Machine Learning and Cognitive Communications for 5G and IoT
by Dr. Bijan Jabbari, George Mason University, Electrical and Computer Engineering Department, USA
Abstract: The 5G system is about to be developed and the devices in IoT systems are expected to grow exponentially. There are many challenges that come with this development and growth – one of which is how to efficiently use the available bandwidth. With devices needing to continuously exchange information via shared channels, deciding if, when and how much to transmit in efficient ways becomes important, especially when data stream flows continuously. Since transmission causes a drain on battery power, another challenge is how to design sensing and communication protocols that are energy efficient. The key objective here is to integrate cognitive abilities to these devices and device-to-device interactions to enable coordinated decision making that enhances the efficiency of the overall system. By integrating cognition, we mean enabling the sensors to exploit and mine available (and possibly correlated) data. In this presentation, we review some of the capabilities needed in 5G and IoT and show application of machine learning to make significant energy savings.

Visible Light Communications for 5G-and-Beyond Wireless Telecommunications Networks
by Dr Hoa Le Minh Northumbria University at Newcastle, United Kingdom
Abstract: Artificial general lighting sources are currently evolving through the traditional fluorescent and incandescent sources to the modern energy saving light bulbs and now white light emitting diodes (LEDs). This trend has been spurred on through global awareness of the necessity for reducing the size of our carbon footprint. The introduction of solid state LED lighting has attracted the attention of communications engineer’s worldwide, enabling the achievement of the dual functionality of room illumination whilst simultaneously transmitting wireless data via visible light communication (VLC), or Light Fidelity (LiFi), in optical spectrum regime. Although the existing wireless networks are primely dominated by radio-based technology, the emerging VLC will play increasingly important role in future wireless telecommunications landscape. It is anticipated that both spectrum regimes, radio and optical, will eventually contribute equally for the next network generation, especially in nanocell and picocell network structures. This talk will outline the growth of optical wireless communications including VLC, and present the challenges and roadmap of the technology for the future generation of wireless networks. Keywords— LED, Visible Light Communications, LiFi, Networks
