Interference Management for Heterogeneous Networks
» Mehdi Bennis | University of Oulu, Finland
» Dusit Niyato | Nanyang Technological University, Singapore

As the spectral efficiency of a point-to-point link in legacy cellular networks approaches its theoretical limits, network densi_cation is deemed instrumental to further boost network capacity whereby challenges associated with macrocell deployment can be overcome by the utilization of low power base stations. A network that consists of a mix of macro cells and low-power nodes such as femto cells, pico cells and relays, is referred to as a heterogeneous networks (HetNets). While heterogeneous networks are poised to take the spectral efficiency to a whole new level, a gamut of technical challenges need to be tackled before making their deployment feasible. In this tutorial, first an overview of heterogenous cellular networks along with their benefits and challenges is presented. Second, interference management techniques which are critical for Long-Term Evolution (LTE/LTE-Advanced) heterogeneous deployments are presented in greater detail including concepts such as cell range expansion, cell biasing, cell selection, adaptive resource partitioning, smart relaying and self-organizing networks (SONs). Third, due to the unplanned deployment of small cells, traditional network planning and optimization becomes inefficient since operators do not know the number nor the location of these cells. This motivates the need for novel decentralized interference avoidance schemes that operate independently in each tier based only local information, while achieving an efficient network performance. In addition, with the advent of heterogenous networks, current hexagonal base station models are becoming fairly obsolete and hence new spatial and random statistical models are required. These models provide a tractable and powerful framework for computing network performance metrics such as coverage probability and spectral efficiency, as well as curtailing cumbersome Monte-Carlo simulations.

» Guowang Miao | KTH, Sweden
» Ye (Geoffrey) Li | Georgia Tech, USA

The future success of communication networks hinges on the ability to overcome the mismatch between requested quality of service (QoS) and limited network resources. Spectrum is a natural resource that cannot be replenished and therefore must be used efficiently. On the other hand, energy efficiency (EE) is also becoming increasingly important as battery technology has not kept up with the growing requirements stemming from ubiquitous multimedia applications. This tutorial introducescross-layer technologies to improve both spectral and energy efficiency from different perspectives of wireless systems. We will first discuss the basic wireless channel characteristics and the methodologies needed to enable high-performance wireless networks. Then we introduce state-of-art spectral and energy efficient communication technologies for both individual users and multi-user networks. The tutorial will be concluded by the discussion of the tradeoff between spectral and energy efficiency in interference limited networks.

Visible Light Communications (VLC): The Next Frontier for Wireless Communications
» Jean Armstrong | Monash University, Australia

Visible light communications (VLC) using LEDs is an emerging technology which is attracting rapidly increasing research interest around the world. Because of their energy efficiency,LEDs are replacing conventional incandescent and fluorescent lights in applications including indoor lighting, traffic lights and car lights. These lighting LEDs can also be used to transmit very high speed data, for example rates of 500 Mbit/s have been demonstrated using anoff-the-shelf white lighting LED. While VLC has many advantages, including large, license-free bandwidth, security and immunity from radio frequency (RF) interference, there are also many research challenges. Because intensity modulation and direct detection (IM/DD) must be used in these systems, many of the techniques developed for RF wireless communications cannot be applied. This tutorial will provide an introduction to optical wireless using intensity modulation and direct detection including the characteristics and limitations of transmitters and receivers, and information about typical optical wireless channels. It will include an overview of the status of research in visible light communications around the world, and an outline of some of the excitingemerging research challenges.

Cloud based - service delivery platforms for machine to machine communications (M2M)
» Roch Glitho | Concordia University, Canada

Machine-to-Machine communications (M2M for short) is a fundamental component of the Internet-of-Things (IoT) vision. Potential applications and services are numerous (e.g. surveillance, health), thus generating a huge degree of interest in research, standardization and product development. Cloud computing is an emerging paradigm with several facets (e.g. Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)), and many associated benefits (e.g. efficiency in resource usage, easy introduction of new applications and services, scalability, and flexibility in pricing) that motivate quite well their use as service delivery platforms. This tutorial is devoted to the use of clouds as basis for M2M service delivery platforms. We review the state of the art and discuss research challenges. Background information is given on M2M, service delivery platforms, and cloud computing (including virtualization). There are currently two approaches to the use of clouds as service delivery platforms. The first approach simply leverages the storage and processing power of cloud fabrics such as Eucalyptus. On the other hand, the second approach epitomized by the work on virtual sensor networks focuses on the efficient use of M2M resource through virtualization, the ultimate goal being the offering of M2M infrastructure as IaaS.

Participatory Sensing: Crowdsourcing Data from Mobile Smartphones in Urban Spaces
» Salil Kanhere | University of New South Wales, Australia

The recent wave of sensor-rich, Internet-enabled, smart mobile devices such as the Apple iPhone has opened the door for a novel paradigm for monitoring the urban landscape known as participatory sensing. Using this paradigm, ordinary citizens can collect multi-modal data streams (e.g., audio, video, sound, location, etc) from the surrounding environment using their mobile devices and share the same using existing communication infrastructure (e.g., 3G or WiFi). The data contributed from multiple participants can be combined to build a spatiotemporal view of the phenomenon of interest and also to extract important community statistics. Given the ubiquity of mobile phones and the high density of people in metropolitan areas, participatory sensing can achieve an unprecedented level of coverage in both space and time for observing events of interest in urban spaces. This tutorial will provide a comprehensive overview of this exciting new sensing paradigm and discuss the associated research challenges. Specifically, the tutorial will cover the following topics - (i) Overview and motivation of the new paradigm of participatory sensing, (ii) A summary of new exciting applications (iii) A detailed discussion on the key research challenges including: participatory sensing architectures, trustworthiness and privacy, dealing with insufficient samples, activity and context inference, system design issue, (iv) Conclusions and future directions.
