Slight change from previous email!
Hi again and thanks, I now have a clearer picture of the problem.
But PLease can I have your advice, I really need to get this working .
I've followed the steps very closely, and have narrowed down the location of
problem to instruction 7.
"
mac/wireless-phy.h:
change
enum ChannelStatus {IDLE, RECV, SEND};
to
enum ChannelStatus {IDLE, RECVING, SENDING};
mac/wireless-phy.cc:
replace all occurences of RECV and SEND (by RECVING and SENDING).
"
After successfully doing ./configure
successfully doing Make Clean
successfully doing Make Depend
I Run 'Make' and I get the error
mac/wireless-phy.cc: In wireless function 'virtual void
WirelessPhy::sendDown(Packet*)':
mac/wireless-phy.cc:302: error: 'class Channel' has no member named
'RECVING'
make: *** [mac/wireless-phy.o] Error 1
If I replace the RECVING with RECV I get the similar error:
mac/wireless-phy.cc: In wireless function 'virtual void
WirelessPhy::sendDown(Packet*)':
mac/wireless-phy.cc:302: error: 'class Channel' has no member named 'RECV'
make: *** [mac/wireless-phy.o] Error 1
There are no solutions to this on the web
Here is the sendDown method
WirelessPhy::sendDown(Packet *p)
{
/*
* Sanity Check
*/
assert(initialized());
if (em()) {
//node is off here...
if (Is_node_on() != true ) {
Packet::free(p);
return;
}
if(Is_node_on() == true && Is_sleeping() == true){
em()-> DecrSleepEnergy(NOW-update_energy_time_,
P_sleep_);
update_energy_time_ = NOW;
}
}
/*
* Decrease node's energy
*/
if(em()) {
if (em()->energy() > 0) {
double txtime = hdr_cmn::access(p)->txtime();
double start_time = MAX(channel_idle_time_, NOW);
double end_time = MAX(channel_idle_time_, NOW+txtime);
double actual_txtime = end_time-start_time;
if (start_time > update_energy_time_) {
em()->DecrIdleEnergy(start_time -
update_energy_time_, P_idle_);
update_energy_time_ = start_time;
}
/* It turns out that MAC sends packet even though, it's
receiving some packets.
if (txtime-actual_txtime > 0.000001) {
fprintf(stderr,"Something may be wrong at MAC\n");
fprintf(stderr,"act_tx = %lf, tx = %lf\n", actual_txtime, txtime);
}
*/
// Sanity check
double temp = MAX(NOW,last_send_time_);
/*
if (NOW < last_send_time_) {
fprintf(stderr,"Argggg !! Overlapping transmission. NOW %lf last %lf
temp %lf\n", NOW, last_send_time_, temp);
}
*/
double begin_adjust_time = MIN(channel_idle_time_, temp);
double finish_adjust_time = MIN(channel_idle_time_, NOW+txtime);
double gap_adjust_time = finish_adjust_time - begin_adjust_time;
if (gap_adjust_time < 0.0) {
fprintf(stderr,"What the heck ! negative gap time.\n");
}
if ((gap_adjust_time > 0.0) && (status_ == RECV)) {
em()->DecrTxEnergy(gap_adjust_time,
Pt_consume_-Pr_consume_);
}
em()->DecrTxEnergy(actual_txtime,Pt_consume_);
// if (end_time > channel_idle_time_) {
// status_ = SENDING;
// }
//
status_ = IDLE;
last_send_time_ = NOW+txtime;
channel_idle_time_ = end_time;
update_energy_time_ = end_time;
if (em()->energy() <= 0) {
em()->setenergy(0);
((MobileNode*)node())->log_energy(0);
}
} else {
// log node energy
if (em()->energy() > 0) {
((MobileNode *)node_)->log_energy(1);
}
//
Packet::free(p);
return;
}
}
/*
* Stamp the packet with the interface arguments
*/
p->txinfo_.stamp((MobileNode*)node(), ant_->copy(), Pt_, lambda_);
// Send the packet
channel_->RECV(p, this);
}
Sincere Thanks and Regards,
