Re: [ns] Cloning AODV
Hi,
I can tell another way which I think is simpler to do this clone stuff, for
your reference only.
You can directly change the AODV codes in the ns/aodv/ directory without
change the name of the directory and files (of course you'd better backup the
oringal codes first), and rebuild the codes.
This approach would cause less problems related to the makefile and
ns-lib.tcl kind of things, so maybe worth a shot.
good luck
Larry
Hello, NS-users:
I want to create a routing protocol according to AODV, so my first
task is to clone AODV. After seeing other ns-users' posts, i do my
work in following steps.
First, i copy all the files in $NS\aodv\ to a new folder called
aodv_lsa and rename all files (i.e. from filename.cc and filename.h to
myfilename.cc and myfilename.h), and then i change all the names of
C++ classes, packet headers, variables, TCL bindings, ...
Second, i make some essential changes according to
http://masimum.dif.um.es/nsrt-howto/html/

Re: [ns] program to place nodes in regula r shapes???
Hi, I think this can be done properly with Tcl scripts, using some node&link-setup and loop controlling code lines. For the convience of reusing, you can also write these codes in a seperate senario file and load it in the main simulation tcl files. Best Regards, Larry Hi everyone! In working with ns fhcf implementation and I must place my wireless nodes in such positions (co-ordinates X and Y)so that these nodes would create regular shapes: squares, pentagons, hexagons etc... Does enyone know any program which could help with this matter? Thanks in advance! Best regards! Mateusz -- INTERIA.PL dla kobiet... >>> http://link.interia.pl/f193b

In practice there is nothing like a transmission radius. If a node receives a packet depends on the propagation model. If you need a specific transmission radius (which btw is not really realistic) you can calculate the corresponding propagation parameters using the propagation.cc helper tool. Better setup the propagation parameters to reflect the conditions in the simulated environment and see what happens. Daniel.

Re: [ns] Getting data from wireless base station to cross to wiredstation
Congratulations Paul! I believe that after fixing your first "major" bug, your next NS2 hacking experiences will be done a lot faster. One very important helper for beating the NS2 learning curve is to study the other NS2 success stories, to try to grasp all the details and lessons learnt. These could be right the thing that one will need either tomorrow... or in a year's time. Now that you have the protocol working, you might want to combine and parametize the test script so that it is able to run both protocols in the exact same scenarios. > -Original Message- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf > Of Paul Vincent Craven > > A while back I asked about getting data to move from my wireless base > station node to my wired node.

The fixed routing protocol should have done it for you, on the fixed part of the network. Try other fixed routing protocols without your fix, to check what's happening: # http://www.isi.edu/nsnam/ns/doc/node304.html # types of protocols: Algorithmic / Direct / Dummy / DV / LS / Manual # Session / Static In this process you may find that the bug was your's, which is strange because your hierarchal addresses are OK, eg: 0.0.0 (W(0)) wired link 1.0.0 (BS) wireless link 1.0.1 (MH) your you might find a bug on the NS2 (step 7 of http://tagus.inesc-id.pt/~pestrela/ns2/ns2_debugging3.html) > 2.)

I've compared your code to DSDV's and NOAH's, and I can't understand why you couldn't use the same method: NOAH_Agent::forwardPacket (Packet * p) ... target_->recv(p, (Handler *)0); //line 985 ...

Re: [ns] Fwd: (hybrid ad hoc network) behavior of base stations
Hello, That occurs because gateways haven't been selected as MPRs by any node. Note that fixed nodes aren't included within the neighborhood of the gateways.

[ns] error when compiling a new MANET protocol
Hello ns users! I am trying to develop a new MANET routing protocol, following the steps described in the tutorial "Implementing a new MANET unicast routing protocol in NS2" .

[ns] LinkCache vs MobiCache
