Hi, I am new to TinyOS and i intend to work with the routing protocol. Right now, i want to calculate the link and end to end delay in a multihop net.
I am assuming that all the node are connected (via long USB cables) to PC. One idea i was contemplating was that, the message from a originator node could be time stamped with the PC clock time. At the receiver, the motes can get the PC clock time (OS is Ubuntu 10.04) at initialization (say booting) and then calculate the PC time, at any moment , by adding the mote time elapsed since booting. Finally, the time it took for the single hop transmission can be calculated by at the receiver by subtracting this time, with the one in the in-coming packet. I have looked up for the ways for accessing the PC time from the mote but could not find the right way. Can anybody please help me in it matter. Regards, Altamash Ahmed,
