The ZRL Wireless Sensor Networking Testbed

This paper describes the ZRL wireless sensor networking testbed built within the framework of the Zurich "Sensor Networks" and "Edge Server Software" projects. Besides its function as a demo platform for customer engagements, the testbed is used to address a wealth of exciting research challenges. We are carrying out performance evaluation with short-range wireless technologies that are highly relevant for sensor networking, such as IEEE 802.15.4 / ZigBee, Bluetooth, and IEEE 802.11. We explore the merits of wireless mesh networking to extend the range and enhance reliability. Also we are developing new light-weight messaging protocols which allow to bring messaging oriented middleware down to very low-end sensors or actuators enabling a true end-to-end solution. In addition, we address the growing need for location-sensing functionality in wireless and sensor networks.
