A Study on Wireless Sensor Network Development Support

在这个项目中，我们已经开发了方法和环境，以支持无线传感器网络应用程序和系统的开发。在这种方法中，我们提供了（i）有用的抽象模型，独立于特定的语言和体系结构，（ii）一个自动推导算法，以隐藏低层次的原语中使用的程序代码的传感器节点从开发人员，和（iii）性能验证系统，便于模拟和执行开发的WSN系统。合作的无线传感器网络的应用程序，这是已知的是相当困难的，由于通信和事件处理原语的复杂的相互作用的发展，我们已经证明了这样的应用程序的整个开发过程，并确认我们的支持功能，如算法级设计，自动推导低级别的代码，和模拟和真实的环境之间的无缝评估的好处。我们已经开发了位置估计和管理系统，以验证所提出的方法和环境。

In this project, we have developed methodology and environment to support development of wireless sensor network applications and systems. In this method, we have provided(i) useful abstraction models that are designed independently of specific languages and architecture,(ii) an automated derivation algorithm to hide low-level primitives used in program codes of sensor nodes from developers, and(iii) performance verification systems that facilitate simulations and execution of developed WSN systems. Focusing on development of cooperative WSN applications which is known to be quite hard due to complex interactions of communication and event process primitives, we have testified the whole development process of such an application, and confirmed the benefit from our support functions such as algorithm level design, automated derivation of low level codes, and seamless evaluation between simulation and real environment. We have developed location estimation and management system to validate the proposed methodology and environment.
