HELP WITH MODIFYING TCL FOR MOBILE IP SCENARIOS

2009-07-09T11:49:44Z

i forgot to mention that the original scenario is such that there are two base stations...one mobile node
and two wired nodes.the mobile node moves from base station to the
second base station.the two base stations are connected to a wired node
which in turn is connected to a second wired node
i m using ns2.33 & cygwin 1.5.25-15

i need help with this.....
I have the code to simulate mobile ip scenario.The code is attached and also pasted below..
i need to modify the code to do the following;
1.) mobile node and a base station with the mobile node withing the bs range.
2.) further modification such that i have a mobile node communicating with a base
station and the base station is connected to a wired node
3.) a further modification such that a mobile node communicates with a base station and the base station is connected to a wired node in which the wired node is also connected to another wired node

thanks.

Re: 802.11 10Mhz Channel

2009-07-09T10:23:43Z

Hello,

I would like to submit for code review the attached patch implementing half
and quarter-clocked Wifi operation using 5 and 10 Mhz channels spacing. We
would be glad to merge this new functionality in the main branch if ns-3
developers think it may be interesting for other people. The following files
have been modified (ns-3-dev):

src/devices/wifi/interference-helper.cc
src/devices/wifi/interference-helper.h
src/devices/wifi/wifi-phy.cc
src/devices/wifi/wifi-phy.h
src/devices/wifi/wifi-phy-standard.h
src/devices/wifi/yans-error-rate-model.cc
src/devices/wifi/yans-wifi-phy.cc
src/devices/wifi/yans-wifi-phy.h
src/helper/nqos-wifi-mac-helper.cc
src/helper/nqos-wifi-mac-helper.h
src/helper/qos-wifi-mac-helper.cc
src/helper/qos-wifi-mac-helper.h
src/helper/wifi-helper.cc
src/helper/wifi-helper.h

Apart from the modifications pointed out in the previous email posted some
weeks ago, we have also modified some of the wifi helpers. In order not to
make the user set weird values for the MAC parameters (slot,sifs, etc) from
the script, we have modified the WifiMacHelper incorporating two new
functions (Configure80211_10MhzParameters and Configure80211_5MhzParameters)
that allows the user to automatically select the default MAC parameters for
5Mhz and 10Mhz channel spacing (we have also moved the function SetType and
the ObjectFactory m_mac from NqosWifiMacHelper and QosWifiMacHelper to
WifiMacHelper).

Looking forward to your comments.

Best regards,
Ramon Bauza.

> Our research group at UMH, it is charge of implementing the 802.11p (WAVE)

Hi to all.

I am trying to implement a agent. I wrote the C++ code and recompiled with
no errors but when I try to attach the agent to a node I
get this error:

while executing
"Agent/IMS create _o86 "
invoked from within
"catch "$className create $o $args" msg"
invoked from within
"if [catch "$className create $o $args" msg] {

return ""
}

error "class $..."
(procedure "new" line 3)
invoked from within
"new Agent/IMS"
invoked from within
"set ims [new Agent/IMS]"
(file "ping.tcl" line 41)

I have attached the source code files. Can anyone help? What modifications
do I need to make to already existing files?

Canceling Events vs. Handling Events

2009-07-09T01:31:30Z

Hello,

I am developing some protocol extensions utilizing a keep-alive (recieve a packet every n seconds, if there was no packet for n+x seconds consider the sender dead).

When designing an implementation, I thought about the scheduler: I read somewhere in the manual, that inserting and deleting events may be costly. So now I am faced with two options:

- Have a single periodic timer for each node that when fired performs all pending actions.
- Have a separate timer for everything that needs to be timer-handled and have a receive-event of a keep-alive-packet cancel and reschedule the timer to the appropriate timeout.

Both are okay with respect to my protocol. I am expecting the keep-alive timeout to be reached almost never, so the timer handlers will hardly ever be run (second case) or have anything to do but calculate what actions actually are pending (first case).

Which would make my simulation run faster?

Regards,
Damian Philipp

Re: ns 2 agents

2009-07-09T01:20:25Z

I did play with the headers to test my own protocol. As far as I know
NS you should be able to modify your own header information to add
what you need. I am not enough savy to explain how I did it but I
found this manual really helpful to understand how NS handles the
headers. It also contains some examples that you can use as starting
point.

Let me add few words.

First of all, I believe that the model validation is a research activity
which can't be automated or restricted to use some build-in "Validation
toolkit". IMHO the best thing we can do is to encourage a companion "The NS-3
Foo Model Validation" paper(s) for every foo module. The recent 802.11b PHY
model is an excellent example of this, see
http://www.nsnam.org/~pei/80211b.pdf M.b. we should create and maintain a wiki
page listing all available models together with references to their validation
reports (see e.g. http://www.scalable-networks.com/pdf/QualNet_Library.pdf for
a nice table of all available models). When model is validated, usual
regression tests (both unit and functional) can be used to assert that it is
not broken. To summarize -- I propose do not create any kind of validation
toolkit, rather than encourage and collect references to the validation
efforts.

Agree.

Existing test.h + waf --check unit test facility just fits my needs and is
not worse than boost::test + cmake/ctest .

Why not?

Personally I'd like to see (finally) usual green-red html table like

http://buildbot.net/trac/wiki/ScreenShots with optional cpu time / memory

Why not interface with dedicated statistical systems like R
(http://www.rproject.org/) for data analysis? I don't believe that we really
need to create one more homegrown histogram implementation, to say nothing
about hypothesis testing.

ns 2 agents

2009-07-09T00:18:36Z

Hi to all,

I am trying to simulate a simple call flow in ns 2. Something like the
one attached. My idea is to create a new packet header with one int
value and one agent for each node. Each message in the call flow is
given an ID (1,2,3...). The first agent sends the first packet with
the ID=1 to the second node. The agent on the second node receives the
packet and sends one packet back (ID=2) and one packet to the third
node (ID=3). The procedure continues in the same way.
I created the packet header successfully but i have some problems with
the agents. Has anyone done anything similar? Can anyone help me?

open issues for ns-3 testing

2009-07-08T22:15:06Z

We last left off the testing discussion [1] prior to ns-3.5 release,
when we discussed the relative merits of running the tests from within
or outside of waf. However, there are still several issues that need to
be addressed before we could move towards a merge of a new testing
framework.

I tried to collect and summarize below what I understand to be many of
the remaining issues, and maybe Craig and others can respond or add to
the below list, and propose their requirements or goals.

Here is some prototype code that Craig has been putting together (it is
in separate repos):
http://code.nsnam.org/craigdo/ns-3-test-patches/file/e6a504a6568e/test.patch
http://code.nsnam.org/craigdo/ns-3-valver/

To recap, we already have a unit test framework, and a regression
testing framework for trace-based comparison of our examples. We don't
have a good place yet for validation and verification tests, we don't
have good examples to point to for how to write more complicated tests
(including stochastic tests), and further, we would like to not lean too
heavily on simply comparing pcap trace files for regression or
validation purposes, so we need a better way for generating, saving, and
comparing input and output test vectors that are more specific than
packet trace dumps.

Here are some lingering issues.

1) what is the overall plan for where this test code lives, and how does
it relate to existing test.h and test.cc? Should existing src/test be
moved to src/core?

2) Why not just borrow one of the existing GPLed testing frameworks and
reuse it here? Which ones have we looked at for comparison?

3) How are non-trivial output test vectors (they could be trace files,
long sequences of numbers or timestamps, etc.) going to be stored?

4) What is the story for waf integration, if test.py is retained? In
particular, what kind of front end could waf provide for test.py script?
In a previous post, I suggested that basic modes of test.py could
still be invoked by ./waf --check, ./waf --test, ./waf --regression
(etc.). Are the issues of accessing the configuration cache and of
running programs through waf (or not) settled?

5) Related to this, what is the expected API and granularity for running
these tests? Do we have different levels of testing that have simple
APIs (such as the above sequence of waf commands)?

6) Can we review some really simple examples (e.g. in samples/
directory) showing different examples of what different types of tests
would look like? What about a TCP model verification example?

7) Where do more complicated test and validation programs (i.e. the
actual tests) reside? src/test?

8) What about Mathieu's comment recently about having a mode that dumps
a lot of trace locally (without downloading saved regression traces) for
more extensive regression testing before a checkin?

9) What output do people want to see, typically (Gustavo had made a
comment about minimal output for successful tests and verbose outputs
for failed tests)?

10) Can we avoid baking in a GSL dependency in case we want to rewrite
histogram or chi-squared routines ourselves in the future?

11) Mathieu remarked early on that it would be nice to factor out the
chi-squared testing tools from within the random number tests, so they
could be used elsewhere.

Hi all!
Please could anyone help me with this? It is really important.
How can I get the power of the signal a mobile node receives from a base station as it moves in the topology??
Is there a c++ function I can call from my code?
Thank you very much in advance!

Re: Change the value of dataRate_ in Mac/802_11

2009-07-07T16:10:15Z

Are you setting it *before* creating the nodes?
If dataRate_ is not set when the nodes are created, they use bandwidth_ (defaults to 1Mb) instead.

Re: ipv6 plans for ns-3

Currently, https://svnet.u-strasbg.fr/hg/ns-3-ipv6 is very outdated.
Two day ago I begin to work with up-to-date ns-3-dev and port some of
the IPv6 components. It is located at
https://svnet.u-strasbg.fr/hg/ns-3-ipv6-2nd (not publicly available yet
but I will unlock access tomorrow or next monday).

For the next release, I really would like to have IPv6 routing, ICMPv6
(+ neighbor discovery protocol), UDP, IPv6 applications such as UdpEcho,
basic examples. If I had time radvd application to have IPv6 address
autoconfiguration, multihoming.
The features delayed will be TCP (if we can not find a good and easy
solution to integrate it nicely), IPv6 header extension (fragmentation,
loose routing, ...).

As I have a lot of work for my job arround wireless sensor network, I
can not work as long as I want on ns-3. But I will do my best during my
spare time on my holidays (tomorrow) to propose a working IPv6 stack.

For ns-3-ipv6-2nd repo I have also integrated Ipv6InterfaceAddress,
Ipv6Interface, NdiscCache. For routing code located in src/node, I think
it will be exactly the same for IPv6 (except changing Ipv4* to Ipv6* ).

For transport protocol, the main problem is (if I remember correctly)
that Tcp/UdpL4Protocol' and Tcp/UdpSocketImpl functions take Ipv4Address
arguments. We already have some discusses here with Mathieu but we have
not found a good solution to handle this. By the way same problem for
IPv4EndPoint / Ipv4EndPointDemux which majority of code will be duplicated.

To resume, I will open my private repository next couple of days. I will
continue to read code about recent IPv4 refactoring and implement
routing stuff (Ipv6L3Protocol), ICMPv6 (and neighbor discovery protocol)
and wait about transport protocol problem. Now all of us interrested in
IPv6 can begin to find a nice way to handle transport protocol in both
IPv4 and IPv6 without copy/paste code. And to finish It will be really
good if we can put great efforts on IPv6 integration for ns-3.6 to bring
ns-3 users the power of IPv6 ;)

hi all,

i want to change via tcl the value of rate in Mac/802_11 ...

For exemple when i set :
Mac/802_11 set dataRate_ 1Mb
the dataRate is really 1 Mb but after if i want to change the datarate to 2Mb
Mac/802_11 set dataRate_ 2Mb

AODV local repair

2009-07-07T04:19:28Z

Somebody knows how to modify local_repair() function?
In local repair mechanism when a link failure happens on an active route,
the first node upstream of that break (the predecessor) chooses to repair
the link locally. I wish to choose ANYTHING node upstream of that break and
no only THE predecessor.

*AODV::local_rt_repair(aodv_rt_entry *rt, Packet *p) {
#ifdef DEBUG
fprintf(stderr,"%s: Dst - %d\n", __FUNCTION__, rt->rt_dst);
#endif
// Buffer the packet

rqueue.enque(p);

// mark the route as under repair
rt->rt_flags = RTF_IN_REPAIR;

sendRequest(rt->rt_dst);

// set up a timer interrupt
Scheduler::instance().schedule(&lrtimer, p->copy(), rt->rt_req_timeout);
}
*
I wish before *rqueue.enque(p);* to be called, the predecessor node bring
down the route for to third predecessor node, for example, and only after
that make *rqueue.enque(p); *then after do send requests. Anybody help me?*

Re: Problems with 64bits platform

2009-07-07T03:28:53Z

Our problem appears when, in the 64-bit machine, we simulate multicast scenarios.

1. With PIM-DM protocol, when the source sends packets, all the nodes receive them, because Prune messages are sent very frequently (despite we have changed the prunetimeout variable to a large value). We have also checked that after a join-group action, no graft message is sent. So we conclude the management of the multicast groups is not running OK.

2. Now, we have also changed the multicast protocol to PIM-SM but it doesn't works in the 64-bit machine.

Any help is welcome.

Re: mcps_data_request and losses

2009-07-07T02:13:01Z

Hello,
Thanks for your proposition. I'm not near the computer I use for work but
I'll explain.
In my Tcl script, I call mcpsDataRequest to send frames. In the command
function of SSCS, I defined the mapping and made the call to
MCPS_DATA_request which in turn calls mcps_data_request. The issue I was
facing was that with 3 nodes, I had 99% packets successfully sent which was
just impossible. I checked the call to MCPS_DATA_request and noticed that I
had set the handle to 0. Since the handle was used later on to direct to
MCPS_DATA_confirm, I never got to that point as soon as there was one lost
frame. So the first two nodes to fail in sending a frame will never recover
from it and the last one will continue sending, leading to a near zero loss
ratio.
I don't really know awk. I use databases to process my files.

Re: Problems with 64bits platform

2009-07-07T01:36:40Z

I have only tested multicast examples with DM protocol, whit nodes
joining and leaving the group. I think the control messages of the
multicast protocol (prune) don't work well. I tried to change the period
of sending prune messages and the animation doesn't take it into account.

I tried to change it with this sentence and it doesn't work well.
DM set PruneTimeout 200 (large number to avoid sending prunes).

The nam animation shows a prune sent hundred of times per second and the
joinings and leavings don't take effect. The nessages are broadcasted to
all the nodes all the time.

The same scenario in a simple PC with 32-bit ubuntu an a 32-bit
processor works well

Any help will be welcomed.

Best regards
