Hi all
I'm having a strange problem when I send a unicast packet in ns-2 (I use the
IEEE 802.15.4 module).
I've created a new packet type, and when the IP-destination field
(HDR_IP->daddr()) is set to broadcast, the packet is received by the nodes
correctly. However, when I set a specific address in the IP-destination field
(e.g. the node whose id is 4), this is received at physical layer (void
Phy802_15_4::recv(Packet *p, Handler *h)), but the fisrt if (if (sendUp(p) ==
0)) is satisfied and the packet is not send to upper layers. This is the reason
I said "strange".

wpan/p802_15_4phy.cc
--------------------------------------------------------
void Phy802_15_4::recv(Packet *p, Handler *h)
{
hdr_lrwpan* wph = HDR_LRWPAN(p);
hdr_cmn *ch = HDR_CMN(p);
FrameCtrl frmCtrl;
switch(ch->direction())
{
case hdr_cmn::DOWN:
/**/
break;
case hdr_cmn::UP:
default:
if (sendUp(p) == 0)
{
// The problem is that this if is satisfied and I don't know why
Packet::free(p);
return;
}
/**/
}
}

I appreciate all the help possible, thanks
