Hello, I was trying to use AODV for a wireless scenario with mobiltiy with TDMA as my MAC in the first case and 802.11 as my MAC in the second case.The scenario is 3 nodes (node 0,1,2 with 1 in between 0 and 2).
I have the following questions. 1) When TDMA is the MAC and when 2 moves out of range of 1 there is no RERR messages as we expect in theory. Instead node 1 forwards the data and there is no trace of what happens to it after that. 2) When 802.11 is the MAC we get RERR messages which are triggered by MAC retransmission failures but the CTS from node to gets dropped and the error flag says STA which means Invalid MAC state.I don't understand what that means. 3) In theory, RERR messages are triggered by HELLO packets (exchanged periodically between neighbors) as well as MAC level retransmissions.But in ns-2 the HELLO packet triggered RERR doesn't seem to work. Am I doing something wrong or is there a bug? I appreciate your replies Thanks, Sarvesh Best Jokes, Best Friends, Best Food and more. Go to http://in.promos.yahoo.com/groups/bestofyahoo/
