This paper uses the open-code TinyOS system and MoteIV Tmote Sky which support the system to development platforms. Tmote Sky nodes distributed over every corners, use TinyOS MAC layer protocol to write down the single hop and multi-hop data stack programs, and though Matlab access with TinyOS to display the every nodes on-time RSSI. It is provide the basic of RSSI to estimate distance in WSN by the paper. Keywords Wireless sensor Network (WSN), TinyOS, Tmote Sky. 1.
