Abstract

Energy harvesting (EH) has been recently proposed as a promising technology to enable green communications. By harvesting energy from the environment, communication nodes with the EH capability can improve the energy efficiency and extend the lifetime of wireless networks. To provide satisfactory performance, new communication protocols will be needed for EH communication networks. A major design challenge is due to the energy causality constraint, which means only the previously harvested energy can be used in the current transmission block. In this talk, we will introduce some recent results on the design of cooperative communication protocols for EH communication networks, which can be served as a key technique to improve the communication performance. Specifically, the following three topics will be presented: 1) Optimizing two-hop EH communication systems; 2) relay selection for cooperative EH networks; and 3) QoS provisioning in EH communication networks with multiple relays.
