网中进行实时通信。这些网络所涉及的水下通信介质非常苛刻，对通信过程施加了很强的限制。在这种情况下，信息的实时传输主要使用声学信号来完成，因为网络节点在物理上并不靠近。通信场景的特征和通信过程的要求对通信协议以及监控和警告系统的设计者来说都是重大挑战。缺乏模型来表示这些网络是水下无处不在的系统扩散的主要绊脚石。针对水声传感器网络中节点密度低、覆盖范围广的特点，提出了一种基于任意对任意通信的水声传感器网络实时通信模型。该模型是解析的，考虑了两种解决方案的调度实时消息，并提供了一个时间约束分析的网络性能。使用这个模型，协议和水下无处不在的系统的设计者可以快速原型和评估他们的解决方案，在一个不断发展的方式，以确定最佳的解决方案正在解决的问题。该建议的适用性说明了一个案例研究，显示了在几个初始条件下的UW的性能。这是第一个分析模型，代表在这种类型的网络中的实时通信，因此，它打开了大门，水下无处不在的系统的几个应用场景的发展。
Underwater sensor networks represent an important and promising field of research due to the large diversity of underwater ubiquitous applications that can be supported by these networks, e.g., systems that deliver tsunami and oil spill warnings, or monitor submarine ecosystems. Most of these monitoring and warning systems require real-time communication in wide area networks that have a low density of nodes. The underwater communication medium involved in these networks is very harsh and imposes strong restrictions to the communication process. In this scenario, the real-time transmission of information is done mainly using acoustic signals, since the network nodes are not physically close. The features of the communication scenario and the requirements of the communication process represent major challenges for designers of both, communication protocols and monitoring and warning systems. The lack of models to represent these networks is the main stumbling block for the proliferation of underwater ubiquitous systems. This paper presents a real-time communication model for underwater acoustic sensor networks (UW-ASN) that are designed to cover wide areas with a low density of nodes, using any-to-any communication. This model is analytic, considers two solution approaches for scheduling the real-time messages, and provides a time-constraint analysis for the network performance. Using this model, the designers of protocols and underwater ubiquitous systems can quickly prototype and evaluate their solutions in an evolving way, in order to determine the best solution to the problem being addressed. The suitability of the proposal is illustrated with a case study that shows the performance of a UW-ASN under several initial conditions. This is the first analytic model for representing real-time communication in this type of network, and therefore, it opens the door for the development of underwater ubiquitous systems for several application scenarios.
