Optimizing network-coded cooperative communications via joint session grouping and relay node selection
Abstract—Network-coded cooperative communications (NCCC) is a new paradigm in wireless networks that employs network coding (NC) to improve the performance of CC. The core mechan...

Cooperation with an untrusted relay: a secrecy perspective
We consider the communication scenario where a source-destination pair wishes to keep the information secret from a relay node despite wanting to enlist its help. For this scenario...

On the Capacity of Bidirectional Broadcast Channels under Channel Uncertainty
We consider the broadcast phase of a spectrally efficient two-phase decode-and-forward protocol which is used by a relay node to establish a bidirectional communication between two...

Coding Strategies for Bidirectional Relaying for Arbitrarily Varying Channels
In this work we study optimal coding strategies for bidirectional relaying under the condition of arbitrarily varying channels. We consider a three-node network where a relay node ...

Constrained relay node placement in wireless sensor networks: formulation and approximations
—One approach to prolong the lifetime of a wireless sensor network (WSN) is to deploy some relay nodes to communicate with the sensor nodes, other relay nodes, and the base stati...

CR: Capability Information for Routing of Wireless Ad Hoc Networks in the Real Environment
—In greedy routing, each relay node forwards the message to a neighbor (also called successor) that is closer to the destination. However, the successor candidate set (SCS) is di...

Strong Secrecy and Reliable Byzantine Detection in the Presence of an Untrusted Relay
We consider a Gaussian two-hop network where the source and the destination can communicate only via a relay node who is both an eavesdropper and a Byzantine adversary. Both the s...
