There are some common network control issues in IP over WDM(IP/ WDM) which includes network addressing, neighborhood discovery, routing behavior, connection setup and tear down, signaling mechanism, network access control and IP/ WDM protection and restoration. Among them network addressing and restoration are two major research area. In this paper these two issues have been discussed. This pap...

This paper proposes a rerouting scheme that can be applied to the restoration of working Label Switched Paths (LSPs) and preprovisioned backup LSPs, which consists of two subsequent algorithms. The first algorithm for the dynamic deterimination of the restoration scope (RS)increases the restoration speed by minimizing the complexity of the network topology and by maximizing the reusability of t...

Link restoration and path restoration are the two major techniques used for telecom network restoration in DCS (Digital Cross-connect System) mesh networks. For rerouting to be possible, su cient spare capacity must exist in the links of the chosen alternate paths. Path restoration results in lower additional cost compared to link restoration. Tra c splitting can be used to further reduce the a...

The network reconfiguration for service restoration in distribution systems is a combinatorial complex optimization problem that usually involves multiple non-linear constraints and objectives functions. For large networks, no exact algorithm has found adequate restoration plans in real-time, on the other hand, Multi-objective Evolutionary Algorithms (MOEA) using the Node-depth enconding (MEAN)...

Abstract Self-similarity refers to the image prior widely used in restoration algorithms that small but similar patterns tend occur at different locations and scales. However, recent advanced deep convolutional neural network-based methods for do not take full advantage of self-similarities by relying on self-attention modules only process information same scale. To solve this problem, we prese...

Failures in the water distribution network are some most important factors in water losses, water shortage and dissatisfaction of users and secondary pollutions as well. This research aimed to analyze failure in water distribution networks during 2006-2008, for better water management. Daily failure reports in Ahvaz, Iran distribution network during 2006-2008, were collected from emergency depa...

Network reconfiguration and emergency power vehicles (EPVs) dispatching are widely used in distribution networks for load restoration. However, their capabilities limited by the allocated amounts of circuit breakers EPVs. E-taxis can also participate restoration as a kind mobile energy storage using vehicle to grid (V2G) technology. uncertainty should be considered To achieve better effectivene...

tehran is one of the most polluted metropolises in the world. sink capacity for absorption and assimilation of pollution is reduced generally due to failure in inclusion of ecological aspects in regional land use development planning. the present condition of air and water related issues in tehran are greatly affected by landscape structural alterations at urban level. in this research the focu...
