In this paper, we propose a new approach of network performance analysis for the uplink (UL) of cellular networks, which is based on deterministic network analysis using Gaussian approximation (DNA-GA). First, we present the DNA-GA analysis to investigate the UL signal-to-interference ratio (SIR) performance. Second, we introduce two approaches for upgrading the DNA-GA analysis to a macroscopic analysis. Finally, we perform a comparison of the performance between the proposed DNA-GA analysis and the existing macroscopic analysis based on stochastic geometry. Our results show that the DNA-GA analysis possesses a few special features: (i) shadow fading is naturally considered in the DNA-GA analysis while it is not the case with the stochastic geometry analysis; (ii) the shape and/or the size of cell coverage areas in the DNA-GA analysis can be made arbitrary for the treatment of hotspot network scenarios; (iii) the proposed DNA-GA analysis can handle nonuniform user distributions; (iv) the DNA-GA analysis can cope with any type of multi-path fading; (v) the DNA-GA analysis can be applied to multi-antenna base stations (BSs). These features make the DNA-GA analysis very useful for network performance analysis of the 5th generation (5G) systems with general cell deployment and user distribution, both on a microscopic level and on a macroscopic level.

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
