[ns] multiple udp packets being sent at the same time

Hi guys. I've been trying to simulate a wireless network. I created a udp agent and attached it to multiple nodes and a cbr for each node as well. For some unknown reasons every source is sending the same packet at the SAME time about 10 times. There are no loops no nothing its just being

Re: [ns] can't read Node_(20): no such variable

Hello Mahamadou, In your TCL script check for the number of nodes you have set initially and then check where you defined each node's X, Y, Z coordinates. you might have listed the coordinates of the nodes from Node 0 till node 20 and initialized the nn (number of nodes) to 20 which is

[ns] How to generate a topology in ns2

Dear Friends, How does one generate a topology of non-uniformly placed nodes, by non-uniform i mean that in some locations of the network alot of nodes are close and on other parts they are few and scattered. Of course I would need to know how to generate a topology in the first place, so

Hi Samira, I had the same question and i got the following reply from Mr. Keven Sheth that turned out to be useful. What he answered specifically is how to calculate the distances between to nodes, which uses the coordinates of the nodes by accessing them from struct mb_node in file

[ns] NS2 isn't cleaning the .o files with make clean, why ?

Dear NS Users, Can someone please tell me how you can retrieve the coordinates of the network nodes from a TCL file into C++. So is their some loop or something that can be written in C++ and traverses all the nodes and gets X, Y, Z, and how is it written. Hope you can help me. Thanks,

Hi Guys. I want to implement an algorithm for Wireless Sensor Networks (IEEE 802.15.4)in NS2. I don't know what protocol to use at the MAC layer, there's no such implementation of IEEE 802.15.4 in NS2! i tried using SMAC (already in NS2, inteneded for the use of WSNs) but it was goiving

Hi All, I've seen some implementations for WSNs in NS2 such as gpsr but it uses 802.11 as a MAC. I was wondering if anyone has any idea of the best package to use for simulating WSNs (its better if it functions over 802.15 which i know is implemented in the SMAC accompanying ns2). You're help
