[ns] One interface with two channels
Hello I'm trying to implement a new mac protocol, similarly with 802.11. Now I need to create one uplink channel and one downlink channel, to have simultaneously transmissions. To achieve that, I only found the perspective multi-channel with multi-interface, that is not what I want. What I really want is one interface with support to two channels, because I need to preserve just one mac layer per node. Is this possible? What I need to change to achieve this? I'm thinking to create a new add-interface method on ns-mobilenode.tcl, with two channels for one interface, is this valid? Thanks for any feedback and any help. -- Miguel Pereira
[ns] about two versions of setdest
Hello everybody. ns provides a tool named setdest generating mobility files automatically. (located at "ns/indep-utils/cmu-scen-gen/setdest") it has two verisons, one was implemented by cmu people in 1999 and the other is the modified version implemented by Michigan people in 2003. what I want to figure out are 1. whether each version makes sense to use 2. how different those two are, especially, how can i use version 2 as like version 1?? actually i tested two versions and found something awkward. i set the min speed in the version 2 "0.001" which would get the same result of zero min speed. and the min speed in the version 1 is always zero. so i expected the two results would be almost same. but really different results came out. hope somebody can help me with this matter. thanks -- Ginnah Lee Graduate Student Dept.of Electrical and Computer Engineering University of Maryland College Park, MD 20742 ++ Tel: +1-240-429-0080

[ns] doubt in executing tcl script in ns2.29 using cygwin/x
Hi, Initially,I was using ns-allinone-2.29 under windows.Usually I used to excute tcl script in cygwin window by typing startx and then later ns .tcl and I used to get nam output along with trace file(.tr file).But recently I have updated my cygwin with new features like xfig,ddd,emacs. But,when I type startx,cygwin/x:0.0 is getting displayed and when I type ns .tcl it is not displaying any nam window. Can anyone let me know what are the commands used to execute tcl script in ns2.29 using new version of cygwin. Thank you, pavikirthi
[ns] new protocol my ping
hello
i make some change in a ping example in order to try to compile a new protocol
, but it doesn't work i don't know why !!
i've only create new files myping.cc myping.h myping.tcl i put them in
ns-2.33/apps, and i've replace only ping by myping in all class for example
in myping.h
#ifndef ns_myping_h
#define ns_myping_h
#include "agent.h"
#include "tclcl.h"
#include "packet.h"
#include "address.h"
#include "ip.h"
struct hdr_myping {
char ret;
char nbhop;
double send_time;
};
class myPingAgent : public Agent {
public:
myPingAgent();
int command(int argc, const char*const* argv);
void recv(Packet*, Handler*);
protected:
int off_myping_;
};
#endif
i did all the necessary changement in
tcl/lib/default.tcl, common/packet.h..and in Makefile i add
apps/myping.o
tell me plz if i have to create myping.o or it's automaticly generated
i run ./configure
but when i run make oooh my dearest god a lot of error , i'm dispointed
look in to that :
configure: creating ./config.status
config.status: creating Makefile
config.status: creating tcl/lib/ns-autoconf.tcl

[ns] SIMULATION OF WLAN
NS users, I want to simulate IEEE 802.11b WLAN and see the plot between throughput vs number of stations. I need a topology like this: The mobile stations are randomly distributed in a circle with a radius of 100 meters and the access point is located in the center of the circle.The network is under a heavy load condition and traffic is evenly distributed across all the nodes in the network. Packets arrive the network according to the poisson distribution and simulation stops after 1 million packets. Can anyone please suggest me how to write tcl code for this. Please send me the tcl code or a part of tcl code for the above scenario. please help me. I need it urgently. Thanks in advance.
