Wireless energy harvesting massive MIMO relays

2016 IEEE Sensor Array and Multichannel Signal Processing Workshop (SAM), 2016
The trade-off between the achievable sum rate and harvested energy is investigated for multi-user/multi-cell massive multiple-input multiple-output (MIMO) relay networks. To this end, the antenna array at the relay is switched periodically between the energy harvesting and information processing modes, and the harvested energy is utilized for the relay'

Solar Energy Harvesting for Wireless Sensor Networks

2009 First International Conference on Computational Intelligence, Communication Systems and Networks, 2009
The commercially available sensor nodes are battery-driven devices. A number of nodes together constitute a network. As days proceed, the batteries used in the nodes lose their charge and subsequently get isolated from the network. Many energy harvesting schemes have been proposed to alleviate this problem.
