Localization in underwater sensor networks: survey and challenges
In underwater sensor networks (UWSNs), determining the location of every sensor is important and the process of estimating the location of each node in a sensor network is known a...

An approximation algorithm for the fault tolerant metric facility location problem
We consider a fault tolerant version of the metric facility location problem in which every city, j, is required to be connected to rj facilities. We give the first non-trivial ap...

A 3-Approximation for Facility Location with Uniform Capacities
We consider the facility location problem where each facility can serve at most U clients. We analyze a local search algorithm for this problem which uses only the operations of ad...
