Wireless sensor networks (WSNs) are autonomous networks of spatially distributed sensor nodes that are capable of wirelessly communicating with each other in a multihop fashion. Among different metrics, network lifetime and utility, and energy consumption in terms of carbon footprint are key parameters that determine the performance of such a network and entail a sophisticated design at different...
Anti-jamming interference alignment (IA) algorithm is an effective method to battle with adversarial jammers. Nevertheless, the abundant power from the jammers and interferences can be harvested by the legitimate users as a natural power supply. In this paper, we propose a novel anti-jamming IA scheme with wireless energy harvesting (EH). In the scheme, the power partition coefficient and transmit...
In this paper, we aim at green small cell networks by jointly achieving self-backhaul and energy harvesting. We study full duplex (FD) technology and massive multiple-input and multiple-output (MIMO) technology to enhance the performance. In order to improve the energy efficiency (EE) further, we design a precoding scheme to eliminate the inter-tier interference. Moreover, we formulate the cell association...
Interference alignment (IA) is an effective approach for interference management in wireless networks. Nevertheless, the interferences in IA networks are usually leveraged to separate out the desired signal and then discarded, instead of re-utilizing the interferences. Recently, wireless power transfer (WPT) has been introduced to harvest energy in IA networks, however, its performance still can be...
Wireless energy harvesting (WEH) is becoming one of the key techniques in energy harvesting in wireless networks. On the other hand, interference alignment (IA) is a promising solution for interference management in wireless networks. Although plenty of effort has been conducted on WEH and IA, these two important areas have been addressed separately in most of the existing literature. In this article...
Interference alignment (IA) is a promising solution for interference management in wireless networks. On the other hand, simultaneous wireless information and power transfer (SWIPT) has become an emerging technique. Although some works have been done on IA and SWIPT, these two important areas have traditionally been addressed separately in the literature. In this paper, we propose to use a common...
