New Wireless Trace Formats
This information comes from “The ns Manual” (http://www.isi.edu/nsnam/ns/doc/) “Mobile Networking in ns: Revised format for wireless traces” chapter, and the “trace/cmu-trace.cc” file. Similar to the old format, in the new format wireless traces begin with one of four characters. This is followed by flag/value pairs similar to NAM traces. The first letter of flags with two letters designates the flag type:
- N: Node Property
- I: IP Level Packet Information
- H: Next Hop Information
- M: MAC Level Packet Information
- P: Packet Specific Information
| Event | Abbreviation | Flag | Type | Value |
|---|---|---|---|---|
| Wireless Event | s: Send r: Receive d: Drop f: Forward |
-t | double | Time (* For Global Setting) |
| -Ni | int | Node ID | ||
| -Nx | double | Node X Coordinate | ||
| -Ny | double | Node Y Coordinate | ||
| -Nz | double | Node Z Coordinate | ||
| -Ne | double | Node Energy Level | ||
| -Nl | string | Network trace Level (AGT, RTR, MAC, etc.) | ||
| -Nw | string | Drop Reason | ||
| -Hs | int | Hop source node ID | ||
| -Hd | int | Hop destination Node ID, -1, -2 | ||
| -Ma | hexadecimal | Duration | ||
| -Ms | hexadecimal | Source Ethernet Address | ||
| -Md | hexadecimal | Destination Ethernet Address | ||
| -Mt | hexadecimal | Ethernet Type | ||
| -P | string | Packet Type (arp, dsr, imep, tora, etc.) | ||
| -Pn | string | Packet Type (cbr, tcp) |
Note that the value for the -Hd flag may be -1 or -2. -1 means that the packet is a broadcast packet, and -2 means that the destination node has not been set. -2 is typically seen for packets that are passed between the agent (-Nl AGT) and routing (-Nl RTR) levels.
AODV Trace Formats
AODV traces begin with an “A”, followed by the AODV trace. This information comes from the “aodv/aodv_logs.cc” source file.
| Event | Abbreviation | Type | Value |
|---|---|---|---|
| Delete Link | A | %.9f _%d_ deleting LL hop to %d (delete %d is %s) | |
| double | Time | ||
| int | Index | ||
| int | Destination | ||
| int | Deleted Link Count | ||
| string | Link State (VALID, INVALID) | ||
| Broken Link | A | %.9f _%d_ LL unable to deliver packet %d to %d (%d) (reason = %d, ifqlen = %d) | |
| double | Time | ||
| int | Index | ||
| int | Unique Packet ID | ||
| int | Next Hop | ||
| int | Broken Link Count | ||
| int | Transmit Reason | ||
| int | Queue Length | ||
| Keeping Bad Link | A | %.9f _%d_ keeping LL hop to %d (keep %d is %s) | |
| double | Time | ||
| int | Index | ||
| int | Destination | ||
| int | Kept Bad Link Count | ||
| string | Link State (VALID, INVALID) | ||
I need awk script for new trace format of wireless.I visited mohit blog but those scripts give me single value for each run.I need a script which runs for number of times and give me values so that I can plot it via xgraph.
