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-执行器网络的最新技术越来越感兴趣。为改善这类网络的架构并利用它们的力量所做的研究工作，是因为它们有潜力为工业流程、交通运输、健康监测、安全和人类安全等重要领域出现的问题提供新一代解决方案。然而，部署特定应用的传感器网络来实现这种建议的解决方案存在缺陷，因为特定应用的网络提供的可扩展性和可重用性有限，因此它们固有地不具有成本效益。通过研究新一代传感器和传感器执行器网络的设计，该研究有助于提供更好的可扩展性和可重用性的解决方案平台，该网络允许在多个应用程序之间以可靠的方式共享资源。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网络基础设施。可以预见，这种架构的可用性将促进和加速由潜在不同的开发商和服务提供商开发的传感器网络解决方案的部署。

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.
