[ns] AODV cannot find a route using intermediate nodes
dear all, the attached file is a simple script in which i want use aodv routing protovol. but aodv cannot find a route since the destionation is not in the communication range of soruce. if any body can send packet while destination is not in the range of sender, please let me know. i need an advise for that. best, semra From: Semra YILMAZ Sent: Mon 31.03.2008 21:06 To: ns-users@ISI.EDU Subject: FW: Why AODV cannot find a route Dear all, I need the answer of my question below, asap. Please send your comments if you have any idea. Thanks, Semra From: Semra YILMAZ Sent: Sun 30.03.2008 21:45 To: ns-users@ISI.EDU Subject: Why AODV cannot find a route Dear all ns users, For the following topology i am using DSR and AODV routing protocols. I define two ftp traffic from node 0 to node 3 and node 1 to node 3. When i use DSR, there is no problem, packets are flowing in the routes 0-2-3 and 1-2-3. But when i use AODV, traffic cannot be started because node 3 (sink node) is not in the communication range of node 0 or node 1, AODV cannot find a route to node 3. When i close the node 3 to node 0 and node 1 (that is into the communication range), traffic is flowing in the route 0-3 and 1-3. It seems AODV cannot define a route with intermediate route. The aim of a routing protocol should be to find a route to destination. But I don't understand why such a situation occurs. If you know the problem for such a situation, please help me. Many thanks in advance. Semra O node 1 (50, 228) O O node 2 (200, 178)node 3 (300, 178) O node 0 (50, 128) ## Dikkat: Bu elektronik posta mesaji kisisel ve ozeldir.

[ns] Problem installing NIST mobility package in ns2.29
I'm trying to install the NIST mobility package in ns-2.29. I follow the following steps: Update compilation tools. Copy ns-2.29 folder from mobility package directory to the directory in which I have already installed ns-allinone-2.29. Update .bashrc form my directory to add ns to the PATH Execute make clean, ./configure, make into ns-allinone-2.29 directory. Then, I execute any wireless script from examples' folder, I open the trace, and it is different to the trace obtained in the simulation with the original ns-allinone-2.29. There are a lot of packets dropped, and only a litte amount of received packets. For example, I obtain someethig like this: s -t 210.185948154 -Hs 0 -Hd -2 -Ni 0 ... Ssb 212.67937 _0_ dropped 0 - 2 d -t 212.679371380 -Hs 0 -Hd -2 -Ni 0 ... And at the end of the trace only dropped packets d -t 400.0 -Hs 0 -Hd -2 -Ni 0 -Nx 89.66 -Ny 283.49 -Nz 0.00 -Ne -1.00 -Nl RTR -Nw END -Ma 0 -Md 0 -Ms 0 -Mt 0 -Is 0.0 -Id 2.0 -It cbr -Il 532 -If 0 -Ii 46820 -Iv 32 -Pn cbr -Pi 68 -Pf 0 -Po 3 Any information regarding this will be really appreciated. Thanks in advance. - - Enviado desde Correo Yahoo! Disfruta de una bandeja de entrada más inteligente..

[ns] Rx Threshold calculation when using Ricean fading model
Hi all, I have a simple question. I am running a scenarion consisting of a 5x5 grid of static nodes using AODV protocol. I am using Ricean fading model instead of the TwoRayGround. I have calculated the RxThreshold and the CSThresold using the threshold.o utility in ns-2 by setting the propagation parameter as the TwoRayGround (I have asked about this and the answer is that I must use the TwoRagGround to calaculate the threshold even though I am using ricean). I have set the transmission range equal to 250 m, what I have realized that broadcasted packets can be heard at a distance greater than 250 (about 370 m) and they are received successfully but this would not happen when I am using TwoRwyGround. This is must not happen right? no successful transmission must happen after 250m. but where is the error? is it in calculating the RXThreshold when using the Ricean? please help me. thanks, gaby - You rock.
