Re: [ns] HOW TO GET THE POSITION OF NODE IN C++ CODE ??
Hi, Try using this line: Node* node =0; node = Node::get_node_by_address(node_ID); MobileNode* nd = (MobileNode*)node; nd-getLoc(sx,sy,sz); I think u have to include “#include god.h”, hope this helps...

[ns] Software validation
Hi all, I am trying to validate my simulation using coefficient of variation principles but when I calculate the confidence interval CI, most of the results I get by changing the seed are out from that interval. Are my results wrong?? Need all the result to be within that interval??? Please a hint guys, a line answer is suffficient. Thanks a lot,
[ns] port_dmux ???
Hi everybody, Can anybody tell me what this line of code does. It is part of DSDV.cc file. I have to know this in order to progress my work, so please do reply. port_dmux_- recv ( p, (Handler*) 0 ); Thank you very much,
[ns] cbrp - error when calling class $cls: $args $...
Hi all,
I am developping a cbrp code for ns2.34 and I thought that I did everything
good
when it compiled good, but when I try to use it I am facing the below error. If
anybody has an idea about this error, please do reply because I have no much
time left to do this!!! I have been trying to solve it but no matter what I do,
I still get the exact same error. It is something that has to do when the nodes
are being created and routing agents attached to them. I guessed to look at
ns-lib.tcl but I tried a lot of things unsuccessfully. I would be most happy
to share this protocol with you when it is finished.
Thanks soo much,

I found some posting regarding this error and said to apply a certain patch
file
but it didnt work. Please guys I need to use this version, or please if
anybody
knows a version that could be installed without any problem that is almost the
same as Allinone-ns 2.1b5 please let me know. I already have the
Allinone=ns2.34
but the software is not working on this version. When I tried to apply it on
ns2.34 I was getting a lot of errors, so I need to install Allinone-ns 2.1b5.
Thank you sooo much,

[ns] signal strenght
I am trying to modify aodv.cc broadcast mechanism so a packet is only broadcasted if the signal strenght between the transmitting and the recieving node is greater than a certain value. I found out that tworayground.cc file calculate the signal strenght between two nodes using the function below: double TwoRayGround : : Pr (PacketStamp *t, PacketStamp *r, WirelessPhy *ifp). Can anybody tell me what are these variables PacketStamp *t, PacketStamp *r, WirelessPhy *ifp and how can I call this function from aodv.cc?? It is soo urgetn and important guys please give me some hints at least to where to look into it... Thanks
[ns] Aget or roting protocol is handling this???
Hi all, I have an agent that rebroadcast to all its neigbours when it recieve a packet that has a Broadcast address as destination address. Moreover, I am using a probability routing protocl, that means when receiving a broadcast pkt, it rebroadcast with some probability. So, I am wondering if a recieved broadcast pkt will be handled by the agent or the routing protocol. In other words, will the packet be rebroadcasted with some probability, as the routing protocol functions, or it will be normal broadcast as the agent functions?? Please guys, it is soo important. Thanks,
[ns] cbrgen command
Hi all, I am generating different traffic scenario files by changing the number of nodes and I am wondering if it is better to change the number of multiple connections as well. Logically, I think I should because as the number of nodes increases, there should be more multiple connections. Am I right?? Please anybody who has done some kind of comparison tells me which way is it. Thanks in advance,

[ns] Broadcasting in ad hoc nets
Hi all, I have an agent that broadcast to all neighbours, and I am using a CBRP (Cluster-Based Routing Protocol). So, can anybody tells me what really happens in the network when this agent broadcasts a packet. Will it follow the clustering broadcast or normal broadcasting. In other words, is the agent working on top of the cluster based routing protocol??? I am new to ns2 but I think that the origenating node will perform normal broadcasting and then all others will follow the cluster based as the routing protocol is cluster based. Am I right? Please guy give me a hint. Thanks a lot,
[ns] Number of neighbours
Hi all,
How can I know the number of neighbours a node has before sending a packet. I
am
using the Agent below. When recieving, the node brodcast the packet with a
probability. I need to know the number of neighbours to make that probability
dynamic. In other words, when recieving a packet, the probability of
rebroadcasting will be higher if there will be fewer neighbours.
Thanks a lot.

Hi, I came across you broadcasting agent of 2001: http://www.isi.edu/nsnam/archive/ns-users/webarch/2001/msg05889.html Can anybody give me a hand to implement it and use it. I am using ns-allinone-2.34. I really need to learn how it works and how to use it. Thanks in advance.
[ns] Broacasting in ad hoc netwroks
Hi, I am trying to make a comparison between three broadcast techniques, the normal flooding, clustering and the enhanced clustering, in ad hoc networks. I learned how to build up a simple ad hoc network, but I still dont know how to simply broadcast. Moreover, how can I change the broadcast technique??? Do I have to do some C++ coding first?? If so, Can you please tell me the steps for implementing a broadcast technique in MANETs. Thank you for your time.
