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 representation of vehicular transportation in fifth generation (5G) networks requires complete projection of virtual reality that surrounds any of the vehicles at a specific location. The challenge obviously appears when trying to identify what type of data is to be captured and how such data would be processed. In reality, there would be multiple sensors that monitor and sense the physical domain with multi-service management entities for each category of these sensors. The 3rd Generation Partnership Project (3GPP) provides technical specification for such data modeling in TS 22.261 to handle multi-model virtual reality (VR) applications. This standard shows the management of multi-modality outputs, data transfer over separated links, and the multi-service processors per data type. Obviously, the success of such a system is very dependent on synchronizing the data transfers across a large network to multiple destinations and the retrieval of outputs to build the VR at the central unit of the transportation system. Although this seems to be a little similar to multi-slice services that 5G supports, this modeling is very much dependent on achieving time alignment between data transactions. The technical enablers for such a system will range from cross-service analytics capture to cross-domain orchestrators. Considering the strict key performance indicators (KPls) for transport VR and dynamic adaptation in cloud-based networks, it is most likely that such a system will not be deployed until the next mobile generation. By then, vendors and operators will have evolved the current network topology and data filtering techniques to be able to support such multi-modality platforms with high user experience.

Smart grid enhances the power grid with information and communication technologies, such as control systems, network communication, and computation facilities, to enable two-way exchange of electricity and information between operation centers and smart meters, while making the grid more reliable, efficient, secure and greener [1]. In smart grid, operation centers are allowed to collect and analyze real-time power consumption and local energy generation for distribution management, outage identification, state estimation and dynamic billing. The operation centers share electricity consumption to power plants, thereby help power plants to adjust energy production and reduce the demand to fire up costly and secondary power plans [2]. Not only could the customers access real-time usage data and electricity prices, but also decrease their energy consumption by shifting the uninterrupted activities from peak time to non-peak time.

Data Privacy Protection in Smart Grid

Due to the large volumes of modern vehicles in metropolises, finding a vacant parking space has become an irritating and frustrating problem for drivers, particularly in a congested area, such as sport centers, shopping malls, and downtown [1]. The extra traffic cruising for parking spaces brings serious social problems, including traffic congestion, vehicle accident, fuel waste, and air pollution [2]. Although Google Maps and portable navigators assist drivers to discover parking garages in destinations, drivers are then faced with a problem that no vacant parking space are available [3].

In the secure mobile advertising, mobile users privately select advertisements of interest for displaying without exposing their preferences to the ad network. However, the strong privacy guarantee has uncovered limitations on gathering aggregated ad impression statistics for the ad network to enforce correct billing on the merchants who run their ad campaigns. Early efforts integrated cryptographic voting mechanism to address this challenge, which introduces additional bandwidth overhead on mobile devices due to the construction of the ballot proof. In this paper, we propose a private and efficient ad impression aggregation scheme in mobile advertising to protect the individual ad impression statistics while preventing the ad-fraud attack. The main idea of the proposed scheme is the design of an efficient cryptographic voting mechanism based on the compact hamming weight proof technique and additive homomorphic encryption. The proposed scheme has better bandwidth efficiency by reducing the ballot proof size from O(logN) to O(1), where N denotes the dimension of the ballot. Security analysis demonstrates the confidentiality of the individual impression statistics and the verifiability of the ballot proof under standard cryptographic assumptions. Experimental results consolidate that the proposed scheme is feasible for real-world implementations on mobile devices.
