In this work, we address the relay selection problem for the wireless powered\ncommunication networks, where the relays harvest energy from the source radio\nfrequency signals. A single source-destination pair is considered without a\ndirect link. The connecting relay nodes are equipped with storage batteries of\ninfinite size. We assume that the channel state information (CSI) on the\nsource-relay link is available at the relay nodes. Depending on the\navailability of the CSI on the relay-destination link at the relay node, we\npropose different relay selection schemes and evaluate the outage probability.\nThe availability of the CSI at the relay node on the relay-destination link\nconsiderably improves the performance due to additional flexibility in the\nrelay selection mechanism. We numerically quantify the performance for the\nproposed schemes and compare the outage probability for fixed and equal number\nof wireless powered forwarding relays.\n
