An Achievability Result for the General Relay Channel
We consider the general relay channel. For this setup, the best achievability result was derived by Cover and ElGamal, in theorem 6 of their paper from 1979. In this work we apply...

Relay node placement in large scale wireless sensor networks
Scalability and extended lifetime are two critical design goals of any large scale wireless sensor network. A two-tiered network model has been proposed recently for this purpose....

On the Capacity and Diversity-Multiplexing Tradeoff of the Two-Way Relay Channel
This paper considers a multiple input multiple output (MIMO) two-way relay channel, where two nodes want to exchange data with each other using multiple relays. An iterative algor...

An Asymptotically Optimal RFID Authentication Protocol Against Relay Attacks
Abstract. Relay attacks are a major concern for RFID systems: during an authentication process an adversary transparently relays messages between a verifier and a remote legitimate...

Relay vs. User Cooperation in Time-Duplexed Multiaccess Networks
The performance of user-cooperation in a multi-access network is compared to that of using a wireless relay. Using the total transmit and processing power consumed at all nodes as...

A Non-differential Distributed Space-Time Coding for Partially-Coherent Cooperative Communication
In a distributed space-time coding scheme, based on the relay channel model, the relay nodes co-operate to linearly process the transmitted signal from the source and forward them ...
