... tutorial originated in the Embedded Systems lecture, a graduate course taught at the Department of Information Technology and Electrical Engineering, ETH Zurich. It requires basic knowledge of C- programming and embedded systems and should give an overview of the capabilities of networked embedded systems and their key properties. Apart from usage in the lecture it is a basic introduction to programming on the BTnode platform. To be able to do the practical exercises in this tutorial you will need a BTnode developer kit (see Figure 1.2) consisting of a BTnode rev3, a usbprog USB programming adapter, an Atmel ATAVRISP programmer, a serial and a USB cable, a 15-Pin Molex breakout cable and the software, documentation and tools contained on the BTnode. For a complete listing of tools and versions used in this tutorial please see appendix ...

Conference Paper
A Wireless sensor network (WSN) consists of a potentially large number of sensor nodes with wireless-communication capabilities that work collaboratively to achieve a common goal. While every WSN application has specific requirements, there are some common basic services that any WSN must offer in order to support applications. There are available commercial WSN nodes offering such basic services, but they are still very expensive. So, we ask ourselves if it is possible to build a WSN node keeping low costs, while at the same time implementing these basic services: the answer is yes. We built sensor nodes and we call them WiSe-Nodes. In this paper we present the architecture of our WiSe-Nodes as well as the details about their hardware modules. We present also an hybrid MAC-routing protocol called WASP that implements the basic services of a WSN. Finally, as a tool for the WSN developers we introduce our simulator YAWSS that provides a controlled test environment where new WSN protocols can be tested and executed before implementing them in hardware.
