What happens when cognitive terminals compete for a relaying node?
We introduce a new channel, which consists of an interference channel (IC) in parallel with an interference relay channel (IRC), to analyze the interaction between two selfish and...

Impact of Mobility on the Performance of Relaying in Ad Hoc Networks
— We consider a mobile ad hoc network consisting of three types of nodes: source, destination, and relay nodes. All the nodes are moving over a bounded region with possibly diffe...

Power Allocation and Coverage for a Relay-Assisted Downlink with Voice Users
— We study the downlink coverage of a base station terminal (BST), which has access to a relay node. Continuing a previous study in which the BST is assumed to provide a variable...
