"M2M in Smart Grid & Smart Cities: Technologies, Standards, and Applications" Presenters: Mischa Dohler, CTTC, Spain (IEEE ComSoc Distinguished Lecturer for 2012 and 2013) Jesús Alonso-Zárate, CTTC, Spain Duration 4 Hours Tutorial on IEEE Tutorial Now Abstract An unprecedented communication paradigm facilitating the connection between a prior unseen number of automated devices is currently gripping both industrial as well as academic communities. Referred to as machine-to-machine (M2M) communication, it is essentially composed of three key ingredients: 1) a wireless end-device, 2) an infrastructure-based or infrastructure-less wireless carrier network, and 3) the back-end server network. This tutorial is focused on the networking part of the architecture, dwelling on the technology required to connect the device domain with the application domain. The gamut of application of M2M is vast, including e.g. consumer electronics, telemetry, e-Health, industrial control, and general means of boosting the usage of existing telecoms infrastructures by offering communications and connectivity at large. However, above all of them, smart grids and smart cities are called to be the killer ones. The main reason for that is the strong support they are receiving from institutions. Both the European Union and the US Government are strongly focusing their ICT research programs towards this revolutionary technology that will make the world smarter, more energy efficient, and less dependent on natural energy resources. This means that both academia and industry will strongly bet for an emerging paradigm that still has many challenges to be solved. Indeed, market prospects of M2M are very encouraging, which was estimated at €20bn in 2005 already and is expected to reach €200bn in Q4 2010 connecting more than 100bn communicating devices. The aim of this tutorial is to provide a detailed technical insight into latest key aspects of M2M networks, with particular application to smart cities and smart grids. We will dig into the technical details of the technology required to provide such applications. Global initiatives working on the M2M paradigm agree on the fact that a combination of cellular and short-range capillary networks will be the most effective solution to provide low-cost and low-energy M2M networks. Therefore, in this tutorial we will review the protocol stack required to support M2M traffic into short-range networks; from the PHY layer, to the Application layer. In addition, we will review existing standards for cellular communications, and we will discuss how new generations (LTE-A) will be suitable for M2M communications. Current activities and trends in standardization bodies will be stressed in the tutorial. Along the entire tutorial, challenges and open issued will be identified, thus making the material presented in this tutorial useful for industry and inspiring for research worlds. Keywords smart cities, smart grids, machine-to-machine, architecture, embedded designs, cellular designs, capillary networks. Objectives M2M systems bear very specific and unparalleled challenges in both research and development. Prime design drivers here are the need for virtually zero-outage, immediate-response and high-efficiency to support reliable, green, long-living and delay-constrained M2M applications. With no clear winner established so far, two orthogonal approaches have thus commenced to contend for the M2M market, i.e. 1) cellular solutions which rely on wide coverage (GSM, UMTS, LTE, LTE-A, etc.); and 2) purely embedded short-range solutions relying on cheap deployments (low-power WiFi, ultra low-power Bluetooth, Zigbee, etc.). The prime objective of this tutorial is therefore to acquaint an academic and industrial audience with crucial design approaches and architectural elements to facilitate a viable and efficient deployment of said networks."
