Online Optimization of Wireless Powered Mobile-Edge Computing for Heterogeneous Industrial Internet of Things

Abstract: A spurt of progress in wireless power transfer (WPT) and mobile edge computing (MEC) provides a promising approach for Industrial Internet of Things (IIoT) to enhance the quality and productivity of manufacturing. Scheduling in such a scenario is challenging due to congested wireless channels, time-dependent energy constraints, complicated device heterogeneity, and prohibitive signaling overheads. In this paper, we first propose an online algorithm, called energy-aware resource scheduling (ERS), to maximize th… Show more

“…RF ICs are widely used in many wireless network environments, and some algorithms [ 64 , 65 ] to optimize throughput have promoted the performance of wireless devices, which also provides opportunities for HTs. For example, the forward error correction (FEC) encoder in the wireless routing of the transmitter is implanted with HT.…”

“…Therefore, in each small cell, the edge node takes the role to jointly coordinate the time portion allocation for uplink and downlink. For fairness concerns, there are typically three schemes to tackle the doubly near-far problem in WPCN: 1) deploying devices physical location delicately [8]; 2) leveraging device cooperations [18]; and 3) designing fairness embedded system utility functions [20], [29]. Unlike WPCN, which only considers the doubly near-far problem, wireless powered MEC in IIoT also needs to put device heterogeneity and available computing resources in mind during its scheduling mechanism design.…”

“…The parameters used in the simulation are taken from 3GPP specifications [33], [34] and existing synthetic data set [18], [20], to capture the features of practical dynamic environments. Specifically, the channel is modeled after the Rayleigh fading model in [20] with 0.2MHz bandwidth and 10 −9 W receiver noise power. The transmission power of the edge node is 2W and the energy harvesting efficiency of devices is set as 0.8.…”
