The ability to overhear and analyse packets is essential for the development of protocols for IEEE 802.15.4-based Wireless Sensor Networks. Besides a number of commercial hardware and software offers, only very few projects put effort in developing such solutions. This demonstration shows a simple yet powerful approach to that problem. By using a T-Mote Sky sensor node with the Contiki operating system, radio packets can be overheard and then analysed in Wireshark on an attached Linux PC. By creating custom dissector components for Wireshark, new protocols can easily be analysed and problems in the network can be debugged.
