I am trying to use the error model in ns2 with wireless links, I am using ns2.33. I tried the uniform error model and the markov chain model. No errors from ns but when I am trying to find the dropped packets due to corruption I can not find any of them using either the uniform or markov models. So please help me if I made any error in ...
I am trying to monitor a tcp flow using flow monitor. attach-fmon wants link object which is not available in wireless connections, how can I solve this problem ? are there any other solutions ? My code is here http://pastebin.com/f59241692 I got this error message eid@eid-laptop:~/code/ns2/noisy$ ns mixed.tcl num_nodes is set 3 INITI...
I'm try to add multi-interface in ns2 following the paper Adding Multiple Interface Support in NS-2. When changing the file channel.cc, I add code below: nextX_[this−>index()] prevX_[this−>index()] After making this change, I get the following error: In file included from mac/channel.cc:67: mac/wireless-phyExt.h: At global scope:...
Is there an existing tool to filter an NS2 tracefile according to nodes' locations? I.e. only show events for nodes between x1,y1 and x2,y2. ...
I am using NS2 simulator for doing some network simulation and having some problem while setting the MTU value ie maximum transmission unit. I want know what is the default value of MTU in NS2 and how can i change this value according to my need? I want to set different MTU value to observe the behaviour of TCP in different conditions. ...
hey i did a program regarding node creation and packet transmissionin ns2. I want to drop packets if energy is drained so please help me to find the solution for this and explain how can i drop packets........ ...
I'm using a discrete event simulator called ns-2 that was built using Tcl and C++. I was trying to write some code in TCL: set ns [new Simulator] set state 0 $ns at 0.0 "puts \"At 0.0 value of state is: $state\"" $ns at 1.0 "changeVal" $ns at 2.0 "puts \"At 2.0 values of state is: $state\"" proc changeVal {} { global state gl...
Hello all, I'm using NS2 to create some new classes in C++ and then link them to otcl. The linkage and everything works, but when I try to use the otcl variables in an object, I'm having a trouble. For example, suppose I have a class "Node" with the variable X. In the code I want to set this value and later on use it in some if-stateme...
I have built a simulation with five UDP flows, and i would like to make one flow suffer from link errors with a probability of 0.1 during the simulation. ...

Hi guys Does anyone know any code in ns2 which can give us residual energy of a node and also something for measuring the signal strength when we recieve a message. I'm very confused just let me know as soon as posible. Thanks in your advance. ...
Hi Developers, I want to integrate ns2 with a web server to show some kind of simulation results. Could anyone plz suggest if there's any middleware for this purpose? Google failed to return me any suitable result for this :( Also, if I plan to develop a middleware from scratch for the same purpose, is there any guideline to follow? In...
Hey, I installed ns-2.33, and then added the patches for Directional Antennas. And I downloaded a sample from: http://www.cse.iitk.ac.in/users/braman/tens/. When I run it the following error is given: invalid command name "Channel/Channel_802_11" while executing "Channel/Channel_802_11 create _o11 " invoked from within "catch "$...
I need a product to simulate network latency for testing mobile applications (in particular iphone and android). I plan to set up a wifi router connected to a linux box, and write a number of scripts to approximate different types of connectivity issues. So far, I've taken a cursory look at Netem and ns-2 (or its offspring ns-3). Nete...
I tried to run a simulation for wired-cum-wireless scenario. It is good when i use a single base station. But, when i use more than one, following error is displayed. --- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) --- _o92: no target for slot 0 _o92 type: Classifier/Port content dump: classifier _o92 0 offset...
