Hi all,

I am using multiple sinks with high density network in my Tcl code. That is
I am using 500 devices(sensor nodes) and 4 sink nodes which are deployed
randomly. I want to create traffic between sink and devices. My concept is
"the devices should select sink node *based on transmission energy or
area*and send packets to corresponding sink node".

How to achieve that? I googled but i couldnt find answer.
**
for {set val(x) 0} {$val(x) < 25} {incr val(x)} {
for {set val(y) 0} {$val(y) < 25} {incr val(y)} {
for {set i 1} {$i < $val(nn)} {incr i} {
   ftptraffic $i 0 $appTime(1)
}
}
}
I used like this in my code.
I am getting error as follows:

num_nodes is set 504
INITIALIZE THE LIST xListHead

Traffic: ftp
Acknowledgement for data: on
*terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc*

what it means?

Please anyone reply me.

Thank you.
