  1. 2005 • 5 Engineers : 2 CE, 3 EE • Sponsors : Sensorcon, PCB Express • Advisor : Dr Hu, Dr Reddy Problem : Crossbow Technology provides wireless sensor motes but cost deters the creation of large networks Requirements : Sendingcommands to the network, receiving messages from the connectedmote and display the real time network topology P06501 : About ZigbeeTechnology • Solution : Create low cost ZigBee Data Forwarding Unit (DFU) hardware and software prototype

  2. Why : • Low-power • Low-cost • Use of standard (Protocols and Hardware) • Results : • 3 concepts have been studied, only one until the end • Life-time calculations : more than 4 years • The final project works • Open-Source, Open-Architecture • Lessons Learned : • Find different solutions for the same problem • Low-power implies sleeping devices : how to transmit data to sleeping devices • Most important : separate each part of the project in sub-projects, hence the need of good modularity (interface device/device) P06501 : About ZigbeeTechnology • Conclusion : This project match with our project, the low-power is very useful. The only problem is the range, which is 30ft outdoor. Is it possible to go further with this technology?
