Hyper-connected meshes are a growing idea that improves the connectivity in core networks. This approach adds several links to the existing core network to make it more dense and increases the number of simple paths in the network. There are several approaches to add these links to the network. In this work, we compare the robustness of the different approaches on different topologies and identify the best approach to add links in terms of robustness. 

We already have our tool to develop robustness surfaces for the given network. The student is expected to use this tool and compare the robustness of different approaches and make meaningful inferences.

Prerequisites

The interdependence of communication networks and electrical power grids is a topic of discussion in recent times. Though researchers try to map the interdependence, there are no topology-level frameworks that have data on both communication networks and electrical power grids. This work aims to generate such topology-level frameworks to publish as open-source to encourage research along this direction.

Prerequisites

A cut set of a flow is a set of components when removed, cause the flow to fail. A cut set is minimal if it cannot be further reduced. Based on minimal cut sets for flows, this work aims to investigate a potential centrality metric to determine the importance of particular nodes in the network. 

Prerequisites

Reliability Block Diagrams (RBDs) are visual aids that help evaluate the availability of a system. In communication networks, the availability evaluation is often computation and memory-intensive owing to the large size of the topologies. Hence, we investigate a novel approach of evaluating RBDs using minimal path sets.
