Optimal Routing in Binomial Graph Networks
A circulant graph with n nodes and jumps j1, j2, ..., jm is a graph in which each node i, 0 ≤ i ≤ n−1, is adjacent to all the vertices i±jk mod n, where 1 ≤ k ≤ m. A bi...

On Channel-Discontinuity-Constraint Routing in Wireless Networks
Multi-channel wireless networks are increasingly being employed as infrastructure networks, e.g. in metro areas. Nodes in these networks frequently employ directional antennas to ...

Approximating Optimal Binary Decision Trees
Abstract. We give a (ln n + 1)-approximation for the decision tree (DT) problem. An instance of DT is a set of m binary tests T = (T1, . . . , Tm) and a set of n items X = (X1, . ....

Approximation of Pathwidth of Outerplanar Graphs
There exists a polynomial time algorithm to compute the pathwidth of outerplanar graphs [3], but the large exponent makes this algorithm impractical. In this paper, we give an alg...

Independent Directed Acyclic Graphs for Resilient Multipath Routing
—In order to achieve resilient multipath routing we introduce the concept of Independent Directed Acyclic Graphs (IDAGs) in this study. Link-independent (Node-independent) DAGs s...
