[ns] Nodes not receiving broadcast message

2008-03-13 Thread Sidney Doria

Hi Mukaka and all,

 try to add this

 ch-direction()  = hdr_cmn::DOWN;
 ch-next_hop() = MAC_BROADCAST;

   in my protocol code, the addr_type is NS_AF_INET
   I define the port number as well
   here is my broadcast code :

   it works for me :)

   Subject: [ns] Nodes not receiving broadcast message
 
 
   I want to send a broadcast message to neighbours I'm having a problem
   because the nodes are not receiving the message if I put ih-daddr() =
   IP_BROADCAST;
   I have tested it by putting ih-daddr() = 1; and it worked... ie. node 1 was
   able to receive the message.. Below is my code for sending and also for
   receiving
 
   void ReQuest::sendREQUEST()
   {
 
Packet* p = Packet::alloc();
struct hdr_cmn* ch = HDR_CMN(p);
struct hdr_ip* ih = HDR_IP(p);
struct hdr_MyPacket* ah = HDR_MyPacket(p);
ch-size() = IP_HDR_LEN + ah-size();
ch-addr_type() = NS_AF_NONE;
 
ih-daddr() = IP_BROADCAST;
ih-saddr() = index;
ah-MyPacket_type = ReQ;
Scheduler::instance().schedule(target_, p, 0.0);
   }
 
   My receive function is as follows:
 
   void ReQuest::recv(Packet* p, Handler*)
   {
struct hdr_cmn* ch = HDR_CMN(p);
struct hdr_ip* ih = HDR_IP(p);
struct hdr_MyPacket* ah = HDR_MyPacket(p);
nsaddr_t src = ih-saddr();
printf(Node %d receiving data packet from %d \n, index, src);
 
   // processing packet
   }
 
   like i said,  nodes can only receive messages if i put the IP address of the
   receipient but when i use IP_BROADCAST, nothing is received...
 
   Thank you in advance
