Mobile backbone networks --: construction and maintenance
We study a novel hierarchical wireless networking approach in which some of the nodes are more capable than others. In such networks, the more capable nodes can serve as Mobile Ba...

A tree-based genetic algorithm for building rectilinear Steiner arborescences
A rectilinear Steiner arborescence (RSA) is a tree, whose nodes include a prescribed set of points, termed the vertices, in the first quadrant of the Cartesian plane, and whose tr...

Deterministic Sampling Algorithms for Network Design
For several NP-hard network design problems, the best known approximation algorithms are remarkably simple randomized algorithms called Sample-Augment algorithms in [11]. The algor...

Bounded-skew clock and Steiner routing under Elmore delay
: We study the minimum-cost bounded-skew routing tree problem under the Elmore delay model. We presenttwo approachesto construct bounded-skew routing trees: (i) the Boundary Mergin...
