propogation model -- ns+CMU

[Deepesh Chouhan <chouhan@usc.edu>]

hi,

When a packet comes in, net-if stamps the packet with recv.
interfaces properties and then invokes prop model. This in
turn calculates power with which the packet was recd. USing
this net-if calculates successful reception of packet.


My problem is that i want to repeat the entire proc. for
"ALREADY" recd. packets but with diff. stamps.
For e.g. if prev. the net-if prop. range was 'd' i wanna
check if this packet could be recd. if the range was 'd/2'.

additionally, i don't want this check to be done on all
packets. 

Can i repeat the above mentioned proc. from Link layer ?
