Örnek Metin	In this article, we propose multiple-relay selection schemes for multiple source nodes in amplify-and-forward wireless relay networks based on the sum capacity maximization criterion. Both optimal and sub-optimal relay selection criteria are discussed, considering that sub-optimal approaches demonstrate advantages in reduced computational complexity. Using semi-deﬁnite programming convex optimization, we present computationally eﬃcient algorithms for multiple-source multiple-relay selection (MSMRS) with both ﬁxed number and varied number of relays. Finally, numerical results are provided to illustrate the comparisons between diﬀerent relay selection criteria. It isdemonstrated that optimal varied number MSMRS outperforms optimal ﬁxed number MSMRS under the same power constraints.
