In recent years, Software Defined Networking (SDN) has emerged as a pivotal element not
only in data-centers and wide-area networks, but also in next generation networking …

Emerging network services and subsequent growth in the networking infrastructure have
gained tremendous momentum in recent years. Application performance requiring rapid real …

Controller placement is a key problem in software defined networks (SDNs). Previously, the
solution to this problem only focused on propagation latency but ignored the load of …

Abstract Software Defined Networking (SDN) decouples control and data planes. The
separation arises a problem known as the controller placement, ie, how many and where …

The controller placement problem (CPP) is one of the main issues that need to be
addressed in the context of Software Defined Networking (SDN), especially when different …

The vertex p-center problem consists in selecting p centers among a finite set of candidates
and assigning a set of clients to them, with the aim of minimizing the maximum dissimilarity …

This paper considers a bi-level hazmat transportation network design problem in which
hazmat shipments have to be transported over a road network between specified origin …

The spatial optimization method between combinatorial optimization problems and GIS has
many geographical applications. The p-center problem is a classic NP-hard location …

A p-center is a minimax solution that consists in a set of p points that minimizes the
maximum distance between a demand point and a closest point belonging to that set. We …

Software Defined Network (SDN) is an emerging network paradigm which provides a
centralized view of the network by decoupling the network control plane from the data plane …
