Hi All,
I have a question regarding the energy model and wireless-phy in ns-2.29.
In the function WirelessPhy::sendDown(Packet *p) we see the following code:
v1.23
http://nsnam.cvs.sourceforge.net/nsnam/ns-2/mac/wireless-phy.cc?revision=1.23&view=markup
"
207 if (em()) {
208 //node is off here...
209 if (Is_node_on() != true ) {
210 Packet::free(p);
211 return;
212 }
213 if(Is_node_on() == true && Is_sleeping() == true){
214 em()-> DecrSleepEnergy(NOW-update_energy_time_,
215 P_sleep_);
216 update_energy_time_ = NOW;
217 218 }
"
v1.22
http://nsnam.cvs.sourceforge.net/nsnam/ns-2/mac/wireless-phy.cc?revision=1.22&view=markup
"
190 if (em())
191 if ((em()->node_on() != true) || (em()->sleep())) {
192 Packet::free(p);
193 return;
194 }
"
It seems rational to me that we should also "free" the packet if the
node is on and sleeping (as in v1.22).
According to v 1.23-v1.25, the wireless-phy can send a packet down, even
if it's sleeping?
What is the rationale?
Best regards,
Pieter
