Dependable services on wireless sensor networks

近年来，世界范围内对设计无线传感器网络和无线传感器-致动器网络的最新技术的兴趣越来越大。改进这种网络的架构并利用其力量的研究工作是由其提供新一代解决方案的潜力所推动的，这些解决方案可以解决工业过程，运输，健康监测，安全和人类安全等重要领域中出现的问题。然而，部署专用传感器网络来实现这样的所提出的解决方案具有缺点，因为专用网络提供有限的可扩展性和可重用性，并且因此它们本质上不具有成本效益。拟议的研究有助于提供更好的可扩展和可重用的解决方案平台，通过调查设计的新一代传感器，传感器执行器，网络，允许多个应用程序之间的资源共享在一个可靠的方式。 因此，这种新一代面向服务的网络需要是灵活的、可配置的和可扩展的，以便提供与应用无关的可重任务的联网基础设施。据设想，这种架构的可用性将促进和加速部署传感器网络解决方案开发的潜在不同的开发商和服务提供商。

In recent years, there has been a growing interest worldwide in advancing the state of the art in designing wireless sensor networks and wireless sensor-actuator networks. Research efforts on improving the architecture of such networks and harnessing their power are motivated by their potential in providing a new generation of solutions to problems that arise in vital domains such as industrial processes, transportation, health monitoring, security, and human safety. The deployment of application-specific sensor networks to realize such proposed solutions, however, suffers from drawbacks as application-specific networks offer limited extensibility and reusability, and hence they are inherently not cost-effective. The proposed research contributes to providing better extensible and reusable solution platforms by investigating the design of a new generation of sensor, and sensor-actuator, networks that allows sharing of resources among multiple applications in a dependable way. As such, this new generation of service oriented networks are required to be flexible, configurable, and extensible so as to provide application-independent retaskable networking infrastructure. It is envisioned that the availability of such architectures will facilitate and accelerate the deployment of sensor network solutions developed by potentially different developers and service providers.
