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 …

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 …

Cooperative diversity envisages to provide improved quality of service at the physical layer,
with the assumption that wireless nodes are always willing to cooperate. This assumption …

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 …

Existing cooperative communications protocols are designed with the assumption that users
always behave in a socially efficient manner. This assumption may be valid in networks …

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 …

Cooperative transmission is an emerging wireless communication technique that improves
wireless channel capacity through multiuser cooperation in the physical layer. It is expected …

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 …

MCN-MR (Multi-hop Cellular Network-Mobile Relay) has been proposed as a promising
technology for future Beyond 3G and 4G systems due to its foreseen capacity to increase …

Existing cooperative diversity protocols are designed with the inherent assumption that
users exhibit cooperative behavior all the time. However, in a practical cooperative wireless …
