[ns] Performance change due to change data order in packets header: Could anybody explain???
Hi all, I have modified AODV protocol to support other routing metric than hop-count, at the final stages of performance testing I have realized the following: I have added new fields to RREQ and RREP packets, lets say I have added three quantities of type double (x, y, z) to the RREQ to allow intermediate nodes to calculate the new route metric. What I have realized that the protocol performance will be different for the following two cases: -- if I have added these values as an array to the RREQ header (i.e.double new_metric[3]), -- if I add them as a three elements (i.e. double x, double y, double z). Also if only one element of the array is filled (i.e. new_metric[0], for example) the performance will be different from having all array elements are filled. I am measuring the total network throughput, the results are different for different RREQ format elements arrangements. Can any body explain this to me? what is happening here?

[ns] Help is needed plaese regarding ns-2 nodes communication
Hi all, I am simulating a static single-channel ad-hoc network in whch the transmission range is set to 150m and the interference range is set to 300m (using thershold tool in ns-2). The used protocol is AODV, what I have noticed that brodacasted packets can be heard successfully from nodes at distance > 150m (about 200m). This has created the problem that RREQ set paths between nodes with hop distance of around 200m, when this node used the stored path toward the source to send the RREP the RREP will be dropped (not heard by the node that lie on distance > 200m). nodes are oranized in a gird with distance between adjacent nodes = 100m, I have tried to reduce this distance and to increase it but the performance is still very poor. Can anybody explain things to me. settings of communication are as follows: /*- Phy/WirelessPhy set CPThresh_ 10.0;# capture threshold Phy/WirelessPhy set CSThresh_ 2.312e-11 ;# Carrier Sensing threshold, 300 m is the interference range Phy/WirelessPhy set RXThresh_ 1.533e-10 ;# receiver signal threshold, 150 m is the transmission range Phy/WirelessPhy set bandwidth_ 11Mb;# channel bandwidth (UNUSED!)

[ns] Abour CBR in wired-cum-wireless
Dear all, I have noticed something for CBR traffic generation in wired-cum-wireless scenarios. When the source of the data packets is wired hosts the number of generated packets exceeds the expected, that is if the interval for the cbr source is 0.1 and the simulation time is 15 sec, the genrated packets during this interval is 1500 packet instead of 150, however, when the cbr source is attached with a wireless node the number of generated packets is 150 (correct). I am recording the number of packets arrived at the MAC layer and I have realized that in case of wires source at each time instance (0.1, 0.2, 0.3, ...) the number of arrived packets is 10 instead of 1 (as in case of wireless source). can anybody explain?

[ns] Help with wired-cum-wireless extensions of ns-2
Dear all, I am working with a scenario where four domains are connected with each other with four wired APs, each domain contains a set of static wireless nodes. However, my target is to allow a wireless node to select the AP to which it will associate based on the congestion status of the AP. So, in this case mobile IP will be of no benifeat for me where its association is based on the signal strength recieved from the AP (based on distance between the mobile wireless node and the AP). How can I allow such dynamic AP association in my code? can anyone give some useful hints either on this issue or on the implementation of wired-cum-wireless extension of ns-2?

[ns] Working with Wireless Mesh Networks
Dear all, Have anybody simulated a wireless mesh network topology in which internet gateways, backbone routers and mobile clients ar incorporated in dynamic behavior? by dynamic behavior I mean that clients are not incorporated in routing thay only send data packets to the routers, also a client can change the router with which it is associated (due to movement). In addition, the routers can select the destination gateway dynamically during run time based on the network conditions (not via tcl in the script). In other words, I want to simulate a network similar to real life networks behavior (such as MIT roofnet network where gateways send advertisments and routers select the best gateway based on signal strength).

[ns] About Multi-interface support howto, by Ramon Aguero
Deal all, Have anybody worked with Multi-interface support howto, by Ramon Aguero and used it to support one of the routing agents that exist in ns2, e,g AODV, DSR, etc. ? If so, have you encountered the bug of 'Scheduler:: Event UID is not valid'? if so, please provide me with some guidlines of how to solve this error? Thanx, Ghada - Looking for a deal?

[ns] Scheduler: Event uid is not valid
Dear all,
I am working with ns-2 2.31, I have added the multi-interface capability
according to Multi-interface support howto, by Ramon Aguero
I have modified the routing agent (I have worked with AODV) to support
broadcasting packets on all interfaces as follows:
if(nIfaces) {
for(int i = 0; i < nIfaces; i++){
Packet *p_copy = p->copy();
Scheduler::instance().schedule(targetlist[i], p_copy, 0.);
}
Packet::free(p);
}
when I run my simulation scenario ( which is a static grid topology of 20
wireless nodes)
I got the error of:
"Scheduler: Event uid is not valid" at time 67 sec of the simulation time.
I have searched the mailing list and the available sources about this error,
I have fixed all MAC bugs (most of them are already fixed in the ns
distribution), then I have found a FAQ in which the following is stated:
"2. You are dealing with packets. A packet is also a kind of event to be
scheduled and a UID is associated with it. When you create a copy or alloc
again before freeing it, due to the same packet with a positive UID, it cannot
be scheduled again. "
So, I gussed that the error is in copying the packet to be sent on all
interfaces (in the modifed code presented above). So, I have modifed that code
as follows to free the copies of the packet:
if(nIfaces) {
for(int i = 0; i < nIfaces; i++){
Packet *p_copy = p->copy();
Scheduler::instance().schedule(targetlist[i], p_copy, 0.);
Packet::free(p_copy);
}
Packet::free(p);
}
but when I run my simulation scenario I got:
" segmentation fault 'core dumped'"
I am sure that the error is in the routing agent module, since I have run
simulation scenarios without the modified AODV and it worked, but I cannot
congifure where the bug is.
Is there anybody have worked in multi-interface support for AODV? have you
faced such problem in your testing?
any useful comments and hints will be highly apreciated.
Thanx,
Ghada

[ns] Recompiling ns-2 with 'make' does not work
Hi all, I am facing a problem with recompiling ns-2 after midifying its code, where after changing the code I run: 'make clean' 'configure' 'make' But mothing happen (i.e. no compilation takes place where ns-2 is still the one before modification, so changes does not take effect). Now, I run ./install for making the new ns2 with the new modifications taking its effect. The problem is in 'make' where it does not work, I am using ns-2.31 under windows xp SP 2, How can I solve such problem? is the problem in cygwin? or in the static compilation since the static compilation is disabled via the configure command.

Re: [ns] Modify the trace file format in ns-2
I have edited the 'new-trace' itself (I have appended an additional information for it, So in additional to the original info displayed by it there is the data rate). Regarding 'make clean' every time I run it it give error "cannot delet tcl it is directory" I do not know why that? By your argument do you mean that I must write a new trace format and add what I need it? and I sould not edit the 'new-trace' format? Thanx, Ghada Matthias Kuhnert <[EMAIL PROTECTED]> wrote: I did not understand, what you exactly modified/tried to do. To get the new trace format, you have to include in your tcl script a statement similar to "$ns_ use new-trace", depending how you named your simulator instance in the script. Then via some statements in the cmu-trace implementation the new trace file format is taken. You don't have to and must not change anything of the cmutrace for that purpose! The newtrace variable is initialised via the tcl, so it will be set on runtime - therefore a change of the variable in the c++ part doesn't change the behaviour of the trace during runtime... The configure is superfluous, if you did not add anything new! If you changed anything on the files, the only command additional to make, is a "make clean", to resolve on dependencies!

[ns] Suggestion -- Needing help about the real channel propagation model
Dear all, I have added your implementation of the realistic channel propagation by Wu Xiuchao for ns-2. I added the code and modify the required files then I run: make clean configure make make install. But when I attempt to use it in my code, i.e. ErrorModel80211 noise1 -91 for example, when I run the scenario I got the following error: invalid command name "ErrorModel80211" while executing ErrorModel80211 noise1 -91 can I ignore the use of these commands and add default values for them in the ~/tcl/ns-default.tcl file, and these values will be used by the mac layer, i.e. the values are hardcoded within the simulator and every time I modify them I must run configure then make, Does this enough and correct?

[ns] About patches added to ns-2
Dear all, I have installed a patch for ns-2 2.31, many failed hunks were appeared, I have edited them manually, but some of these hunks modify the .Z files that exist in the ~\tcl\test directory (example ~\ns-2.31\tcl\test\test-output-mcache\media1.Z). I am viewing the patch using a text editor, however the modification for such files is unreadable, so I cannot know where to add them. can anybody help me in how modifying such files? Or, do we need to modify these files to make ns-2 works correctly under the added patch? (I think that these files is a test suites for ns-2, i.e. not part of its source code) is this correct so I do not need to modify such files? Thanx, Ghada - Tonight's top picks.

I am managed to use ns-2.31 (since I want to use the lates version where many

You find this information in the patch file itself. Open the patch file
with any txt editor and see the changes made to classifier.cc. Usually, the
original lines in the files begins with - , and the new lines (changes) begins
with + or !.

If make or make distclean are not working because makefile is changed, you

Re: [ns] How to add new C++ classes to NS-2 2.31?
Hi, I have did this where I have added this line to the Makefile, then I opened cygwin and enetred the ns directory where I run configure then make, the Makefile were modified by the configure command. My question, the Makefile was changed were the line which I have added have disappeared, can I follow the same procedure for future additions and modifications?

OK! how to create Ricean.o? I have told u before that when I compile it with gcc many errors appears that said many required classes (included in Ricean.h) are not found in mobile directory, how can I do that under windows (using cygwin)?

[ns] How to add new C++ classes to NS-2 2.31?
Dear all, I am new to NS-2, and frankly I am still in the learning phase to use it in my Master Thesis, I am trying to include the .cc and .h classes of the Ricean propagation model within the simulator. I am working under windows (using Cygwin), and I have no .o file of the classes, I have put the classes in the mobile directory in ns, but when I am trying to compile them, a list of errors appears since many of the included classes (such as wireless_phy.h) is not exist in mobile directory. Then how can I include this class with ns-2? I have tried ./install (reinstall ns-2), also I have tried to run configure then make, but nothing work, and still there is no .o file generated nor NS-2 has added the new class. Please can anybody help me and give me simple instruction to that under windows ASAP?
