Maximum lifetime data sensing and extraction in energy constrained networked sensor systems
We focus on data gathering problems in energy constrained networked sensor systems. The system operates in rounds where a subset of the sensors generate a certain number of data p...

Approximability and Nonapproximability Results for Minimizing Total Flow Time on a Single Machine
We consider the problem of scheduling n jobs that are released over time on a single machine in order to minimize the total ow time. This problem is well-known to be NPcomplete, a...

Design closure driven delay relaxation based on convex cost network flow
Design closure becomes hard to achieve at physical layout stage due to the emergence of long global interconnects. Consequently, interconnect planning needs to be integrated in hi...

Adjacent 2-Route Flow Approach for Restorable Dynamic Routing in MPLS Networks
In this paper we focus on issues of restorable dynamic routing in MPLS networks. We assume that the considered MPLS network must provide reliable service including restorable rout...
