286  From smart grid to internet of energy


               Security requirements play a vital role in the operation of WSN, but it should
            not impair bandwidth, availability, and data transmission reliability, which are
            essential QoS indicators. The QoS is a remarkable research area in the context
            of IoT and WSN studies. The QoS researches have defined two fundamental
            perspectives as individual QoS and collective QoS in recent years. In individual
            QoS, applications require particular features for sensor types and numbers. On
            the other hand, the communication and delivery parameters of each sensor by
            oneself are not cared but the corresponding requirements are considered.


            7.5 IoT applications in smart grid
            IoT is a widespread and complex communication infrastructure itself. The sys-
            tem is based on acquisition, processing, transmission, and storage of data in
            secure, reliable and efficient way. On the other hand, smart grid presents many
            novel technologies at the generation, transmission, distribution, and consump-
            tion levels as well as IoT. In one hand, the knowledge society demands to know
            the recent situation of any technology related to their life instantly, and to man-
            age their own microgrid sources, home appliances, EVs, to monitor the daily
            statistics on services such as electricity, gas, and water. On the other hand, ser-
            vice providers require ICT technologies for management, monitoring, detection
            of the faults and troubleshoot aims. The most recent communication structure is
            being improved by using IoT technology in smart grid applications. The infra-
            structure is comprised by low-power and low-cost microprocessors, digital
            communication systems including security and reliability supports, and adapt-
            able communication layer and protocol structures to interact among numerous
            different hardware and software technologies. The improvements seen on IoT
            have attracted attention of smart grid operators and developers. The preliminary
            communication methods and network infrastructures that have been widely
            used in smart grid are being updated to meet the requirements of IoT to benefit
            from cost and power efficient communication technologies. The easy access
            opportunity of IoT with a widespread mobile device support enables to imple-
            ment infrastructures for monitoring sensors, actuators, surveillance cameras,
            smart cities, smart home applications, medical applications, smart microgrid
            structures, and security issues. Minoli et al. define IoT applications for smart
            city with five key areas as energy, water, mobility, buildings, and governments
            from a system perspective [6]. The IoT applications that are improved in the
            context of smart grid have been categorized into five prominent titles as smart
            cities, smart home applications, energy harvesting issues, smart sensor net-
            works, and monitoring and metering topics.
               In the complex and heterogeneous ICT environment, IoT provides several
            communication technologies and network types. Some of them has been pre-
            sented in the previous sections as communication infrastructures, services, pro-
            tocols, security and privacy, and sensor networks. Furthermore, we have
            comprehensively presented IoT communications and networks improving the
            conventional and degraded ICT infrastructures by transforming to IoT-based
