When an ad hoc network is to be used in a disaster situation, it is likely that emergency information will be broadcast by voice streaming from a small number of nodes. Conventionally, simple flooding (SF) has been used as a method of broadcasting streams to the entire network. However, if SF is applied to information flows in which packets are generated at a high rate, as is the case with voic...

Network Function Virtualization (NFV) is an emerging paradigm that turns hardware-dependent implementation of network functions (i.e., middleboxes) into software modules running on virtualized platforms, for significant cost reduction and ease of management. Such virtual network functions (VNFs) commonly constitute service chains, to provide network services that traffic flows need to go throug...

This work presents a bandwidth management mechanism to be used with mapping mechanisms between Integrated Services (IntServ) and Differentiated Services (DiffServ) domains. The mapping mechanisms have a dynamic nature and are associated with the Admission Control functions such that the state of the network is reflected in the admission decisions of new IntServ flows into the DiffServ network. ...

Dynamic addition of computation in the interior of the network holds significant promise for improving overall end-to-end application performance, either by exposing and exploiting global network context, or by placing functionality strategically within the network. This observation has motivated the study of extensible router architectures, especially for routers at the network edge. In this p...

In this study a supply chain network design model has been developed considering both forward and reverse flows through the supply chain. Total Cost, environmental factors such as CO2 emission, and social factors such as employment and fairness in providing job opportunities are considered in three separate objective functions. The model seeks to optimize the facility location proble...

The propagation of traffic congestion along roads is a commonplace nonlinear phenomenon. When many roads are connected in a network, congestion can spill from one road to others as drivers queue to enter a congested road, creating further nonlinearities in the network dynamics. This paper considers the node model problem, which refers to methods for solving for cross-flows when roads meet at a ...

in this paper, the application of neural networks for simulation and optimization of the cogeneration systems has been presented. cgam problem, a benchmark in cogeneration systems, is chosen as a casestudy. thermodynamic model includes precise modeling of the whole plant. for simulation of the steadysate behavior, the static neural network is applied. then using dynamic neural network, plant is...

In this work, we investigate flow migration as a mechanism to sustain QoS to network users during short-term overloads in the context of an MPLS IP network. We experiment with three different control techniques: static long-term optimal mapping of flows to LSPs; on-line locally optimal mapping of flows to LSPs at flow set-up time; and dynamic flow migration in response to transient congestion. ...
