This paper studies an energy-efficient scheme for cooperative multi-hop communications in a finite density opportunistic large array (OLA) network. In a cooperative OLA network, a group of nodes transmits the same message signal to another group of nodes, providing range extension and increased reliability by exploiting the spatial diversity in a wireless(More)
This paper studies an approach towards employing network coding in device-to-device (D2D) network. In a D2D network, the devices in proximity establish direct links for communication instead of utilizing the cellular links. In this paper, relay-aided network-coded (RANC) D2D network is compared with a simple relay-aided D2D network. A D2D network with three(More)
This paper studies energy-efficient relay selection schemes for cooperative multi-hop device-to-device (D2D) networks. D2D networks exploit proximity gain by establishing direct links between devices instead of relying on cellular links for communication. We consider a D2D network with random deployment of relay nodes between the source and the destination.(More)
