Optimizing data replication for expanding ring-based queries in wireless sensor networks
We consider the problem of optimizing the number of replicas for event information in wireless sensor networks, when queries are disseminated using expanding rings. We obtain clos...

Improved bounds for the unsplittable flow problem
In this paper we consider the unsplittable flow problem (UFP): given a directed or undirected network G = (V, E) with edge capacities and a set of terminal pairs (or requests) wit...
