send message is limited to number of nodes?

[Gisane Michelon]

I am trying send msg (using OLSR  in inetmanet) to all nodes of the routing table, but  when has more that 12 nodes only send to first twelve. Has a limit of number of nodes that can be message?

for (int i=0; i< rota->getNumRoutes()-1 ;i++)

  {   IPv4Route *e1 = rota->getRoute(i);

      InterfaceEntry *interfacePtr = e1->getInterface();

      Origem =hostIndexByAddress(interfacePtr->ipv4Data()->getIPAddress());

       IPvXAddress *destino =addressByHostIndex(destino1);

     requestData1(*destAddress, *destino, dataPart);

   }

void UDPBasicBurst::requestData1(IPvXAddress origem, IPvXAddress destino, string dataPart)

{   int noOrigem= hostIndexByAddress(origem);

    stringstream ss1;

    ss1 << noOrigem;

    string str1 = ss1.str();

    char *msgName = (char*)("data_request"+dataPart + str1 ).c_str();

    cPacket *pk3 = new cPacket(msgName);

    socket.sendTo(pk3,destino, appPort);

}

example routing table OLSR

-- Routing table --

145.236.0.6      255.255.255.255  145.236.0.17     wlan0 (145.236.0.40) 3

no, there isn't a limit
it is possible that the nodes could be out of the coverage area.
In the case that the nodes are in coverage area, exist also the possibility that the routing tables hasn't been completely built, OLSR needs some time to construct the routes.

thanks Alfonso, but the table OLSR is full and the nodes are coverage area.

I did tests and realized that the node send the message to all nodes, but only first twelve nodes receive.

In the table below,  the node 145.236.0.7 send message to all nodes of your table, but only nodes to node 20 receive and the table is full and the nodes are coverage area.

Does Olsr never build the whole table?

 

OLSR takes some time to construct the tables

[Gisane Michelon]

but according with the table node 145.236.0.7 that I posted in the last e-mail, OLSR is build  the whole table, but only  the first nodes that receive the message sent by node 145.236.0.7, and this always occurs (not only node 145.236.0.7)

[Alfonso Ariza Quintana]

You can see that there are nodes that aren’t in the table

OLSR needs some time to find the paths to all nodes

[Gisane Michelon]

I found the error, I increased frameCapacity and maxQueueSize and work.

thanks 

[Adriana V R]

I have the same problem. Where did change the frameCapacity and maxQueueSize?

Thanks, it's working now!

a hint I found that is really handy to know all options that omnet++ can give you in the configuration file press on ctrl+space

nameofsimulation.(ctrl+space)

and so on till you know all the possible options

also to open the .cc or .h file of any module that is used in .Ned or in ini just (press ctrl and click on it)
