Xaohui, The problem of noise in received signal strength readings is not limited to TinyOS. To the best of my knowledge, the majority of the literature on RSSI values has concluded that it's inherently very noisy (http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=5937980). If you have a solution to cope with the interference, I'm sure you'd get a good research paper out of it alone. Best of luck,
