1-link shortest paths in weighted regions
We illustrate the Link Solver software for computing 1-link shortest paths in weighted regions. The Link Solver implements a prune-and-search method that can be used to approximat...

Distributed Sleep Scheduling in Wireless Sensor Networks via Fractional Domatic Partitioning
We consider setting up sleep scheduling in sensor networks. We formulate the problem as an instance of the fractional domatic partition problem and obtain a distributed approximati...
