[ns] Simulation halting after ARP request in Wifi, ns3
Hello ns users,
I am simulating a small Adhoc-wifi network of 4 nodes in ns3. Two nodes
are OnOff sources and other two of them are OnOff sinks. I am starting two
source nodes at the same time. The problem I am facing is that, after ARP
request the simulation just halts, not even a single data packet is sent.
Following is my script:
#include iostream
#include fstream
#include ns3/core-module.h
#include ns3/common-module.h
#include ns3/node-module.h

return 0;
}
Following is content of out.tr after simulation:

It appears that the ARP request does collide (I dont' know why?) since the
node 3 is receiveing the ARP request sent by node 0 for node 2. But
simulation doesn't carry on. This is the whole trace file that I have
shown.
Please help me in simulating more than 1 application in wifi ns3 because
any example does not show us how to do so.
Any help would be greatly appreciated.
Thank you,

[ns] MAC layer queue and Very slow simulations
Hi ns-users, First of all I want to thank you all for replying to my previous post. My simulations are taking days to complete. Here is my problem: I want that my queue at the MAC layer such that it is never empty, that is, MAC always has atleast one packet to send. So, what I did was increased the cbr rate as: $cbr($i) set rate_ 10Mb And since I don't want any payload so I set the packet size as: $cbr($i) set packetSize_ 1 Number of stations are 2000 in a LAN. 1000 are sources and 1000 are sinks. Time for the simulation is 10 seconds. This simualtion took me one day i.e. 22 hours approx to complete. But If I remove the packet size line i.e. set the packet size to default. then the simulation finishes within an hour. But my simualtions want the packet size to be less as possible and also always crowded MAC layer. I need help to fasten up the Simulations OR any other fast method for crowding MAC layer and small packet length in LAN. Any help would be greatly appreciated. Thanks in advance, Best Regards, Amit Soni Email ID: [EMAIL PROTECTED]
Re: [ns] Negative UID of the packets
Hi Ns-Users, Thank you Teerawat for your reply, but in my simulation, from 0-3.4 seconds th-uid() is positive but from 3.4 it goes negative. I think the most probably reason is that the packet uid space exhausts, but then why doesn't it shows some error. Any ways even if it goes exhausts is there any way to wrap around the uid's , I mean renew all the uid's. Thanks again, Regards, Amit Soni email id: [EMAIL PROTECTED] Hi Amit, Negative UID is a common mechanism in NS2. NS2 uses the scheduler to keep track of event. The mechanism is as follows: 1. When you schedule an event at a certain time, a positive uid_ value is assigned to the event. 2. When the event is executed, the uid_ is revert to its negative value. 3. Again, when you create another event, a new event with positive uid_ is created. Having negative uid_ simply means that the packet (or event) is being executed (e.g., transmitted to another node). Best, Teerawat P.S. There is one book for NS2.
