ns-2 Code of ORMCC

Instructions to add the ORMCC protocol to ns-2

Copy the following files into the main ns directory:
ormcc.h, ormcc.cc, ormcc-avg.h, ormcc-avg.cc Download

In packet.h make the following additions:

below

#define HDR_DIFF(p)     (hdr_diff::access(p))

add the line:

#define HDR_ORMCC(p)    (hdr_ormcc::access (p))
#define HDR_ORMCC_CI(p) (hdr_ormcc_ci::access (p))

below
```
PT_REALAUDIO,
```
add the lines:
```
PT_ORMCC,
PT_ORMCC_CI,
```

below

name_[PT_REALAUDIO] = "ra";

add the lines:

name_[PT_ORMCC] = "ormcc_data";
name_[PT_ORMCC_CI] = "ormcc_ci";

In tcl/lib/ns-packet.tcl below
```
UMP
```
add the lines:
```
ORMCC
ORMCC_CI
```

In tcl/lib/ns-default.tcl add the following lines:

Agent/ORMCC set packetSize_             1000
Agent/ORMCC set minRate_                [Agent/ORMCC set packetSize_] ;# One packet per second
Agent/ORMCC set initRtt_                0.1
Agent/ORMCC set initRate_               [expr 2.0 * [Agent/ORMCC set packetSize_]/[Agent/ORMCC set initRtt_]] ;# 2 packets per RTT
Agent/ORMCCSink set packetSize_         40

In Makefile.in below

rtmodule.o classifier-hier.o addr-params.o\

add the line:

ormcc-avg.o ormcc.o\

Recompile ns with ./configure; make clean; make

A ns example script to test TCP-friendliness and drop-to-zero avoidance is available here.

*nix code of ORMCC

(See ns-2 code)

Note 1: This code is for test only. It just sends dummy data. However, it can be modified to send useful data.
Note 2: It now compiles on Linux and Solaris (using gmake). It should also compile on other Unix platforms with proper libraries linked.
