Re: [manet] DSR and Dijkstra's algorithm

[Noah.H.Miller@Dartmouth.EDU (Noah H. Miller)]

Hello,

According to DSR Internet Draft 7, there is a maximum number of retransmissions of a Request (suggested: 16) and a maximum period for those retransmissions (10 seconds) (see pages 47 and 67).  DSR has similar variables for source routed pack
ets.

A similar problem to the one you raised is the lack of a blacklist for Requests to destinations that cannot be reached (for instance, destinations on the other side of a partition).  A node is allowed to restart Route Discovery as soon as the 
maximum period for a Request is up, with the time between Requests reset to the initial, small period.

Hi All,I have another doubt regarding DSR. I read from thelatest
dr aft that for retransmission of route requestit uses binary backoff
algorithm. However is there anylimit on the numbre of retries ? I am
not sure evenwhether Network layer should handle max retries
orapplicaiton layer should handle this ?Thanks and Regards,--Sameer
