无线传感器网络（WNSs）正逐渐从一个有前途的技术发展成为一个成熟的现实，在一个大的不同的领域。为了满足特定场景的要求，无线传感器网络必须在性能和生命周期之间提供正确的权衡，这在很大程度上取决于网络设计。然而，尽管无线传感器网络的复杂性不断增加，设计空间探索往往是手动进行，没有一个通用的分析方法的支持。在本文中，我们提倡一种基于模型的方法，作为一种有效的和可扩展的方式来探索设计过程中的能源性能权衡。特别是，我们表明，它是可以定义系统级模型来描述广泛的类的无线传感器网络，提供一个快速，准确的网络评估。作为一个概念的证明，我们提出了一个通用的模型，描述了一类无线传感器网络的人类健康监测的主要特点，我们将其应用到一个真实的案例研究。结果表明，与真实的数据相比，该模型的能量性能估计误差从未超过1.74%，而相对于准确的网络模拟，评估时间减少了6个数量级。
Wireless sensor networks (WNSs) are gradually evolving from a promising technology to a well-established reality in a large set of different domains. In order to fulfill the requirements of the specific scenario, a WSN must provide the right tradeoff between performance and lifetime, which is heavily determined by the network design. However, although the complexity of WSNs is increasing, the design space exploration is often carried out manually without the support of a general analytical methodology. In this paper, we advocate a model-based approach as an efficient and scalable way to explore the energy-performance tradeoffs during the design. In particular, we show that it is possible to define systemlevel models to describe wide classes of WSNs, providing a quick and accurate network evaluation. As a proof of concept, we propose a general model that describes the main characteristics of a class of WSNs for human health monitoring, and we apply it to a real case study. The results show that the energy-performance estimation error of the model never exceeds 1.74% compared to real data, while the evaluation time is reduced by up to 6 orders of magnitude with respect to an accurate network simulation.
