1.757 and 1.267-Approximation Algorithms for the Network and and Rectilinear Steiner Tree Problems

The Steiner tree problem requires to find a shortest tree connection
a given set of terminal points in a metric space. We suggest a better
and fast heuristic for the Steiner problem in graphs and in
rectilinear plane. This heuristic finds a Steiner tree at ... more >>>

Efficient Communication Establishment in Extremely Unreliable Large Networks

We consider here a large network of $n$ nodes which supports
only the following unreliable basic communication primitive:
when a node requests communication then this request
{\em may fail}, independently of other requests, with probability
$f<1$. Even if it succeeds, the request is answered by returning
a stable link to ... more >>>

Online Capacity Maximization in Wireless Networks

In this paper we study a dynamic version of capacity maximization in the physical model of wireless communication. In our model, requests for connections between pairs of points in Euclidean space of constant dimension $d$ arrive iteratively over time. When a new request arrives, an online algorithm needs to decide ... more >>>
