Re: [ns] Drawing exponential graphs
Hi, These extracted from blog's Mohit : AWK scripts (.awk), which are used to extract the necessary information from trace files (.tr) are also useful to plot graphs using Xgraph (.xgr) utility of NS-2. However, the AWK scripts that are used to plot graphs differ from the AWK scripts that just print the values on the terminal. I will try to explain the difference between these two types of AWK scripts with the help of an example. Assume that we have designed a tcl script named “energy.tcl” which simulates a network for 100 seconds. We run this tcl script with the following command: *ns energy.tcl* After executing the tcl script we get a trace file (.tr) and a NAM file (.nam) i.e. “energy.tr” and “energy.nam”. Now we may have two scenarios as explained below: 1. We want the value of residual (remaining) energy of a node *at the end of the simulation*. (Here graph of Time v/s Residual energy is not required). 2. We want the value of residual (remaining) energy of a node *at each instance of time* i.e from beginning of the simulation to the end of the simulation. (Time v/s Residual energy graph is required to observe the decrease in the total energy of a node). For both of the above mentioned scenarios we need to design two different AWK scripts. However, the main logic to calculate the residual energy will remain the same. Only the way we print the values differs. Let *scen1.awk* be the awk file for first scenario and *scen2.awk* be the awk file for second scenario. scen1.awk should be designed such that when we run it by using the following command: *awk -f scen1.awk energy.tr* it should print the residual (remaining) energy of a node on the terminal. And scen2.awk should be designed such that when we run it by using the following command: *awk -f scen2.awk energy.trenergy.xgr* it should print two values in “energy.xgr”: time and residual (remaining) energy of a node. If you open “energy.xgr” you will notice that there are two columns created. In first column, values related to “time” are printed and in another column values related to “residual energy” are printed. The values in first column form X-axis of the graph and the values in second column form Y-axis of the graph (thus you get a graph of Time v/s Residual Energy). Give the following command to see the graph: *xgraph energy.xgr* Default background color of the graph is grey. If you want a graph with background color as white, give the following command: *xgraph energy.xgr -bg white Besides, you can plot graph by using gnuplot (search google gnuplot for more information). Hope it helps, regards. phathienhung. * 2011/4/11 兰天 lantian0...@163.com hi, I also work on the simulation of 802.15.4, I hope that we could discuss together Varrick At 2011-04-11 08:17:24，Mossy Mozila mossymb...@gmail.com wrote: Hie I'm also facing the same problem if it happens that someone helped you can you just post me the idea at mossymb...@gmail.com.

[ns] No Packet is exchanging usinng routing protocol Protoname.
Hello, I have been able to implement the Manet routing protocol (protoname) reading implementing a new manet routing protocol in NS2 . http://issuu.com/adioshun/docs/implementing_a_new_manet_unicast_routing_protocol_ I have got it to compile successfully but when i run a test simulation using it , i do not get any packets to be successfully transmitted. I printed out the routing table onto the trace file and noticed that the routing table is empty throughout the simulation. The same simulation file works fine when i use AODV or DSR for that matter. I am not sure why its not sending any packets. i did not get any errors when compiling protoname. I've sent an attachment of that tcl file with this mail. Please help me.I m a new user.please help.
Re: [ns] Change packet route in Nist MIH extension
I am working also with NIST module and have some problem can we collaborate on how to use NIST on TCL code ? please Pablo Gualda wrote: Hi, I have seen that some people have written about this with no answer, I am interested in changing the route dinamically in c++ code. I am trying to make changes in dsdv, In ns2.34 without Nist MIH extension, it works setting the next hop field in the common header, but with Nist, and multi interfaces, I cant do this (I Can but it doesn work like in the case without Nist MIH extension, It start sending packets to in a rare way). It icould be because Im not setting the correct route. In Nist MIH extension with multiinterface, the packets are sent between the interfaces? or I have to send packets to the multiface nodes too? Any help would be appreciated. Thanks in advance.

Hi, I have my AODV.tcl script running in order to compare AODV-DSDV-DSR the only change I have to make is to change the set val (rp) first for DSDV and then for DSR and leave the rest of the tcl code without any further change(as it was previously for AODV)?

[ns] cbrp - error when calling class $cls: $args $...
Hi all,
I am developping a cbrp code for ns2.34 and I thought that I did everything
good
when it compiled good, but when I try to use it I am facing the below error. If
anybody has an idea about this error, please do reply because I have no much
time left to do this!!! I have been trying to solve it but no matter what I do,
I still get the exact same error. It is something that has to do when the nodes
are being created and routing agents attached to them. I guessed to look at
ns-lib.tcl but I tried a lot of things unsuccessfully. I would be most happy
to share this protocol with you when it is finished.
Thanks soo much,
