Wireless energy harvesting in interference alignment networks with adversarial jammers
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 power are jointly optimized to minimize the total transmit power of the network, with the requirements of sum rate and harvested energy guaranteed. To further reduce the complexity of the joint optimization, a suboptimal algorithm is also developed with lower complexity. Extensive simulation results are presented to show the effectiveness of the proposed anti-jamming IA scheme with wireless EH.
