Fabian Castaño presented our work on WSN at ROADEF 2013

The problem presented here is "Maximizing network lifetime problem with connectivity constraint and QoS". Our method develops a matheuristics algorithm involving a column generation approach and two metaheuristics (GRASP and VNS). The combination has led to the best published results on a 100% QoS and achieved also the best results when the quality is lower.
