Installation of GPSR in Ns 2.29

Installation of GPSR:

For the GPSR installation, use the ns-2.29 patch: [ns2-hls-patch.tar.gz] which is given in gpsrinstall folder.

Unpack the tar archive. The new archive includes three files. The patch file, a short README file and a file about the changes done by applying the patch. Apply the patch from your ns-2 directory and execute the patch:
patch -p1 < <path to ns-2.XX-hls.patch>

Changes when establishing the patch:

The patch adds three new directories and some new files:

• The gpsr directory that includes the functionality of "greedy perimeter stateless routing".
• The hls directory. Includes all stuff important for hls to work.
• The locservice directory. Includes everything necessary for location services like HLS to work. Also included are the locservices GLS and RLS.
• The two C++ codefiles geo_util.h, geo_util.cc are added to the mobile directory
• gpsr.tcl is added to the tcl/mobility/ directory. This is important for establishing a gpsr agent.

Changed files:

• mobile/god.h / god.cc
• common/mobilenode.h
• common/packet.h
• common/agent.h
• common/ip.h
• trace/cmu-trace.h / cmu-trace.cc
• mac/mac-802_11.h / mac-802_11.cc
• mac/mac.h
• queue/priqueue.h / priqueue.cc
• tcl/lib/ns-mobilenode.tcl
• tcl/lib/ns-lib.tcl
• tcl/lib/ns-default.tcl
• tcl/lib/ns-packet.tcl

When you have applied the patch, there is a directory called utils in the new directory hls. There is a tcl script file included that should help you to get used to work with gpsr and location services. There are also some sample files included.
Before you continue, do a make clean, followed by make.

You may get some errors in the files folder Queue due to lines like

if ((p = strstr(v->name(), "ave")) == NULL) &&

              ((p =strstr(v->name(), "prob")) == NULL) &&

              ((p =strstr(v->name(), "curq")) == NULL) &&

              ((p =strstr(v->name(), "cur_max_p"))==NULL) ) {

Replace the lines as

if (((p = const_cast<char*>(strstr(v->name(), "ave"))) == NULL) &&

((p = const_cast<char*>(strstr(v->name(), "prob"))) == NULL) &&

((p = const_cast<char*>(strstr(v->name(), "curq"))) == NULL) &&   ((p = const_cast<char*>(strstr(v->name(), "cur_max_p")))==NULL) ) {

This error may occur in some of the files, replace all files and again try to run makeclean and make

You can start with the sample script hls.tcl. Execution: ../../ns hls.tcl
