In order to offer a better network survivability, it is crucial that a network manager can realize restorable traffic assignment in response to traffic dynamics and facility network reconfiguration. In this paper, I presented an optimal virtual path routing control for survivable ATM networks to minimize the expected amount of lost flow upon restoration from a network failure. The amount of los...

In interconnection networks, there are several problems related to deadlock. We shall address deadlocks in the context of modularity, shortest path routing in irregular networks and fault tolerance. Deadlock freedom in interconnection networks is not a modular issue. One cannot generally combine two or more deadlock free interconnection network configurations without introducing new deadlock pr...

The exchange of Network State Beacons (NSBs) is crucial to monitoring the dynamic state of MANETs like sensor networks. The rate of beacon exchange (FX) and the network state define both the time and nature of a proactive action to reconfigure the network in order to combat network performance degradation at a time of crisis. It is thus essential to select the FX within optimized bounds, so tha...

There is a great resolution calling for smart grids in recent years. Introduction of new technologies, that make the network flexible and controllable, is a main part of smart grid concept and a key factor to its success. Transmission network as a part of system network has drawn less attention. Transmission switching as a transmission service can release us from load shedding and remove the co...

The neuronal circuit in charge of generating the respiratory rhythms, localized in the pre-Bötzinger complex (preBötC), is configured to produce fictive-eupnea during normoxia and reconfigures to produce fictive-gasping during hypoxic conditions in vitro. The mechanisms involved in such reconfiguration have been extensively investigated by cell-focused studies, but the actual changes at the net...

Wavelength division multiplexing (WDM) has emerged as a promising technology for use in backbone transport networks. In an IP/WDM network, the optical layer provides circuit-switched lightpath services to the client Internet protocol (IP) layer. The set of all the lightpaths in the optical layer defines the virtual topology. Since the optical switches (cross-connects) are reconfigurable, the vi...

Energy efficiency of software is an increasingly important topic. To achieve energy efficiency, a system should automatically optimize itself to provide the best possible utility to the user for the least possible cost in terms of energy consumption. To reach this goal, the system has to continuously decide whether and how to adapt itself, which takes time and consumes energy by itself. During ...

This paper presents an approach to the reconfiguration of radial distribution networks, for both loss reduction and service restoration, using the same metaheuristic tool: the simulated annealing algorithm. Besides the main objective of each problem (minimizing losses or load not supplied) minimization of the total number of switching device operations is also included as a possible criterion. ...

New advances in reconfigurable optical interconnect technologies will allow the fabrication of cheap, fast and run-time adaptable networks for connecting processors and memory modules in large shared-memory multiprocessor machines. Since the switching times of these components are typically high compared to the memory access time, reconfiguration can only take place on a time scale significantl...

The distribution system problems, such as planning, loss minimization, and energy restoration, usually involve the phase balancing or network reconfiguration procedures. The determination of an optimal phase balance is, in general, a combinatorial optimization problem. This paper proposes optimal reconfiguration of the phase balancing using the neural network, to switch on and off the different...
