How can we avoid this ? In my protocol, max of the RREP packets are dropping. I think this is due to mac layer congestion. I am using the four way neighbor detection mechanism which is proposed to avoid rushing attack by Adrian Perigg at el. in the paper "Rushing attacks and Defence in Wireless Ad Hoc Routing Protocols" (I have attached this paper). Due to that packet delivery ratio is very less. How can we correct this... any suggestion ? Thanks in advance... Anupama A
