[ns] can't send pkt (unicast/broadcast) - MANET ns2.30

[levy david]

Hello ns-suers,

 i can't send unicast or broadcast packets, I try several solutions, but no
one works!

1- the code for unicast  (sendUnicast(destination))

    Packet* pkt = allocpkt();
    hdr_cmn* hdrcmn = hdr_cmn::access(pkt);
    hdr_ip* iphdr   = hdr_ip::access(pkt);
    hdr_monitor* hdrret = hdr_monitor::access(pktret);
    hdrret->ret = 1;
    hdrcmn->next_hop_ = destination;
    hdrcmn->prev_hop_ = this->addr();
    hdrcmn->direction() = hdr_cmn::DOWN;
    hdrcmn->ptype() = PT_MONITOR;
    hdrcmn->addr_type() = NS_AF_INET;   //NS_AF_INET; // NS_AF_ILINK;

    // setting the ip header
    iphdr->saddr() = this->addr();
    iphdr->sport() = 100; // 1-254
    iphdr->daddr() = destination;
    iphdr->dport() = 100; // 1-254
    iphdr->ttl() = 32;
    fprintf(stderr, "%d send request to %d \n",this->addr(),destination);

    // send
    Scheduler::instance().schedule(ll, pkt, 0.0);

2- for broadcast i use the following code

    Packet* pkt = allocpkt();
    hdr_gc* hdr = hdr_gc::access(pkt);
    hdr->ret = 0;
    hdr_cmn* hdrcmn = hdr_cmn::access(pkt);
    hdr_ip* iphdr   = hdr_ip::access(pkt);
    hdrcmn->next_hop_ = IP_BROADCAST;
    hdrcmn->prev_hop_ = this->addr();
    hdrcmn->direction() = hdr_cmn::DOWN;
    hdrcmn->ptype() = PT_GC;
    hdrcmn->addr_type() = NS_AF_INET;  //NS_AF_NONE NS_AF_ILINK;

    // setting the ip header
    iphdr->saddr() = this->addr();
    iphdr->sport() = 101; // 1-254
    iphdr->daddr() = IP_BROADCAST;
    iphdr->dport() = 101; // 1-254
    iphdr->ttl() = 1;
    fprintf(stderr, "%d send bcats\n",this->addr());

    // send
    Scheduler::instance().schedule(ll, pkt, 0.0); // _target !
---------------------
i use the TclObject::lookup to get the ll.


Thanks
