We consider the problem of deploying or repairing a sensor network to
guarantee a specified level of multi-path connectivity (k-connectivity)
between all nodes. Such a guarantee simultaneously provides fault tolerance
against node failures and high overall network capacity (by the max-flow
min-cut theorem). We design and analyze the first algorithms that place an
almost-minimum number of additional sensors to augment an existing network
into a k-connected network, for any desired parameter k.
Our algorithms have provable guarantees on the quality of the solution.
Specifically, we prove that the number of additional sensors is within a
constant factor of the absolute minimum, for any fixed k. We have
implemented greedy and distributed versions of this algorithm, and demonstrate
in simulation that they produce high-quality placements for the additional
