IEEE Project Abstract

Internet-of-Things (IoT) is a promising technologyto connect massive machines and devices in future communicationnetworks. In this paper, we study a wireless-powered IoTnetwork (WPIN) with short packet communication (SPC), inwhich a hybrid access point (HAP) first transmits power tothe IoT devices wirelessly, then the devices in turn transmittheir short data packets achieved by finite blokelgnth codes tothe HAP using the harvested energy. Different form the longpacket communication in conventional wireless network, SPCsuffers from a transmission rate degradation and a significantpacket error rate. Thus conventional resource allocation inthe existing literature based on Shannon capacity achieved byinfinite blocklength codes is no longer optimal. In this paper,to enhance the transmission efficiency and reliability, we firstdefine effective-throughput and effective-amount-of-information asthe performance metrics to balance the transmission rate and thepacket error rate, and then jointly optimize the transmissiontime and packet error rate of each user to maximize thetotal effective-throughput or minimize the total transmissiontime subject to users’ individual effective-amount-of-informationrequirements. To overcome the non-convexity of the formulatedproblems, we develop efficient algorithms to find high-qualitysuboptimal solutions for them. Simulation results show that theproposed algorithms can achieve similar performances as that ofthe optimal solution via exhaustive search, and outperform thebenchmark schemes.
