[ns] any multipath routing protocol source code needed
Hi, Does anybody have a source code for any multipath routing protocol? I try to contact the author but no respond. How can I get a source code for any of this.. eg : SMR, RMPDSR, MAODV, MMR, MSR etc.. if somebody have the source code for any of this protocol, this will help me lot. Thanks
[ns] specifically send data from node to node
Hi ns2 users, Referring to wireless example in ns2 (wireless.tcl or wireless-test.tcl), this examples are using cbr traffic generator to generate a traffic so its look like simulation during transmission. I have few problems. 1. Is it possible to send real specific file (.doc, .jpeg, .mp4 etc) 2. How can I specificly set to send data from node to node. (eg: transmit from node 1 to node 9) 3. How can I trace how the file/data is broadcasting from sender (node 1) to another node and its broadcasting to another till received by destination (node9).
[ns] specific packet transfer
hi.. By using examples in ../tcl/ex/wireless.tcl, how can if specifically we want to sent data (packets) from node 5 to node 45 only. This is because this example shows that packets are send and broadcast from one node to another without any scenario. In real scenario, only few nodes may send data to specific destination.

[ns] multipath DSR
Hi.. Does anyone know where I can find an implementation of any Multipath DSR for NS-2. There is a lot of paper that extend DSR to be multipath such as SMR, RMPSR, EDSR and etc. but i still didnt find how to implement it. thanks.. My system : FC 6 2.6.18-1.2869.fc6 ns2.30 - You rock.

[ns] DSR routing protocol
Hi ns users.. I still confused, when we run ~/tc/ex/wireless.tcl as default, they are using DSR routing protocol [set opt(rp) dsr ]. But in order to implement DSR routing protocol, how did this file (wireless.tcl) have a link/connection with ../ns2.30/dsr directory ? This is because even though ../ns2.30/dsr directory is deleted, wireless.tcl can still working. How can we simulate/test DSR routing protocol? Is it running wireless.tcl means we already implement DSR routing protocol? Thanks for any explanation.

[ns] transfer real file
Hi ns expert.. I have 2 questions. How can we change the default size packet (512 bytes) while do MANET simulation? Is it possible to transferring real file (.doc, .jpg, .mp3, .mp4, .avi and etc..) from specific source to specific destination and simulate in ns2 using DSR protocol? If yes, how could it be implementing? My system : FC 6 2.6.18-1.2869.fc6 ns2.30 - Looking for last minute shopping deals? Find them fast with Yahoo! Search.
[ns] DSR algorithm
hi all.. In DSR routing protocol, there are 2 phase, which is route discovery and route maintenance. Roughly, if a source want to start communicate, it will check a route cache to determine whether the route already exist or not. If the route expired or don't exist, then they will initiate a route discovery process by broadcasting a RREQ. Then the neighbors will forward the RREQ to another node untill it reach the destination. The destination then response with RREP and send back to the source. Once the source received RREP, the communication will start. The algorithm also involves updating routing table, set timer,accumulating the address of each node between source and destination, rejecting a loop route and etc. I try to explore ../ns2.30/dsr/ but I didn't find the file that described/written this algorithm. 1. How the example in ../tcl/ex/wireless.tcl is link with ../ns2.30/dsr/ ? 2. In which line wireless.tcl called the procedure or agent in dsr directory?

[ns] modify DSR routing protocol
Hi ns users.. I have run ../tcl/ex/wireless.tcl with dsr option. How can I modify DSR routing protocol it self? Which file should I 'edit' to change the routing protocol algorithm? Which file is used to define the routing algorithm? After I edit ../tcl/ex/wireless.tcl to add with nam simulation, I notice the simulation of DSR protocol is not like the theory. Any explanation is highly appreciated. thanks.. My system : FC 6 2.6.18-1.2869.fc6 ns2.30 - Looking for last minute shopping deals? Find them fast with Yahoo! Search.
[ns] which routing protocol is used in real ad hoc network
When we are creating ad hoc network (tools such as in windows) to make peer to peer network, which type of routing protocol (DSR,AODV, DSDV, etc...) are actually using? Is it true that in Windows they does not do any routing in ad-hoc mode. So what is the purpose of other routing protocol in ad hoc network (DSR, AODV, DSDV, DYMO, etc...). as we know this protocol is good and people always enhanced it. some of them are using multipath to distributed traffic load (sound good).

hello...
i try to implement this script but i've got an error
(FILENAME=../out.tr FNR=24960) fatal: division by zero attempted
looks like this line
delay=sum/recvnum
give an error when 'recvnum' is 0, where recvnum++ are not functioning. any
idea?

[ns] wireless.tcl vs wireless-test.tcl
What is the different between example ~/tcl/ex/wireless.tcl and ~/tcl/ex/wireless-test.tcl ? I found that the different is not just the number of nodes (50->3), sim time, movement file and traffic generator. some of the proc (proc create-god and proc cmu-trace ) are not used in wireless.tcl. some of the external file (source ../lib/ns-mobilenode.tcl, source ../mobility/$opt(rp).tcl, source ../lib/ns-bsnode.tcl, source ../mobility/com.tcl). Does anybody can explain why this different must be made rather than just change the number of nodes, sim time, movement file and traffic generator only? many thanks..

[ns] modified DSR protocol and extract out.tr script
hello... Theoretically if we are using dsr protocol, the route discovery and route maintenance are involved. its also involved RREQ, RREP and RERR.. contain routing table, packet detail information and many more. But regarding to ~tcl/ex/wireless.tcl (using dsr), i didn't find where all this function is calling. It may be a big help if anyone can give your modified ~tcl/ex/wireless.tcl and awk/perl script to extract the ~tcl/ex/out.tr to get some network analysis such as delay/jitter/packet send/received/etc so i can learn from it. your help is valuable for me. thanks..

I'm new user for ns2 and I've ns2 2.30.. I want to run the sample of the
script in few ad hoc routing protocols such as AODV, DSR and DSDV that is in
the directory ../ns-allinone-2.30/ns-2.30/aodv or dsr or dsdv. I run this
script by typing ' ns aodv.tcl ' but seems like it's not working and I got an
error like this.
invalid command name "Agent/rtProto/AODV"
while executing
"Agent/rtProto/AODV instproc init args {
$self next $args
} "
(file "aodv.tcl" line 19)
Is it possible to me to run this script? (aodv.tcl, aodv.cc, aodv.h). What is
the command I should use for?
How can I run the script for dsdv directory that contain dsdv.cc and dsdv.h
file?
