Wireless sensor networks have found a wide range of applications – from environmental monitoring to automation systems. Developing applications using wireless sensor platforms involves intensive experimentation and testing. Building the experimental system with actual physical components like sensors may not be practical due to high cost or unavailability of the sensors. This problem can be solved by implementing virtual sensors that mimic the real sensors but which are implemented in software. The virtual sensors are abstractions of the physical sensors. They mimic the real sensors in all their functionality but is available at a fraction of the cost. In this thesis we describe Emuli — a method of effectively substituting sensor data by synthetic data on physical wireless nodes (motes). The sensor application is oblivious to this substitution. Emuli generates data on demand from the application. The replies are based on the sensor model which is driven by the data preloaded to the mote before the experiment. Since the preloaded data is an approximation of the sensor behavior rather than raw sensor readings, it is rather compact. Therefore it can be stored in the memory of each individual device. The emulated stimuli can be synchronized and coordinated across multiple motes which allows to experiment with distributed events. Emuli abstracts the sensing component of a complete application and allows the experimenter to focus only on processing and transport function of a wireless sensor networks. We demonstrate statistical and deterministic sensor models. We showcase the use of Emuli in a light measurement and industrial automation system implementation.
