Re: [ns] command to create mac_802-11.o in Makefile

There isn't an explicit rule to make mac-802_11.o. The makefile falls back on the implicit rule to build a .o file from a .cc file, which is .cc.o: @rm -f $@ $(CPP) -c $(CFLAGS) $(INCLUDES) -o $@ $*.cc If you want to set that macro for all files in ns, you should do is to add "-Ddegub" to "DEFINE" in Makefile.in, re-run configure, and then make, or better yet, just run CFLAGS="-Ddegub" make That will set the "CFLAGS" variable in your system environment before running make, which will incorporate its value into the CFLAGS string that it uses. If you only want to set that macro on the one file, add a rule to Makefile.in similar to the following: mac/mac-802_11.o: mac/mac-802_11.cc @rm -f $@ $(CC) -c $(CFLAGS) -Ddegub $(INCLUDES) -o $@ $*.cc Then, re-run configure and make.

Re: [ns] transmit power - does it really control transmission range?
Hi Sita, In my opinion you dont define threshold like that. You need to ensure: 1. The receiving node can sense the signal. 2. If multiple signal arrive at the same time the signal to noise ratio is greater its threshold. You need to set three vars or use default vals with care: RXThresh_: Received signal strength has to be greater than this for the packet to be successfully received. CSThresh_: Received signal strength has to be greater than this for the packet transmission to be sensed. So, CSThresh_ should be smaller or equal to RXThresh_ for a real case. CPThresh_: With multiple signal being received the ratio of stregths of strongest signal to the second strongest one has to be greater that this. If it is not both are truncated. I think (check for yourself) in NS they check only the strongest two signals which is wrong in my opinion. It should be the original signal and the sum of all other signals. I think they do it in glomosim. -Atiur --- "Sita S. Krishnakumar" <[EMAIL PROTECTED]> wrote: > I am using two ray ground propogation.

Re: [ns] nam: command not found
Hi Arvind, In my case nam is present as ~/ns-2.32-allinone/nam-1.13/nam ie, /nam-/nam. But you dont have to worry about the actual path, a link is setup automatically as ~/ns-2.32-allinone/bin/nam. There is a link for ns in the same directory too. So, all you need to do is to add this /bin to your PATH variable. -Atiur --- Arvind Swaminathan <[EMAIL PROTECTED]> wrote: > Hi, > > Thanks for your replies.

Re: [ns] INFO SHARE
Hi Veerayya, looks obvious, but: 1. You can consider "hidden terminal" problem 2. Propagation? (a one-hop node that, in fact, is far way) I choose the first problem. Try to reduce node numbers or spread them more.

[ns] INFO SHARE
Hello Ns-users, Here I am sharing one of my experience with Ad-hoc simulations in NS-2.29, I would like know the reason for it. 1. The broadcast packets not reach all one-hop neighbours 2. Unicast packets does not reach the next hop The behaviour changes if the node position is changeg slightly. I have used TwoRayGround model as fading model and AODV as routing protocol If somebody has figured out why is this ? or is it a bug in NS-2 ? Please share the information to increase my knoledge.. Thanks in advance Mallapur Veerayya M.Tech(CE) Reg No. 06307416 IIT BOMBAY
