The widespread deployment of the Internet Things (IoT) is promoting interest in simultaneous wireless information and power transfer (SWIPT), performance which can be further improved by employing a reconfigurable intelligent surface (RIS). In this paper, we propose novel RIS-enhanced SWIPT system built on an electromagnetic-compliant framework. mutual-coupling effects whole are presented expli...

Inorder to enhance the capacity and output of a downlink orthogonal frequency division multiple access(OFDMA) network, it is essential to perform appropriate resource allocation. Correct resource allocation suggests that finding best subchannel and power allocation for each and every user. Therefore here associate algorithm is proposed to attain this. Initial of all sub-channel allocation is pe...

In this paper, we propose a novel joint resource allocation and cooperative caching scheme for power-domain non-orthogonal multiple access (PD-NOMA)-based heterogeneous networks (HetNets). our scheme, the requested content is fetched directly from edge if it cached in storage of one base stations (BSs), otherwise via backhaul. Our consists two phases: 1) Caching phase where contents are saved B...

Both the Mobile edge computing (MEC)-based and fog (FC)-aided Internet of Vehicles (IoV) constitute promising paradigms meeting demands low-latency pervasive computing. To this end, we construct a dynamic NOMA-based computation offloading scheme for vehicular platoons on highways, where vehicles can offload their tasks to other platoon members. cope with rapidly fluctuating channel quality, div...

The performance of Simultaneous Wireless Information and Power Transfer (SWIPT) is mainly constrained by the received Radio-Frequency (RF) signal strength. To tackle this problem, we introduce an Intelligent Reflecting Surface (IRS) to compensate propagation loss boost transmission efficiency. This paper proposes a novel IRS-aided SWIPT system where multi-carrier multi-antenna Access Point (AP)...

This paper considers Low Earth Orbit (LEO) satellite- and cache-assisted unmanned aerial vehicle (UAV) communications for content delivery in terrestrial networks, which shows great potential next-generation systems to provide ubiquitous connectivity high capacity. Specifically, caching is provided by the UAV reduce backhaul congestion, LEO satellite supports UAV’s link. In this context, we aim...

Abstract In this article, intelligent reflecting surface (IRS) aided an unmanned aerial vehicle (UAV) data collection system is investigated, where IRS deployed to assist in the communication from a cluster of Internet‐of‐Things (IoT) devices UAV presence jammer. We aim improve energy efficiency (EE) via joint design trajectory, passive beamforming, device power allocation and scheduling. Howev...

We consider convex approximations of the expected value function of a two-stage integer recourse problem. The convex approximations are obtained by perturbing the distribution of the random right-hand side vector. It is shown that the approximation is optimal for the class of problems with totally unimodular recourse matrices. For problems not in this class, the result is a convex lower bound t...
