In this work, we consider a canonical three-node DF cooperative network where the relay
may misbehave with a certain probability. Without misbehavior detection, diversity …

This letter considers a three-node cooperative network with an untrusted relay. We propose
a noncoherent relay misbehavior detection scheme for decode-and-forward (DF) systems …

We study the detection of misbehavior in a Gaussian relay system, where the source
transmits information to the destination with the assistance of an amplify-and-forward relay …

Consider a two-relay decode-and-forward (DF) cooperative network where Alamouti coding
is adopted among relays to exploit spatial diversity. However, the spatial diversity gain is …

In this letter, a detect-before-decode (DbD) method for relay misbehavior detection in a
wireless decode-and-forward (DF) cooperative network is proposed. Since this method …

In this paper, we analyze the bit error rate (BER) and the throughput of decode-and-forward
(DF) relaying with imperfect channel estimation and in the presence of a jammer in the …

We consider a cooperative diversity scheme where a relay cooperatively enhances
communication between a source and destination. In cooperative diversity, due to lack of a …

We propose the maximum a posteriori (MAP) detection of the misbehaving relay that injects
false data or adds channel errors into the network encoder in multiple access relay …

A cooperative communication system explores a new dimension of diversity in wireless
communications to combat the unfriendly wireless environment. While this emerging …

The success of cooperative communications hinges on the reliability of cooperating nodes
between the communicating parties, which may not be guaranteed in realistic scenarios. To …
