Title: 5G Mobile Communication: Evolution or Revolution
Abstract: The promise of 5G as next generation of mobile communication offers huge potential to service providers, application developers and wireless consumers. The features of 5G will be low latency, higher spectral efficiency, higher user density and higher date rate than 4G mobile communication. 5G not only involved connectivity to anyone and anytime but also anyone, anytime and anything supporting Internet of Things (IOT). 5G which also known as special generation not only will enhance further the mobile broadband but also intergrating machine to machine and device to device. The standardization process of 5G will be completed in year 2020. The concept of 5G will be small cell and steerable antenna. Evolution and revolution towards 5G will involve setting up more base station. Therefore the issues related to the EMF radiation from the base staion will be also need to be considered. The objective of the tutorial is to describe the evolution and revolution of the 4G mobile communication towards 5G mobile communication. The tutorial will also cover the issues related to EMF radiation from the base station as there will be more base stations added to support the 5G coverage,

Title: Fundamentals and Applications of Green Communication for Current and Future Mobile Networks
The importance of reducing energy costs, reducing CO2 emissions and protecting the environment are leading to an increased focus on energy-efficient approaches to the design of next-generation wireless networks. The aim of this tutorial is to present state-of-the-art research on green mobile communications and networking technology based on the fundamental research approaches and practical deployment by the industry in the field. This tutorial will explore the network architectures and models, physical communication techniques, intelligent cooperation among the base stations, wireless access techniques, experimental test-beds and results and ongoing standardization activities. This tutorial will balance between theoretical studies and practical application in green mobile networks with highlights on potential issues and challenges. The potential of green cellular base stations based on the characteristics of Malaysia’s solar radiation exposure will be presented. At the end of the tutorial, potential of green transmission techniques in Fifth Generation (5G) network will be highlighted.

Title: OFDM-based Visible Light Communications: Potentials and Challenges
The tremendous growth of indoor communication and fundamentally Wi-Fi limitations to provide high data rate are imposed to find a new technology that can meet the user high data rate demand. The visible light communication (VLC) based on Light Emitting Diodes (LEDs) is proposed to fulfill the high data rate demand at low cost and no health risk. The approach of dual use of illumination and communication can provide high energy efficiency as well as high throughput due to the huge unlicensed optical spectrum. Orthogonal frequency division multiplexing (OFDM) in VLC is a promising technique as it can produce a higher data rate, multiple-access and reduce multipath effects. However, the high peak to average power ratio (PAPR) is a major issue in OFDM based VLC system. PAPR causes nonlinearities in the transmitted signal and increases the complexity in retrieving the original signal at the receiver and hence an accurate channel estimation technique is needed. This tutorial presents an overview of the VLC technology and explores its potential within the context of practical limitations as well as highlights some visions for the next generation of VLC systems.

Title: Towards Energy-Efficient Hyper-Dense Wireless Networks with Trillions of Devices
The information and communication technology (ICT) data traffic is expected to increase 1,000 fold by 2020. This increasing demand is quickly draining the scarce radio resources and will eventually affect our nations’ economy. This strongly motivates the need for intensive research on the next generation of wireless networks. Beyond conventional cellular data, machine-to machine (M2M) and device to device (D2D) communication will be responsible for a big portion of the wireless traffic in the next few years. This will, in turn, further strain existing wireless infrastructure and require novel designs. According to recent forecasts, there will be 12.5 billion inter-connected machine-type devices worldwide by the year 2020, up from 1.3 billion in 2012. For coping with such traffic growth, it is well known that the major technique for meeting a much needed 1000x capacity improvement will be a byproduct of massive network densification. The idea is to introduce heterogeneous networks (HetNets) having new, additional nodes, such as small cell base stations, deployed within local-area range and making the network closer to the end-users. The integration of macro/micro/pico/small cell base stations (SBSs) with disparate cell sizes and capabilities, has already been approved as a working item in LTE-advanced and 5G. Such hyper-dense and heterogeneous networks (HDHNs) can significantly improve spatial frequency reuse and coverage, thus meeting the wireless capacity crunch. For example, it is envisioned that a viral and hyper-dense deployment of low-cost small cells in the near future, with 200-300 small cells per typical macro cell coverage, approaching one-to-one ratio with the number of UEs. Such HDHNs are characterized by two unique features: a) massive number of devices and b) highly dynamic environment. How to manage, operate, and optimize such hyper-dense, dynamic networks, in an energy-efficient and sustainable manner, is an important research challenge that has recently received significant research interest from both academia and industry. The main goal of this tutorial is to introduce different aspects of designing HDHNs with advanced capabilities while focusing on spectral-efficiency (SE) and energy-efficiency (EE). In particular, we will introduce a plethora of techniques that include stochastic geometry, fuzzy logic, and game-theory that are necessary for deploying and operating large-scale, self-organizing HDHNs that can be used to support various communication systems with seamless mobility.

Title: Cross-Layer Design of Cooperative Wireless Networks
In recent years, the concept of “user cooperation diversity” has gained research impetus owing to its inherent ability to overcome the practical implementation challenge of packing a large number of antenna elements (to exploit the benefit of multiple-input-multiple-output space-time processing techniques) in small sized handheld portable devices and sensor nodes. It also holds promise to yield significant gains in coverage, reliability, throughput, energy efficiency, and network availability/life-time of legacy networks. Not surprisingly, cooperative communications is an active area of research today, and has received tremendous interest in the standardization of emerging wireless systems such as IEEE 802.11s, LTE-Advanced, IEEE 802.16j and IEEE 802.16m. However, the art of adaptive link layer and/or cross-layer optimization of cooperative wireless networks are still in their infancy although it has been long recognized that efficient resource utilization/management for cooperative wireless networks can benefit substantially from a cross-layer design paradigm (where interdependencies between multiple protocol layers are characterized and exploited while jointly optimizing the end-to-end performance metrics). This phenomena can be partially attributed to the lack of simple and general closed-form or analytical expressions that can accurately parameterize the physical layer performance of such networks, or that can be used to develop insights (e.g., diversity/coding gain) on multi-layer protocol interactions. The aim of this tutorial is hence to expose practicing engineers and academic researchers to the cutting-edge research challenges related to cross-layer design, analysis and optimization of cooperative wireless networks with link adaptation techniques. In particular, the participants will be equipped with a sufficient set of mathematical tools and analysis techniques that will facilitate efficient analysis and optimization of emerging digital cellular and wireless ad-hoc networks. Illustrative examples will be provided to demonstrate how these design tools can be used to efficiently parameterize the physical layer performance of cooperative wireless networks in generalized fading environments and dramatically simplify the cross-layer design optimization of wireless networks with link-adaptation strategies.
