This paper investigates the relay selection (RS) problem in networks with multiple users and
multiple common amplify-and-forward (AF) relays. We first give an optimality measure for RS …

This paper studies relay selection schemes for two-way amplify-and-forward (AF) relay
networks. For a network with two users that exchange information via multiple AF relays, we …

This paper is on relay selection (RS) schemes for wireless relay networks. First, we derive
the diversity of many single RS schemes in the literature. Then, we generalize the idea of RS …

This paper considers the relay subset selection problem in a two-way amplify-and-forward
relay network, where each user is equipped with multiple antennas and each relay is …

This paper is on relay selection schemes for wireless relay networks. First, we derive the
diversity of many single-relay selection schemes in the literature. Then, we generalize the …

This paper analyzes the performance of a multi-user multihop relay network using a low
complexity decentralized relay selection (DRS) scheme for decode-and-forward cooperative …

In cooperative relay networks with multiple users and multiple potential relays, which relay
nodes are selected has great impact on the system performance. It is an optimization …

A relay selection (RS) scheme for two-way networks with multiple amplify-and-forward relays
is proposed. The scheme maximizes the worse receive signal-to-noise ratio (SNR) of the two …

We investigate the performance of multi-antenna two-way relay networks, where both
amplify-and-forward (AF) and decode-and-forward (DF) relaying strategies are considered …

We show that the performance of relay selection can be improved by employing relays with
buffers. Under the idealized assumption that no buffer is full or empty, the best source-relay …
