Subject: [manet] The way for a node to decide a link failure in DSR

Hello, all.

I am looking for the answer about "how does the IP or routing layer of a node decide that the link is broken or unavailable using DSR routing protocol? Is there any frame life time for the routing frame? so that if the time is expired, the frame is discarded or the destination address for the next hop is changed. Or, is the decision made based on the MAC failure? For example, in MAC of WLAN, the node tries 7 times and the frame is discarded. At this moment, what does IP layer do?

I will appreciate if anyone answer this question.

Thank you.
