Praise for the Third Edition: "This is one of the best books available. Its excellent organizational structure allows quick reference to specific models and its clear presentation . . . solidifies the understanding of the concepts being presented."IIE Transactions on Operations EngineeringThoroughly revised and expanded to reflect the latest developments in the field, Fundamentals of Queueing Theory, Fourth Edition continues to present the basic statistical principles that are necessary to analyze the probabilistic nature of queues. Rather than presenting a narrow focus on the subject, this update illustrates the wide-reaching, fundamental concepts in queueing theory and its applications to diverse areas such as computer science, engineering, business, and operations research.This update takes a numerical approach to understanding and making probable estimations relating to queues, with a comprehensive outline of simple and more advanced queueing models. Newly featured topics of the Fourth Edition include:Retrial queuesApproximations for queueing networksNumerical inversion of transformsDetermining the appropriate number of servers to balance quality and cost of serviceEach chapter provides a self-contained presentation of key concepts and formulae, allowing readers to work with each section independently, while a summary table at the end of the book outlines the types of queues that have been discussed and their results. In addition, two new appendices have been added, discussing transforms and generating functions as well as the fundamentals of differential and difference equations. New examples are now included along with problems that incorporate QtsPlus software, which is freely available via the book's related Web site.With its accessible style and wealth of real-world examples, Fundamentals of Queueing Theory, Fourth Edition is an ideal book for courses on queueing theory at the upper-undergraduate and graduate levels. It is also a valuable resource for researchers and practitioners who analyze congestion in the fields of telecommunications, transportation, aviation, and management science.

The Feher quadrature phase shift keying (FQPSK) modulation based Physical-layer Network Coding (PNC) is investigated in this paper, by which the nonlinear distortion effects resulted from the high power amplifier (HPA) in the system can be avoided. In our presented framework, a novel remapping rule for the FQPSK modulation in the PNC system is proposed to make a better bit error rate (BER) performance. Moreover, a joint demapping-and-demodulation scheme based on Low Density Parity Check (LDPC) is employed to recover the data bits with a low computational burden. Numerical results demonstrate the efficiency of the proposed method.

Doze mode, which was introduced from Android 6.0 aiming at reducing battery consumption when the device is unused for a long time. This work firstly reveals the internal details of the battery-saving feature, especially about the state transitions. Furthermore, we discover several defects in Android's device drivers associated with doze mode. By exploiting the defects, we implement various proof-of-concept attacks that could drain battery without acquiring any permissions by subverting doze mode. The proposed attacks are silent (hardly discerned by normal users), because they keep hidden when the smartphone is in use, while letting benign applications do battery-intensive work when the smartphone is unused rather than consuming excessive power by the attacks themselves. Google has confirmed that our attacks can reduce battery life. Finally, we discuss how to defend against the proposed attacks.

Privacy-Enhancing Fog Computing and Its Applications

The future metropolitan-area wireless mesh networks (WMNs) are expected to have compromise-prone mesh access points (MAPs) with high frequency of inter-domain roaming/handoff events. To achieve security without losing efficiency, this paper introduces a novel secure localized authentication and billing (SLAB) scheme. Our scheme aims to address both security guarantee and performance in terms of system compromise resilience capability, inter-domain handoff authentication latency, and workload of the roaming broker (RB). We demonstrate that the proposed scheme can be a practical solution for achieving secure roaming and billing in metropolitan-area WMNs.

Secure Localized Authentication and Billing for Wireless Mesh Networks

Heterogeneous Network (HetNet) is a promising solution to enhance network capacity and extend network coverage by increasing cell site density in Long Term Evolution-Advanced (LTE-Advanced) systems. However, dense deployment of cell sites not only increases desired signal strength, but also intercell interference as cell sites get closer. To combat with intercell interference, Joint Processing Coordinated Multi-Point (JP CoMP) technique is introduced into LTE-Advanced systems. In this paper, we aim to theoretically evaluate JP CoMP based systems in terms of statistical average of capacity. Two typical JP schemes, including Dynamic Cell Selection (DCS) and Joint Transmission (JT) are considered. We first derive the Probability Density Function (PDF) of Signal-to-Interference Ratio (SIR) for different transmission schemes and based on this, obtain the statistical average capacity. From computer simulation, we compare the performance of the two JP schemes with non CoMP scheme. The impacts of number of cooperative cell sites, transmitting antennas, and interfering channels are also discussed.
