The Virtual Node Layer: A Programming Abstraction for Wireless Sensor Networks
Overview The Virtual Node Layer (VNLayer) programming abstraction provides programmable, predictable automata-virtual nodes-emulated by the low-level network nodes. This simplifies the design and rigorous analysis of applications for the wireless sensor network setting, as the layer can mask much of the uncertainty of the underlying components. This paper defines a general VNLayer architecture, and then uses this framework to design a practical VNLayer implementation, optimized for real-world use. The paper then discusses the experience deploying this implementation on a testbed of hand-held computers, and in a custom-built packet-level simulator, and present a sample application-a virtual traffic light-to highlight the power and utility of the abstraction. The paper concludes with a survey of additional applications that are well-suited to this setting.
