We present TinyWifi, a nesC code base extending TinyOS to support Linux powered network nodes. It enables developers to build arbitrary TinyOS applications and protocols and execute them directly on Linux by compiling for the new TinyWifi platform. Using TinyWifi as a TinyOS platform, we expand the applicability and means of evaluation of wireless protocols originally designed for sensornets to...

The increasing popularity of sensor network has spawned a wide range of platforms and frameworks for sensor network development. While in theory nodes based on different frameworks should provide radio stack compatibility, in practice this is rarely the case. We explore this problem by providing a case study and introduce TinySPOTComm, a customized radio stack for the Sun SPOT platform which al...

The advances in digital circuitry and sensor technology has enabled reliable monitoring of environments through wireless microsensor systems. Event-driven operating system has been shown to meet the requirements of such platforms. In this paper, we focus on TinyOS, an eventbased operating system for Smart Dust networked sensors. We show how to model TinyOS as a hybrid automata with the tool HyT...

As embedded devices become increasingly useful and ubiquitous, it will be important to incorporate them into enterprise applications through Web services and service-oriented architectures. Existing approaches have limitations in terms of either resource consumption or burden on the programmer. In this paper, we present a new framework to automatically export TinyOS modules as Web Services usin...

We present YETI1, an Eclipse plug-in providing support for TinyOS development. YETI provides features wellknown from development environments for other languages such as syntax highlighting, code completion and error detection. Furthermore, it includes an additional set of tools which are designed to ease the TinyOS development process for both newcomers and experienced developers. The plugin s...

We used FPGA for developing prototypes of novel sensor network system because of its short turn-around-time and flexibility. For FPGA-based sensor network system, we have to decrease the size of operating system because of small memory. Scalability is another important feature because if logic circuit in the FPGA is changed, the operating system also has to reflect this modification. In this pa...

Wireless SensorNetworks are aburgeoningareaof researchandapplications in embedded systems. Thepurpose of this project is tounderstandand further developViptos (VisualPtolemyandTinyOS), an integrated graphical development and simulation environment for TinyOS-basedwireless sensor networks. TinyOS is the operating system for the BerkeleyMotes, which are small embedded systems capable of collectin...

Event-driven operating systems such as TinyOS are the preferred choice for wireless sensor networks. Alternative designs following a classical multi-threaded approach are also available. A popular implementation of such a multi-threaded sensor network operating system is MANTIS. The event-based TinyOS is more energy efficient than the multi-threaded MANTIS system. However, MANTIS is more capabl...

TinyOS is a useful resource for developers of sensor networks. The operating system includes ready-made software components that enable rapid generation of complex software architectures. In this paper we describe the lessons gained from programming with the TinyOS communication library. In particular, we try to rationalize existing functionalities, and we present our solutions in the form of a...
