Lossless Representation of Graphs using Distributions
We consider complete graphs with edge weights and/or node weights taking values in some set. In the first part of this paper, we show that a large number of graphs are completely...

A Supermodular Relaxation for Scheduling with Release Dates
We consider the schedulingproblem ofminimizinga weighted sum of completion times under release dates. We present a relaxation which is a supermodular polyhedron. We show that this ...

Energy Efficient Sleep Schedule for Achieving Minimum Latency in Query based Sensor Networks
Energy management in sensor networks is crucial to prolong the network lifetime. Though existing sleep scheduling algorithms save energy, they lead to a large increase in end-to-e...

Optimal Distributed Detection in Clustered Wireless Sensor Networks: The Weighted Median
− In a clustered, multi-hop sensor network, a large number of inexpensive, geographically-distributed sensor nodes each use their observations of the environment to make local ha...
