Given a collection of terminals, each with a demand, a collection of concentrators, each with a capacity, and costs of connecting the terminals to the concentrators, the terminal ...
An instance of the generalized partial cover problem consists of a ground set U and a family of subsets S 2U . Each element e U is associated with a profit p(e), whereas each su...
We study the following problem: Given a tree G and a finite set of trees H, find a subset O of the edges of G such that G − O does not contain a subtree isomorphic to a tree f...
— The coverage and connectivity problem in sensor networks has received significant attention of the research community in the recent years. In this paper, we study this problem...

We consider the problem of broadcasting messages in a wireless energy-limited network so as to maximize network lifetime. An O(e log e) algorithm to construct a broadcast tree tha...
