We propose a new scheme to secure a wireless-powered untrusted cooperative-communication network, where a legitimate source node (Alice) transmits her information messages to a legitimate destination node (Bob) through the multiple amplify-and-forward untrusted relays. The relay nodes are assumed to be honest but curious nodes; hence, they are trusted at the service level but are untrusted at the...
We investigate the impact of the wireless network’s physical layer (PHY) security and reliability on demand-side management operation in the smart grid. We assume that consumers communicate their energy demands with the utility, and we investigate the tradeoff between the wireless network’s PHY security and reliability. We consider passive and active attacks on the smart grid, and show their impacts...
The basic challenge of data centers is how to interconnect a huge number of servers while guaranteeing the performance of the network. Flatnet is a promising data center architecture that has proved its efficiency to connect a scalable number of servers and to achieve a high network capacity, fault-tolerance and low-cost while using only one network layer. However, its long path length impacts the...
