In the past decade, backscatter communications have drawn significant attention as they are an ultra-low-power solution to transmit IoT sensor data, including video and audio. However, most of the state-of-the-art backscatter systems that are fully ...

In this paper, a robustness-enhanced reconstruction for the high-order finite volume scheme is constructed on the 2-D structured mesh, and both the high-order gas-kinetic scheme and the Lax-Friedrichs flux solver are considered to verify the ...

In sand-dust weather, the influence of sand-dust particles on imaging equipment often results in images with color deviation, blurring, and low contrast, among other issues. These problems making many traditional image restoration methods unable ...

This paper presents a novel radio frequency fingerprint (RFF) enhancement strategy by exploiting the physical unclonable function (PUF) to tune the RF hardware impairments in a unique and secure manner, which is exemplified by taking power amplifiers (PAs)...

Recent works have shown that by using time‐modulated arrays (TMAs), directional modulation (DM) physical‐layer secured transmitters for orthogonal frequency‐division multiplexing (OFDM) wireless data transfer can be constructed. In this paper, ...

We study a fairness-based model for 2-facility location games on the real line where the social objective is to minimize the maximum envy over all agents. All the agents seek to minimize their personal costs, and the envy between any two of them ...

As the Internet of Things (IoT) becomes increasingly popular, the amount of information transmitted through the IoT network has increased significantly. Therefore, the privacy and security problem of the transmitted information has ...

Debugging is one of the oldest yet hardest problems in the computer engineering field. People have been spending billions of dollars each year fighting with software bugs, yet debugging is still a highly inefficient process that requires a lot of ...

Online transaction processing (OLTP) databases are a critical component of modern computing infrastructure services. As a result, they must be highly available, and they must process requests efficiently for a wide range of workloads. Databases ...

Distributed software systems have become the backbone of Internet services. Failures in pro-duction distributed systems have severe consequences. A 63-minute outage of Amazon in 2018 caused a 100-million loss in revenue. Therefore, diagnosing such ...

This paper investigates a full-duplex relay network assisted by radio frequency (RF) power station in ubiquitous electric Internet of Things (UEIoT), where a wireless sensor on high voltage transmission line collects electric data and then transmits data ...

This paper explores the secrecy analysis of a multihop hybrid satellite-terrestrial relay network (HSTRN) with jamming, where one satellite source is aimed at communicating with destination users via multihop decode-and-forward (DF) terrestrial relays, in ...

With the continuous development of 5G (5th generation mobile networks) communication technology, increasing attention has been paid to the integration of 5G technology and vertical industry. Based on the consideration of power security, the large-scale ...

In this study, a new hybrid secondary transmitter (ST) mode is proposed for cognitive radio Internet of Things (CR‐IoT) networks with energy harvesting (EH) and ambient backscatter (AmBack) communication capabilities. The authors firstly describe the ...

We study a fairness-based model for 2-facility location games on the real line where the social objective is to minimize the maximum envy over all agents. All the agents seek to minimize their personal costs, and the envy between any two of them ...

We study deterministic mechanism design without money for k-facility location games with envy ratio on a real line segment, where a set of strategic agents report their locations and a social planner locates k facilities for minimizing the envy ...

In this study, the secrecy performance of the classic Wyner's wiretap model over k‐μ shadowed fading channels is studied. More specifically, the authors derive two analytical expressions for the lower bound of secure outage probability at high signal‐to‐...

Data brokers have traditionally collected data from businesses, government records, and other publicly available offline sources. While each data source may provide only a few elements about a person's activities, data brokers combine these elements to ...

The rise of smart phone usage has led to an increase in the number of applications that make use of the users' locations. One popular class of such applications is location-based social discovery (LBSD), which enables users to discover others nearby and ...

We examine third-party Online Social Network (OSN) applications for two major OSNs: Facebook and RenRen. These third-party applications typically gather, from the OSN, user personal information. We develop a measurement platform to study the interaction ...
