De-Preferential Attachment Random Graphs
In this work we consider a growing random graph sequence where a new vertex is less likely to join to an existing vertex with high degree and more likely to join to a vertex with low degree. In contrast to the well studied \emph{preferential attachment random graphs} \cite{BarAlb99}, we call such a sequence a \emph{de-preferential attachment random graph model}. We consider two types of models, namely, \emph{inverse de-preferential}, where the attachment probabilities are inversely proportional…

Secure and Decentralized Peer-to-Peer Energy Transactions using Blockchain Technology
This paper presents an optimal peer-to-peer (P2P) energy transaction mechanism leveraging decentralized blockchain technology to enable a secure and scalable retail electricity market for the increasing penetration of distributed energy resources (DERs). A decentralized bidding strategy is proposed to maximize individual profits while collectively enhancing social welfare. The market design and transaction processes are simulated using the Ethereum testnet, demonstrating the blockchain network'…
