不断增长的航空运输量要求航空业采用新技术，以满足安全、安保、经济实惠和环境友好的要求，同时满足不断增长的需求。为了实现这一目标，我们需要一种新型的飞机巡航控制系统，将所有机载主动控制系统互连起来，做出比目前更准确的控制决策，从而提高整体飞行效率。Active Aircraft设想了这样一个由分布式无线传感器和执行器网络组件组成的神经系统，能够及早发现潜在问题，并对这些问题做出快速、准确的反应。作为这一愿景的一部分，部署在飞机机翼上的wsan有助于减少气动阻力，并显著降低燃油消耗。在本文中，我们首先描述了飞机控制技术的这种概念变化。然后，我们引入一个WSAN应用程序来减少表面摩擦阻力，并引入一个网络拓扑来启用它。在我们的应用中，WSANs在机翼上形成虚拟襟翼阵列，实时测量表面摩擦，并使用合成射流致动器进行反应，该致动器吸入和排出机翼上的空气以减少摩擦。主动飞机视觉对底层WSAN通信算法提出了严格的性能要求。特别是媒体访问控制和路由协议，必须满足主动控制应用程序设置的服务质量标准。因此，我们也提出了主动飞行器的应用特点，并提出了有关通信协议的设计考虑问题。
The ever increasing volume of air transport necessitates new technologies to be adopted by the flight industry to fulfill the requirements of safety, security, affordability, and environmental friendliness while still meeting the growing demand. What we need to achieve this goal is a new type of aircraft cruise control, interconnecting all the onboard active control systems and making more accurate control decisions than is currently possible, thus improving overall flight efficiency. Active Aircraft envisions such a nervous system of distributed wireless sensor and actuator network components, enabling the early detection of potential problems and quick, accurate reactions to these. As part of this vision, WSANs deployed on aircraft wings help reduce aerodynamic drag and significantly reduce fuel consumption. In this article we first describe this conceptual change in aircraft control technology. We then introduce a WSAN application to reduce skin friction drag and a network topology to enable it. In our application WSANs form virtual flap arrays on the wings to measure the skin friction in real time and to react using synthetic jet actuators, which suck and expel air on the wing to reduce the friction. The Active Aircraft vision imposes stringent performance requirements on the underlying WSAN communication algorithms. The medium access control and routing protocols, in particular, must meet the quality of service criteria set by active control applications. Thus, we also present the application characteristics of Active Aircraft and raise the issue of design considerations with regard to the communication protocols.
