Message-optimal connected dominating sets in mobile ad hoc networks
A connected dominating set (CDS) for a graph G(V, E) is a subset V of V , such that each node in V - V is adjacent to some node in V , and V induces a connected subgraph. A CDS ha...

A Polynomial-Time Approximation Algorithm for Weighted Sum-Rate Maximization in UWB Networks
— Scheduling in an ad hoc wireless network suffers from the non-convexity of the cost function, caused by the interference between communication links. In previous optimization t...

Algorithms for Identifying Rigid Subsystems in Geometric Constraint Systems
The structural rigidity property, a generalization of Laman’s theorem which characterizes rigid bar frameworks in 2D, is generally considered a good approximation of rigidity in...
