o a central network, using small-cell networks instead [48]. As shown in Fig. 1.45, edge computing use cases may be classified into two major categories, that is, third-party applications and operator applications. The MEC ecosystem is likely to bring significant benefit to the mobile operators and other industries as well as to the consumers that will be able to experience services which need to rely on very accurate localization or high performance in terms of latency and throughput. In other words, MEC will be able to support new IoT services that would not be technically or economically feasible without 5G networks. Several use cases are addressed by MEC and also currently considered as part of next-generation mobile networks. Security and safety have been among the most important verticals for IoT. The advances in technology with an ever-increasing amount of information collected from sensors and high-resolution video cameras create the need for a scalable, flexible, and cost-effective solution to analyze the content in real time. MEC can host the analytics applications close to the source and enable increased reliability, better performance, and significant savings by locally proces- sing large volume of data.

Self-driving cars have been already demonstrated by both traditional automotive and new Internet players, and it is anticipated to make the first autonomous cars commer- cially available in 2020 While the work on future 5G systems is currently being con- ducted by various organizations around the globe, the digitalization in the automotive industry is clearly reflected in the use cases and the requirements coming from this sector. The IoT is a key driver for the next-generation technol
