Download or read book An Introduction to Cellular Network Analysis Using Stochastic Geometry written by Jeffrey G. Andrews and published by Springer Nature. This book was released on 2023-06-30 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an accessible yet rigorous first reference for readers interested in learning how to model and analyze cellular network performance using stochastic geometry. In addition to the canonical downlink and uplink settings, analyses of heterogeneous cellular networks and dense cellular networks are also included. For each of these settings, the focus is on the calculation of coverage probability, which gives the complementary cumulative distribution function (ccdf) of signal-to-interference-and-noise ratio (SINR) and is the complement of the outage probability. Using this, other key performance metrics, such as the area spectral efficiency, are also derived. These metrics are especially useful in understanding the effect of densification on network performance. In order to make this a truly self-contained reference, all the required background material from stochastic geometry is introduced in a coherent and digestible manner. This Book: Provides an approachable introduction to the analysis of cellular networks and illuminates key system dependencies Features an approach based on stochastic geometry as applied to cellular networks including both downlink and uplink Focuses on the statistical distribution of signal-to-interference-and-noise ratio (SINR) and related metrics

Download or read book Analysis Modeling and Enhancement of LTE A Heterogeneous Networks in a Real World Environment written by Haijun Gao and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decades, cellular networks have been greatly developed. An increasing number of devices such as tablets and mobile phones are connected to cellular networks. The heterogeneous networks (HetNets) play an important role in serving users with different requirements and huge data demands. LTE-A HetNets have been extensively studied for many years. However, most research works have focused on theoretic studies of LTE-A HetNets. Only a few researchers have a chance to access and study the actual HetNets. A big gap exists between theories and actual applications for cellular networks. It is essential to understand the mechanism of HetNets in real-world environments for better network performance. Building a traffic model that is more suitable for the real-world environment is necessary not only for network operators to provide better service and save costs, but also for users to have better experience with strong received signals. This thesis analyzes and evaluates measured data from a real-world LTE-A HetNet, models user traffic in the actual environment, and optimizes the HetNet using the developed models. In this thesis, the real-world LTE-A HetNet is studied in detail. Both the aggregate data and UE (user equipment)'s data are investigated. The main goal is to study the actual environment, understand the mechanisms of the actual system, and model and optimize the users' actual data traffic in the real-world environment in this thesis. The aggregate data (cell level data) for the HetNet at the University of Regina are analyzed and modeled in detail for all the cells in the actual HetNet. Four indicators are introduced to evaluate the performance of cell level data. In addition, a series of data collection activities are performed at the University of Regina to better understand the real-world LTE-A HetNet. These tests are intended to analyze and evaluate the baseline of the network and measure the dynamic response of the system when the network settings are adjusted. The activities include handover tests with adjusting A3 event handover parameters and indoor cell-splitting tests with interference mitigation techniques (e.g., Almost Blank Subframe (ABS)). The characteristics of the actual scheduler of the HetNet are analyzed in depth by comparing allocated resource blocks of each test device. The performance of different typical and popular schedulers (e.g., Proportional Fair) is compared with the measured data from the real-world. A fairness guaranteed scheduler is proposed to maintain the fairness of user throughput since the fairness is a crucial indicator. This innovative scheduler is developed using the generalized proportional fair (PF) scheduler and control theory. A simulation model is developed to predict user downlink data rate in a dynamic environment with algorithms and measurement. Some indicators are also proposed for the model. Furthermore, both enhancement strategies and algorithms are proposed for the HetNet to increase cell throughput of the overall networks. This model is useful to predict user data rate more accurately and to help the network operators produce effective cell planning and provide seamless service to users. Studying the actual cellular networks will bring more insights about how the actual network behaves and will be beneficial for the deployments of 5G networks in the future, because many features in LTE-A (e.g., small cells) are also crucial to the 5G networks.
Download or read book Modelling and Analysis of Resource Management Schemes in Wireless Networks written by Zaid Ahmed Said Zabanoot and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Over recent years, wireless communication systems have been experiencing a dramatic and continuous growth in the number of subscribers, thus placing extra demands on system capacity. At the same time, keeping Quality of Service (QoS) at an acceptable level is a critical concern and a challenge to the wireless network designer. In this sense, performance analysis must be the first step in designing or improving a network. Thus, powerful mathematical tools for analysing most of the performance metrics in the network are required. A good modelling and analysis of the wireless cellular networks will lead to a high level of QoS. In this thesis, different analytical models of various handoff schemes and resource re-allocation in homogeneous and heterogeneous wireless cellular networks are developed and investigated. The sustained increase in users and the request for advanced services are some of the key motivations for considering the designing of Hierarchical Cellular Networks (HCN). In this type of system, calls can be blocked in a microcell flow over to an overlay macrocell. Microcells in the HCN can be replaced by WLANs as this can provide high bandwidth and its users have limited mobility features. Efficient sharing of resources between wireless cellular networks and WLANs will improve the capacity as well as QoS metrics. This thesis first presents an analytical model for priority handoff mechanisms, where new calls and handoff calls are captured by two different traffic arrival processes, respectively. Using this analytical model, the optimised number of channels assigned to handover calls, with the aim of minimising the drop probability under given network scenarios, has been investigated. Also, an analytical model of a network containing two cells has been developed to measure the different performance parameters for each of the cells in the network, as well as altogether as one network system. Secondly, a new solution is proposed to manage the bandwidth and re-allocate it in a proper way to maintain the QoS for all types of calls. Thirdly, performance models for microcells and macrocells in hierarchical cellular networks have been developed by using a combination of different handoff schemes. Finally, the microcell in HCN is replaced by WLANs and a prioritised vertical handoff scheme in an integrated UMTS/WLAN network has been developed. Simulation experiments have been conducted to validate the accuracy of these analytical models. The models have then been used to investigate the performance of the networks under different scenarios.
