Claim 0:
1. A distributed fiber optic sensor placement method comprising:
providing a fiber optic network comprising a set of nodes and a set of fiber optic links defined by G(V, E) where G is the fiber optic network, V is the set of nodes, and E is the set of links;
for each node in G(V, E),
determine all possible sensing routes (all_route_set) in the fiber optic network; and
determine the minimum set of sensing routes in the alt_route_set that fully cover all the links in the fiber optic network; and

determining sensor placement locations to be at either one of two ends of a sensing route that is within the minimum set of sensing routes in the alt_route_set that fully cover all the links in the fiber optic network; and
deploying the sensors at the sensor placement locations so determined.
