Dependable services on wireless sensor networks

近年来，世界范围内对无线传感器网络和无线传感器-执行器网络的设计越来越感兴趣。改进此类网络架构和利用其力量的研究工作的动机是，它们具有为工业过程、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的潜力。然而，部署特定于应用程序的传感器网络来实现这些提出的解决方案存在缺点，因为特定于应用程序的网络提供有限的可扩展性和可重用性，因此它们本质上不具有成本效益。该研究通过研究新一代传感器和传感器执行器网络的设计，有助于提供更好的可扩展和可重用的解决方案平台，该网络允许以可靠的方式在多个应用程序之间共享资源。因此，新一代面向服务的网络需要具有灵活性、可配置性和可扩展性，以便提供独立于应用程序的可分配网络基础设施。预计这种架构的可用性将促进和加速传感器网络解决方案的部署，这些解决方案可能由不同的开发人员和服务提供商开发。

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.
