Abstract: This paper addresses the problem of enabling mobility in wireless sensor networks. A method for mobile node design is proposed and a prototype node is implemented which is named Racemote. Adding Racemote into the static sensor networks can enhance the functionality of the sensor networks and can help solving many of the research problems of static sensor networks. The hardware platform is built from commercial offtheshell modules, which shows good stability and scalability. The software architecture is based on the embedded operating system TinyOS which simplifies hardware driver design and application programming. The experimental results show that Racemote is capable of planar motion and can be used in the research of wireless sensor and actuator networks or mobile sensor networks.
