Energy harvesting (EH) has recently emerged as a promising technology for next-generation green wireless networks, as it can power communication nodes with renewable energy. However, it is challenging to provide satisfactory performance in such systems, due to the sporadic energy arrival and the low harvesting rate. In this paper, we propose a novel cooperation strategy for EH networks with the help...
In this paper, we investigate the hop distance optimization problem in ad hoc networks where cooperative multi-input-single-output (MISO) is adopted to improve the energy efficiency of the network. We first establish the energy model of multihop cooperative MISO transmission. Based on the model, the energy consumption per bit of the network with high node density is minimized numerically by finding...
A new resource allocation scheme for cooperative transmission over multiuser OFDM networks is proposed in this paper. It is assumed that each user has the ability to relay information for others to improve the overall system performance, operating in decode-and-forward (DF) mode. Sub-carriers and power are allocated to users to maximize the uplink system throughput under the constraints of half-duplex,...
