Hello
"s" and "r" indicates that you send and receive the packets respectively.
RTR means network layer and AGT means application layer.
Here is the full description of trace format:
To find the interpretation of all possible trace format when you do the
wireless simulation, you'd better read the code of ns2 in file
*ns2home/trace/cmu-trace{.h,
.cc}* Mostly, the format would be as
ACTION: [s|r|D]: s -- sent, r -- received, D -- dropped
WHEN: the time when the action happened
WHERE: the node where the action happened
LAYER: AGT -- application,
RTR -- routing,
LL -- link layer (ARP is done here)
IFQ -- outgoing packet queue (between link and mac layer)
MAC -- mac,
PHY -- physical
flags:
SEQNO: the sequence number of the packet
TYPE: the packet type
cbr -- CBR data stream packet
DSR -- DSR routing packet (control packet generated by routing)
RTS -- RTS packet generated by MAC 802.11
ARP -- link layer ARP packet
SIZE: the size of packet at current layer, when packet goes down, size
increases, goes up size decreases
[a b c d]: a -- the packet duration in mac layer header
b -- the mac address of destination
c -- the mac address of source
d -- the mac type of the packet body
flags:
[......]: [
source node ip : port_number
destination node ip (-1 means broadcast) : port_number
ip header ttl
ip of next hop (0 means node 0 or broadcast)
]
