In this paper, the performance of a dual-hop multiuser underlay cognitive network is
thoroughly investigated by using a decode-and-forward (DF) protocol at the relay node and …

In this paper, we consider an opportunistic transmission scheme of nonregenerative relay
networks consisting of a source, a destination, and an untrusted relay, where the relay has a …

The stability regions of two opportunistic scheduling policies, ie, utility-based (UB)
scheduling and the channel-rate-based (CRB) scheduling, in wireless networks are …

The dramatic increase of mobile devices and mobile subscriptions for delay-sensitive high-
