Dear Chenda. Sorry I had a mistake in an before mail. The reason for what Traceroute don't work in blip is because has been disabled in the case of TelosB motes for this reason:
"-- the motes don't send the ICMP time exceeded messages which are necessary for it. Two reasons -- (1) sometimes routing loops lead to a lot of dropped packets and so a lot of errors, which just make things works, and (2) I didn't want to use the code space." https://www.millennium.berkeley.edu/pipermail/tinyos-help/2012-March/054177.html So, to be sure if you are making multi-hops links, you can verify it seeing the TTL in your Terminal (e.g. the Linux command line). So if there is only one single hop, you only will be capable of see a TTL=15 for the case of two hops you will see TTL=14 and so on. This is a way to test the multihops with TelosB. Regards, Alex.
