A Tabu Search Based Solution Approach to the Competitive Multiple Allocation Hub Location Problem

The hub location problems (HLP) constitute an important class of facility location problems that have been addressed by numerous operations researchers in recent years. HLP is a strategic problem frequently encountered in designing logistics and transportation networks. Here, we address the competitive multiple allocation HLP in a duopoly market. It is assumed that an incumbent firm (the leader...

Neuron - A Wide-Area Service Discovery Infrastructure

A wide-area service discovery infrastructure provides a repository in which services over a wide area can register themselves and clients everywhere can inquire about them. In this paper, we discuss how to build such an infrastructure based on the peer-to-peer model. The proposed system, called Neuron, can be executed on top of a set of federated nodes across the global network and aggregate th...

Center Selection and Migration for Wide - area

Interdomain multicast routing is a challenge, requiring a scalable solution that is suitable for diverse application characteristics. Center-based routing trees overcome some of the limitations associated with traditional shortest-path tree routing, however they present a new set of routing problems. Speciically, the choice of the center router can be critical in determining the multicast routi...

Secure & agile wide-area virtual machine mobility

Global Information Grid (GIG) operations would benefit greatly from improved support for virtual machines (VMs) that can migrate not only between physical devices within a datacentre, but also between physical devices located on different continents, while maintaining their existing IP communications sessions. Such VM migration can enable improvements with: CPU load-balancing, network traffic-e...
