Route Maintenance in DSR.

(1) for all    do

(2)  start

(3)  if upstream node detects   then

(4)   remaining nodes of path search alternative route in RC

(5)   if found alternative   then

(6)    send data to this

(7)   else

(8)     starts route re-discovery

(9)     piggy-backs with new

(10)  end if

(11) else

(12)  upstream nodes receive feed-back from downstream nodes
