Abstract Hollow fibers were spun from a solution of surface‐modifying macromolecule blended polyethersulfone in dimethyl acetamide by using dry‐wet spinning method at different air gaps and room temperature. The gap was varied 10 to 90 cm. ultrafiltration performance hollow studied aqueous solutions polyethylene glycols oxides molecular weights. Significant difference surface morphology between the inner outer observed atomic force microscopy (AFM). Similar results obtained contact angle...
Mobile edge computing provides the opportunity for systems to underpin a variety of computation-intensive yet delay-sensitive applications. We acknowledge that limited and storage resource an individual server allows only subset services be placed at time. This raises question service placement, which refers where place each type service. Moreover, tasks processed, thereby affects task scheduling performance, where/whether schedule splitting among cloud. Respect interactions between...
In the edge computing Internet of Things network, we minimize offloading overhead (caused by bandwidth cost for data transmission and computation resource consumption task remote processing) while providing end-to-end (E2E) delay provisioning. Under scenario, a tandem queue consisting process is formed tasks offloaded to server via wireless link then processed through resource. Due queue, decision allocation are coupled over queue. To make problem tractable, decouple above two operations...
Non-orthogonal multiple access (NOMA) is considered as a potential technique to relieve the congestion due concurrent from massive devices in machine-to-machine (M2M) communication system. However, cochannel interference caused by NOMA, and energy budget of machine-type (MTDs), become bottleneck further improve system performance. Given above issues, we formulate joint user scheduling management problem stochastic optimization problem. Specifically, goal maximize long-term average sum rate...
In this paper, we investigate the quality of information (QoI) maximization problem by jointly optimizing sampling rate, packet-dropped and transmit power in wireless sensor networks (WSNs). We consider a complicated but practical scenario, where various tasks with heterogeneous traffic are supported one WSN simultaneously. Accordingly, QoI is formulated as stochastic optimization subject to differentiated constraints. To tackle problem, Lyapunov technique applied obtain integrated...
Abstract Energy harvesting (EH) aided Internet of Things (IoT) network is a promising paradigm to librate IoT from energy deficiency. Dynamic and traffic scheduling in such scenario challenging due temporal correlation constraints delay requirements applications. In this paper, joint management sampling rate control explore the tradeoff between utility performance are studied while maintaining causality constraint. Taking into account dynamic characteristics EH process, channel fading...
