Re: [ns] ns/nam: respresentation problem when definingposition-fixed nodes (NEW question)
Hi,
Thank your very much for your reply.
It is a good idea, but in my case all the links must have the same delay, so
that is not a possibility.
It is a pity that NAM does not support this facility.
Best regards,
Javier

I' tried to add XY coordinates for wired nodes, but nam doesn't support this
facility.
Instead, I achieve the same result by setting the length of the wired links
via their delay

Hi ns-users,
I learnt that the previous problem can be solved by using 'orient'
method at the link definition. However, this solution is not enough when
defining more complex structures. The next figure shows 4 nodes standing
in the imaginary vertexes of a square, which are all of them connected to
a master node like it is shown in the next picture:
node(1,0)node(1,1)
(0,100) (100,100)__
\___\__
\___ \_
\___ master
_/(200,50)
_/ _/
/ /
(0,0) (0,100)
node(0,0) node(100,0)
--- What I would like to know is if it is possible (or not) to define the
geographic position of the nodes when the coordinates of them are known in
a wired scenario, or other ideas to solve the problem.

Asunto: ns/nam: respresentation problem when defining position-fixed nodes
Hi ns-users,
I would like to simulate a position-fixed wired network with 2 lines and 3
nodes per line, like it is shown above. The distance between the nodes
should be 100 units (for example), so the first node of the matrix will be
in (x=0,y=0) and the last node in (x=100, y=200).

When I do not define the links, the nodes are shown correctly in NAM
(without lines between them), but when I make some of the link definitions

[ns] Problem setting BO,SO pair in 802.15.4
Hi all, I'm using ns-allinone-2.31 package, that includes 802.15.4 implementation made by Zheng subsequently patched by Iyappan. If I set to 14 both Beacon Order (BO) and Superframe Order (SO) values of a generic device (not coordinator), ns returns this error message:  unable to start as a device: active channel scan failed - This happens using scss methods and independently from the values assumed by others flags, like assoPermit or isFFD. Instead if I set BO=14 and SO=13, all works well. Am i making some mistakes or the legal pair (BO=14,SO=14) is not admitted in current implementation of 802.15.4? I'm looking forward to receive your prompt reply. Best regards Busanelli Stefano

[ns] Defining diferent multicast groups
Hi ns-users, I have two groups of nodes in my network, and I would like to define two multicast groups, one for each of them. The problem is that the traffic sources send the packets to ALL the nodes, and not only to the nodes within its group. For example, when source 'a' is transmitting to the group 'a' nodes, nodes of the group 'b' also receive the packets and reply with a 'prune' packet. After some time, nodes of the group 'b' do not receive packets from the source 'a', long time passes and they start receiving again. Anyone could give me a explanation of this, or knows the solution to the problem?? Many thanks in advance, Javier P.D. I have defined the multicast groups: set mproto DM set mrthandle [$ns_ mrtproto $mproto] set group_a [Node allocaddr] set group_b [Node allocaddr] I have defined each udp agent to its corresponding group: set udp_a [new Agent/UDP] $udp_a set dst_addr_ $group_a $udp_a set dst_port_ 0 $ns attach-agent $node(0) $udp_a I have attached each node to its corresponding group: $node($i) join-group $sink($i) $group_a __ LLama Gratis a cualquier PC del Mundo.

Re: [ns] ns/nam: respresentation problem when definingposition-fixed nodes (NEW question)
I have the same situation.
I solve it by using the same delay in the real simualtion, and use different

nodes
Hi ns-users,
I would like to simulate a position-fixed wired network with 2 lines and
3
nodes per line, like it is shown above. The distance between the nodes
should be 100 units (for example), so the first node of the matrix will
be
in (x=0,y=0) and the last node in (x=100, y=200).
node(1,1) node(1,2)node(1,3)
(100,0)__(100,100)(100,200)

Re: [ns] Problem setting BO,SO pair in 802.15.4
This reminds me about a bug in the original wpan implementation. Not sure if it is fixed in Iyappan patch as I am using ns-2.29. In the method: bool CsmaCA802_15_4::canProceed(double wtime, bool afterCCA) The following declaration exists: UINT_16 t_bPeriods,t_CAP; For large BO/SO values, UINT_16 is insufficient. I replaced it with UINT_32 and many problems with large BO/SO values were resolved. I used to get poor delivery ratio but now it is reasonable. I have no idea whether this has anything to do with your problem, but you might want to give it a try. There is a good chance it does. Make sure you update the type casts related to these two variables in this method, too. - Ahmad On Thu, 22 Mar 2007 10:47:37 +0100 Stefano Busanelli [EMAIL PROTECTED] wrote: Hi all, I'm using ns-allinone-2.31 package, that includes 802.15.4 implementation made by Zheng subsequently patched by Iyappan.

Instead if I set BO=14 and SO=13, all works well. Am i making some mistakes or the legal pair (BO=14,SO=14) is not admitted in current implementation of 802.15.4? I'm looking forward to receive your prompt reply. Best regards Busanelli Stefano

PRELIMINARY FHMIP upgraded for ns2.31
I've upgraded the Robert Hsieh's FHMIP code in order to compile in latest
ns2.31. I've also added to it the modifications detailed in appendix B of
this report (Handover Blackout Duration of Layer 3 Mobility Management
Schemes,
http://www.tkn.tu-berlin.de/publications/papers/Handover_Blackout_Duration_o
f_L3_Mobility_Management_Schemes1.pdf)
However, when I've tried the HMIP part of the extension (the MAP), the
simulation continues to crash in a failed assert; however, I've tried the
FMIP part alone, and it seems to run OK.
__Please note that I did not test this extension any further__
To install:
first, install NS-allinone-2.31;
then, uncompress and apply the patch
(http://tagus.inesc-id.pt/~pestrela/ns2/files/ns2.31_fhmip.patch.gz)
, then reconfigure and recompile ns2 again.
The original FHMIP example is located in /tcl/ex/fhmip

Re: [ns] The Exact Value Between Two Subseqent RTS Packets
Hamid, I assume by value you are talking about time between two packets. There is no specific time that is between two packets. Once the first packet is sent, the receiver waits for a timeout period. If it does not receive a CTS it increments a backoff counter and selects a random time frame to wait to try sending another RTS. This value is not fixed. The boundaries for which the random backoff time is chosen are dependant on the minimum contention window and how many times a node has failed accessing the channel.

[ns] queue block and unblock help (can anyone summarize a correct step to do this?)
Hello ns users, From the past few years, there are a lot of questions regarding to make block and unblock queue dynamically by set blocked_ variable at queue.cc. I wonder if there is anyone who can make this work? If yes, could you please draw the step to do? If not, I wonder if anyone can come up with some trick to simulate a block and unblock queue? One thing I am curious is that if it's because NS2 is a event driven so the queue can't be drained if there is no packet coming in to that queue to activate deque().
