This paper investigates the problem of secure communication for amplify-and-forward (AF)
systems with untrustworthy relay nodes. To achieve positive secrecy rate, the destination …

The resource allocation problem is investigated for relay-based multi-user cooperative
Orthogonal Frequency Division Multiple Access (OFDMA) uplink system, considering …

In this paper, we analyze the symbol error rate (SER) performance of decode-and-forward
(DF) cooperative communications over Nakagami-m fading channels. For the classical three …

Cooperative communication has received tremendous interest for wireless networks. Most
existing works on cooperative communications are focused on link-level physical layer …

This letter presents an analysis of the combined use of cooperative diversity and multiuser
diversity (MUD) in multi-source multi-relay networks. A joint selection scheme, which selects …

In this paper, with the cross-layer design principle, a novel cooperative triple busy tone
multiple access (CTBTMA) scheme is proposed for wireless networks to achieve cooperative …

Cooperative devices and mechanisms are increasingly important to enhance the
performance of wireless communications and networks, with their ability to decrease power …

Green energy is emerging as a promising alternative energy source to power network
devices in next-generation wireless networks. Different from traditional energy, green energy …

Node cooperation has been demonstrated promising in system performance improvement
for wireless networks. To effectively provision packet-level quality-of-service (QoS) in …

Recently developed cooperative protocol with distributed path selection provides a simple
and practical means of achieving full cooperative diversity in wireless networks. While the …
