Now let`s add a new MAC protocol.
1) Put your new MAC program files (newMAC.cc and newMAC.h) to ns-2.34/mac
2) Modify common/packet.h
#define HDR_NEWMAC(p) ((hdr_newmac *)hdr_mac::access(p)) // add newmac here
Find "enum packet_t{}" and add PT_NEWMAC. Notice that it must be added before PT_NTYPE.
Find "class p_info{}" and add name_[PT_NEWMAC] = "newmac". It must be before name_[PT_NTYPE] = "undefined".
3) Modify tcl/lib/ns-default.tcl
Add Mac/NEWMAC set syncFlag_ 1
Add Mac/NEWMAC set selfConfigFlag_ 1
Add Mac/NEWMAC set dutyCycle_ 10
……
In the later line,
Add Mac/NEWMAC set syncFlag_ 0
4) Modify tcl/lib/ns-packet.tcl
Find "foreach prot{}" and add NEWmac
5) Modify ns2.34/Makefile
Add mac/newmac.o \
6) Now a new MAC protocol has been added to NS2. We will modify some trace files in the next.
7) Modify trace/cmu-trace.h
Add void format_newmac(Packet *p, int offset);
8) Modify trace/cmu-trace.cc
Find "void CMUTrace::format_mac_common(Packet *p, const char *why, int offset)"
struct hdr_cmn *ch = HDR_CMN(p);
struct hdr_ip *ih = HDR_IP(p);
struct hdr_mac802_11 *mh;
struct hdr_smac *sh;
struct hdr_newmac *ph; // add newmac pointer
char mactype[SMALL_LEN];
strcpy(mactype, Simulator::instance().macType());
if (strcmp (mactype, "Mac/SMAC") == 0)
sh = HDR_SMAC(p);
else if (strcmp (mactype,"Mac/NEWMAC") == 0)
ph = HDR_LMAC(p);
else
mh = HDR_MAC802_11(p);
……
if (strcmp (mactype, "Mac/SMAC") == 0) {
format_smac(p, offset);
}
else if (strcmp (mactype, "Mac/NEWMAC") == 0) {
format_newmac(p, offset);
}
else {
format_mac(p, offset);
}
return;
Find "if(newtrace)"
offset = strlen(pt_->buffer());
if (strcmp(mactype, "Mac/SMAC") == 0) {
format_smac(p, offset);
}
else if (strcmp(mactype, "Mac/NEWMAC") == 0) {
format_newmac(p, offset);
}
else {
format_mac(p, offset);
}
……
(ch->ptype() == PT_SMAC) ? (
(sh->type == RTS_PKT) ? "RTS" :
(sh->type == CTS_PKT) ? "CTS" :
(sh->type == ACK_PKT) ? "ACK" :
(sh->type == SYNC_PKT) ? "SYNC" :
"UNKN") :
(ch->ptype() == PT_NEWMAC) ? (
(ph->type == RTS_PKT) ? "RTS" :
(ph->type == CTS_PKT) ? "CTS" :
(ph->type == ACK_PKT) ? "ACK" :
(ph->type == SYNC_PKT) ? "SYNC" :
"UNKN") :
packet_info.name(ch->ptype())),
ch->size());
……
if (strncmp (mactype, "Mac/SMAC", 8) == 0) {
format_smac(p, offset);
}
else if (strncmp (mactype, "Mac/NEWMAC", 8) == 0) {
format_newmac(p, offset);
}
else {
format_mac(p, offset);
}
……
Add a new function
void CMUTrace::format_newmac(Packet *p, int offset)
{
struct hdr_newmac *ph = HDR_NEWMAC(p);
sprintf(pt_->buffer() + offset,
" [%.2f %d %d] ",
ph->duration,
ph->dstAddr,
ph->srcAddr);
}
9) Find "void CMUTrace::format(Packet* p, const char *why)"
Add
switch(ch->ptype()) {
case PT_MAC:
case PT_SMAC:
case PT_NEWMAC:
break;
case PT_ARP:
format_arp(p, offset);
break;
10) Finally, add the header files #include
