Hi,NS_Users！
when I trace the mac transmission time double
txtime=hdr_cmn::access(p)->txtime() in the function
WirelessPhy::sendDown(Packet *p) and I got
0.000000000000000(printf(file,"%.15f",txtime)).Please tell me why this happen?
How can I get the exactly txtime value? Thanks in advance!
Best Regards
