In this paper, we consider the optimal design of interlinks for an interdependent system of networks. In contrast to existing literature, we explicitly exploit the information of intra-layer node degrees to design interdependent structures such that their robustness against cascading failures, triggered by randomized attacks, is maximized. Utilizing percolation theory-based system equations relating...
With growing demands for cloud computing services, the idea of managing limited cloud resources for making a profit has arisen as an important problem. Auction theory is recently considered as a viable way to solve the problem of cloud resource allocation. In this paper, we consider a model for Cloud of Clouds Networks (CCNs) with different types of servers along with customers with heterogeneous...
In this work, we focus on the problem of obtaining the optimal interlink structures, which maximizes the robustness of networks against random node failures, in a cost constrained setting. Using percolation theory based system equations, we have formulated our objective as a constrained optimization problem and designed algorithms serving two key purposes: i) obtaining the budget limits, Bl and Bu...
Abstract-We consider a partially interdependent network and develop mathematical equations relating the fractional size of the connected component of the network, surviving the cascading failure, to the intra-layer degree distribution of the nodes. We show that these system equations can be mathematically analyzed and closed form expressions for the metrics of robustness can be obtained for the Erdos-Renyi...
In this work we consider the optimal design of interconnection links for an interdependent system of networks. In contrast to existing literature, we explicitly exploit the information of intra- layer node degrees to design more robust interdependency structure against cascading failures triggered by random attacks. Built on solid mathematical models, we characterize the optimal design for the one-to-one...
In the first part of this two-part paper, we initiate the study of collaborative quickest detection in an adhoc setting for a simple two-node scenario. In this part, we extend our study to the general multi-node network, where we also explicitly address information exchange protocol and network topology control. We further consider block transmission mode and correlated observations. In each scenario,...
