Sometimes when I send RPC commands to sensor network to adjust sampling
rate, the sink die . I need to disconnect power to restart it again. What I
use is Tinyos-1.x and Imote2 platform.
Moreover, when I implemented a reliable data transport module, this also
happended. It works as following: sensor nodes send packets to PC, and then
PC sends back acknowledgement if packets are received. After my program run
for a period, the sink die. Even if I simplify the program(sensor node sends
a packet to PC and then wait for another period to send packets again; For
PC part, it sends back a empty packet if it receives a packet), the sink
still will die.
I suspect that maybe there are some defects in UART. Did this also happend
to anyone before? Your help is appreciated.
