To add a little more:
Sent, time, _node_, MAC trace, no-error, packet#, type, bytes, [(in hex) 
duration field (0 µs), receiver address, transmitter address and 
ether-type], ---, [(in decimal) IP source address:source port (255), 
IP destination address (-1):destination port (255), IP time-to-live (32)

[ns] Wired-Wireless Trace... message at MAC layer?

[Syed Faraz Hasan]

Hi everyone!

I simulated a wired-wireless scenario in NS-2. There is one wired node, 
connected to base station node. BS is further connected to wireless node. 
Wireless node is sending TCP traffic to wired node via BS. I get the trace file 
without error but I could not understand a few messages in trace file.

For example
What does this "message" mean?
s 0.035412973 _1_ MAC --- 1 message 90 [0  0 800] --- [4194304:255 
-1:255 32 0]
Only MAC trace and Wired Trace is ON
Can some one please help me on this.

A few starting lines of trace are as follows;
