Introduction The Willow architecture provides a comprehensive architectural approach to the provision of survivability [8] in critical information networks. It is based on the notion that survivability of a network requires reconfiguration at both the system and the application levels. The Willow notion of reconfiguration is very general, and the architecture provides reconfiguration mechanisms...

Wireless Mesh Network (WMN) is one of the essential elements in the networks of the future because of its ability to provide high bandwidth wireless backbone covering a large physical region. Generally single radio mesh nodes operating on a single channel suffer from capacity issues and hence it is essential to equip mesh routers with multiple radios using multiple non overlapping channels. But...

This study aimed to minimize energy losses in traditional distribution networks and microgrids through a network reconfiguration and phase balancing approach. To address this problem, an algorithm composed of a multi-objective function and operation constraints is proposed. Network connection matrices based on graph theory and the backward/forward sweep method are used to analyze power flow. A ...

The paper proposes a self-learning evolutionary multi-agent system for distribution network reconfiguration. The network reconfiguration is modeled as a multi-objective combinational optimization. An autonomous agent-entity cognizes the physical aspects as operational states of the local substation, the agent-entities establish relationship network based on the interactions to provide service. ...

Reconfiguration is the action of modifying the operation or behaviour of a system, a network node, or functional entity. The end-to-end notion dictates that, in certain cases, control and management plane interactions may occur from source to destination in order to adapt the system, the equipment, the application, the service, or the content. This paper describes an integrated control and mana...

Although advances in wireless networks and the increasing availability of mobile end devices raise the prospect of ubiquitous access to network-based services, such access must cope with an inherent mismatch between the high bandwidth, relatively static connection requirements of many services and the low bandwidth, limited resource, and dynamic nature of mobile clients. In this paper, we descr...

In an overlay network, it is important to reconfigure its network topology appropriately according to change of traffic requirements from users. An efficient dynamic topology reconfiguration method called CBP (Cluster-Based Policy), which optimizes the trade-off between communication cost and topology reconfigure cost, has been proposed. However, CBP assumes that all traffic requirements from u...

Kahn process network is a kind of data flow process networks. It is a computation model in which many concurrent processes communicate through unbounded FIFO buffer and can be executed simultaneously. In real time digital signal processing applications execution time is infinite. However, failures of implementation hardware can occur. In our work, dynamic run-time reconfiguration is introduced ...
