Optimum relay sharing with statistical channel information in multiple-sensor relaying networks

In this paper, we investigate a multiple-sensor relaying network where a relay helps multiple sensor-destination pairs. We propose probabilistic relaying scheme and provide an optimal relay sharing ratio for the proposed scheme. Based on statistical channel information, the maximum outage probability between all users is minimized. Numerical results show that the proposed probabilistic relaying scheme outperforms no-relay scheme and exclusive relaying scheme .
