Optimization models related to designing and operating complex systems are mainly
focused on some efficiency metrics such as response time, queue length, throughput, and …

Applications of optimization is countless. Every process has a potential to be optimized.
There is no company which is not involved in solving optimization problems. Indeed, many …

Topology impacts important network performance metrics, including link utilization,
throughput and latency, and is of central importance to network operators. However, due to …

In this paper, we consider multicommodity flow problems, with unsplittable flows and
piecewise linear routing costs. We first focus on the case where the piecewise linear routing …

The increasing adoption of server virtualization has recently favored three key technology
advances in data-center networking: the emergence at the hypervisor software level of …

The hyper hexa-cell (HHC) interconnection network is relatively a new interconnection
network, which is constructed from hexa-cell and hypercube topologies. HHC is developed …

Switched Ethernet networks rely on the Spanning Tree Protocol (STP) to ensure a cycle-free
connectivity between nodes, by reducing the topology of the network to a spanning tree. The …

In this paper, we study the problem of routing, bandwidth and flow assignment in wireless
body area networks (BANs). We present an adaptive joint routing and bandwidth allocation …

In this Chapter, we consider the hybridization of column generation (CG) with metaheuristics
(MHs) for solving integer programming and combinatorial optimization problems. We …

In this paper, a hybrid meta-heuristic is proposed which combines the GRASP with path
relinking method and Column Generation. The key idea of this method is to run a GRASP …
