[ns] Fw:Re: How to shut down a mobile node

[realoneone]

Hi oudidi, please check the following lines:

inline void
Mac802_11::transmit(Packet *p, double timeout)
{
tx_active_ = 1;
int nid = netif_->node()->nodeid();
double now = Scheduler::instance().clock();
  
if (nid == my_nid && now >= my_time_start && now < my_time_end) {
mhSend_.start(timeout);
return;
}

//... original code below
}

void
Mac802_11::recv(Packet *p, Handler *h)
{
int nid = netif_->node()->nodeid();
double now = Scheduler::instance().clock();

if (nid == my_nid && now >= my_time_start && now < my_time_end) {
struct hdr_cmn *hdr = HDR_CMN(p);
hdr->error() = 1;
}

//... original code below
}

Hi there,

Though I had problems by just using "on/off" command of the mobile nodes, I finally used a tricky way to "shut down" some nodes at certain time:

In mac/mac-802_11.cc, I added a few lines in the beginning of transmit() and recv(), which stop transmitting/receiving the packet depending on the clock time and the id of the node which is calling this function.

Though I have to re-make ns2, it does works fine for me.

Hope it helps.

Ryan
