in my protocol code, the addr_type is NS_AF_INET I define the port number as well here is my broadcast code :
http://nuraini.net/2007/09/16/unicast-and-broadcat-packet-on-ns2/ it works for me :) --------------- Nur Aini Rakhmawati Touch the sky, Down to the earth http://nuraini.net/ ----- Original Message ---- From: SS Mukaka <[EMAIL PROTECTED]> To: ns-users@ISI.EDU Sent: Tuesday, March 11, 2008 10:16:50 PM 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...
