[ns] estimate the network conditions !

[levy david]

 Hello,

I need to do the following :
a node send a packet iff he estimate that his network conditions is good
(the node want to minimize the probability of packet loss), by good
conditions i mean no congestion, no collisions ...

my questions ;
1- among the following conditions which ones i should use and how (in ns2)
-awareness of the current queue size,
-packet statistics at the routing layer (received, forwarded, dropped),
-frame statistics at the link layer (received, retransmitted, dropped),
-current random backoff timer,
-and number of collisions,
2- how to combine them to make a final decision
3- is there any others conditions ?


I appreciate your replies.

Thanks,
LEVY David.
