. In this paper, we study the problem of relay selection for a wireless cooperative network in context of IEEE 802.16j emerging standard. We propose Best relay selection method, which selects outage optimal relay station for each subchannel. We provide analytical...

In this paper, a new scheme is suggested for cooperative beamforming (BF) and relay selection in CR

networks, where a pair of secondary users communicates with each other assisted by some multiple antenna relay nodes. The goal...

.

Therefore, for a relay selection scheme, the choices of relay location, and the reputation of each user as well as signal-to-noise ratio, which is the main criterion for relay selection schemes, are important selection parameters. This paper...

Abstract—In this paper, we propose a new relay selection

scheme for multi-user cooperation communications using a novel

multiple criteria decision making optimization method. We consider

jointly three criteria in our proposed...

In this paper we propose a novel relay selection

method for cooperation communication networks using fuzzy

logic. Many efforts have been made in the literature to se-

lect the superior relay based on relay’s SNR/SER and / or...

In this paper, a new algorithm is proposed for cooperative beamforming, power allocation and relay

selection in the multiple input multiple output (MIMO) Orthogonal Frequency Division Multiple Access (OFDMA) CR ...

for cooperative beamforming, power allocation and relay selection in the multiple input multiple output (MIMO) cognitive radio systems where a pair of secondary user communicates with each other assisted by a set of single antenna relay nodes. The objective...
