The main target of this paper is to study the propagation characteristics of an outdoor and indoor user utilizing 5G system at higher frequency in a courtyard surrounded by building walls i.e. small cell environment. This research work is carried out by doing 3D ray tracing simulations utilizing "sAGA" – a 3D ray tracing tool. Unlike the conventional cellular network frequencies, the considered frequencies in the scope of this work are 15 GHz, 28 GHz and 60 GHz. For simulation routes, the results are provided in the form of received signal strength. For static points, the results are presented in the form of power angular spectrum and power delay profile. The achieved simulation results show that an adequate outdoor and indoor service can be provisioned at the considered frequencies. However, it is challenging to provide services to indoor user at 60 GHz using an outdoor base station even in such a small cell environment.

In this paper, a Hybrid Mesh-Ring (HMR) algorithm is proposed for Bluetooth networks. Three stages are proposed to determine the optimal configuration of the mesh-ring network. Firstly, a designated root advertises and discovers its neighboring nodes. Secondly, a scatternet criterion is built to compute the minimum number of piconets and to distribute the connection information for piconet and scatternet. Finally, a systematic peak-search model is designed to determine the optimal mesh-ring configuration for various sizes of networks. This model includes three functional blocks: a topology formation block generates the mesh-ring topology, a routing efficiency block computes the routing performance, and an optimum decision block introduces a decision-making criterion to determine the optimum number of mesh links. Simulation results demonstrate that the optimal configuration can be obtained and the proposed HMR topology outperforms the conventional ring-based method in terms of throughput performance for Bluetooth networks.

The physics and economics of cellular networks often means that there is a need to treat some services differently. This reality has spawned several technical mechanisms in the industry (e.g. DiffServ, QCI) and lured policymakers to promulgate, sometimes, unclear service classes (e.g. FCC’s non-BIAS in the US). Yet, in the face of Net Neutrality expectations, this mixture of technical and policy toolkit has had little commercial impact, with no clear roadmap on how cellular operators should differentiate between services. Worse, the lack of clarity has disincentivised innovations that would increase the utilisation of the network or improve its operational efficiency. It has also discouraged the introduction of more customer choice on how to manage the priority of their own services. As policymakers begin the process of crafting the rules that will guide the 5G era, our contribution in this position paper is to bring better clarity on the nature and treatment of differentiated services in the industry. We introduce a clarifying framework of seven differentiated service classes (statutory, critical, best effort, commercially-preferred, discounted, delayed and blocked). Our framework is designed to shape discussions, provide guidance to stakeholders and inform policymaking on how to define, design, implement and enforce differentiated service classes in the 5G era.

Multi-access edge computing (MEC) is expected to mitigate delays and more flexibly provide services by virtualizing service functions and deploying them closer to users. However, live migration of virtual machine (VM) that enables relocation of service functions for flexible service provision may cause temporary delays or packet loss. For future deployment of MEC, it is therefore important to investigate whether responsiveness improves as expected, and to evaluate the effects of service function relocation on application-level delay experienced by users. In this paper, we investigate application-level delay in a MEC environment for services such as video live streaming. Experiments in the MEC environment constructed within our laboratory reveal that application-level delays are reduced by 15– 30%, and that application-level delay is improved by relocating remote service functions at an edge close to the user. We also reveal that delays and packet loss due to VM live migration are very temporary, confirming that service function relocation is useful for maintaining application-level delay.

5G millimeter wave devices and low frequency devices have different FCC compliance requirements. The 5G millimeter wave devices must meet new parameters such as sum of equivalent isotropic power (EIRP) and total radiated power (TRP). Massive MIMO devices must be evaluated differently as compared to conventional MIMO devices. The network telecommunications equipment EMC standard, GR1089 sets test levels for radiated immunity testing at millimeter wave frequencies. This document discusses 5G device test draft test methods and testability challenges for meeting FCC compliance and new radiated immunity requirements

The next mobile generation, 5G, is expected to bring an enormous amount of new services and increased user experience. However adequate protection mechanisms for data and user privacy are required as this new technology will play a crucial role in society by connecting vertical industries, such as smart-grids, e-health, finance, transport and manufacturing. In this paper, we identify the most important privacy issues caused by the new technologies planned to use in 5G. Then, we discuss the objectives for privacy protection in 5G and correlate the identified issues with these objectives. Finally, we highlight how these objectives can be met by both a regulatory and technological approach. To this end, several privacy preserving technological solutions are presented for 5G networks.

Food production by conventional means is not sufficient to cater for the ever growing world population. A solution is to incorporate greenhouses into the farming system more firmly. Automating these greenhouses makes the process more efficient and reliable. This project automates greenhouse farming by regulating climatic conditions in the greenhouse according to the plant specified from the database. The plants are kept at optimum temperature, humidity, light and soil moisture levels with little or no input from the user. Regular updates can be viewed from an android application and controllers can be directly activated over the internet with the click of a button. This is done with the aid of an android application and online databases such as Thingspeak. The result of this project is an easier and more efficient means of managing plant growth and a means of enhancing food production. With the aid of the project, anyone can access high yield of farming and therefore be self-sustainable in the aspect of food production.

Ultra-reliable and low-latency communication (URLLC) is one of the most important communication scenarios in the fifth generation (5G) cellular networks, which is promising to enable real-time wireless control systems. One of the biggest challenges is to integrate URLLC and control performance together to maximize the overall system performance. In my research, I would like to deal with challenge from the perspective of communication-control co-design. By the research, we expect to obtain the basic principle in the deploy of URLLC in real control systems to maximize the overall system performance.

Virtual reality is one of the most challenging use cases in 5G due to the need for simultaneous support for high data rates, low-latency and high-reliability. In this work, we consider a radio resource efficient mechanism for the mass delivery of such content to a multitude of users with D2D augmented 5G broadcast. Based on detailed performance evaluations conducted using 5G system setting, it is shown that the optimized mechanism can provide significant gains in terms of cell-edge user throughput and resultant spectral requirements for broadcast. The performance gains are obtained due to the ability of the system to optimize the operating point, instead of targeting the worst user which has been the traditional approach for broadcast. The proposed mechanism could be an enabler for mitigating the key challenges currently foreseen for the broadcast of such immersive content.
