Cooperative-Diversity Slotted ALOHA
We propose a cooperative-diversity technique for ad hoc networks based on the decode-and-forward relaying strategy. We develop a MAC protocol based on slotted ALOHA that allows ne...

Beamforming with Limited Feedback in Amplify-and-Forward Cooperative Networks
— A relay selection approach has previously been shown to outperform repetition-based scheduling for both amplify-and-forward (AF) and decode-and-forward (DF) cooperative network...

Network Formation Games for Distributed Uplink Tree Construction in IEEE 802.16J Networks
— This paper investigates the problem of the formation of an uplink tree structure among the IEEE 802.16j network’s relay stations (RSs) and their serving base station (MR-BS)....

Physical Layer Network Coding with Multiple Antennas
: The two-phase MIMO NC (network coding) scheme can be used to boost the throughput in a two-way relay channel in which nodes are equipped with multiple antennas. The obvious strat...

Cooperative Defense Against Pollution Attacks in Network Coding Using SpaceMac
Abstract—Intra-session network coding is known to be vulnerable to pollution attacks. In this work, first, we introduce a novel homomorphic MAC scheme called SpaceMac, which all...
