Smart Technologies with Wireless Sensor Networks

Abstract

In recent years, the studies in inter-devices communication (M2M) which is considered to be the Internet, ecosystem of the objects have accelerated in line with the developments in mobile communication technologies. This way, development of systems making human lives easier in smart environment, smart agriculture, smart grid fields with monitoring purposes which can be considered among M2M implementations is now possible. These systems can be developed with sensor node platform which can detect and communicate. Wireless Sensor Networks (WSN) consists of these sensor nodes containing simple processors, low power consuming antennas and various detectors. As the sensor networks do not require wired communication infrastructure, they can easily and inexpensively be formed with no harm to the environment. The sensor nodes have the ability to store and process data locally thanks to the software and hardware structure they have. The fact that they can get in contact with each other enables them to collaborate in performing complicated tasks along with exchanging information. As the communication means have low power consumption, it ensures that the life of the sensor nodes is long. The fact, too, that the nodes are programmable after being placed in the medium provides greater advantages. Because of the low cost and flexibility in use, the wireless sensor nodes are convenient to be used in many industrial and environmental applications. In this study, -how to develop smart environment, smart agriculture, smart grid with WSN-is analyzed.

Industry 4.0: Challenges, Opportunities, and Strategic Solutions for Bangladesh

“…Finally, the fourth industrial revolution, a brainchild of Germany, has started integration of traditional manufacturing processes with cyber-physical production systems (Aulbur, CJ, & Bigghe, 2016;Du et al, 2017;Hofmann & Rüsch, 2017). Due to technological enabling this revolution are connecting with the Internet, big data, cloud computing, advanced robotics, artificial intelligence, new materials, new additive manufacturing technologies (Anderl, 2015;Becker & Stern, 2016;Dener & Bostancıoğlu, 2015;Faller & Feldmüller, 2015;Gokalp et al, 2016;Gorecky et al, 2014;Ji et al, 2014). Moreover, the Big data technologies adopted in industry 4.0 for collecting, processing and analyzing large, unstructured data using smart algorithms for effective real-time competitive business decisions (Anderl, 2015;Faller & Feldmüller, 2015;Gokalp et al, 2016;Hazen et al, 2016;Hofmann & Rüsch, 2017).…”

Integrated Sensor Systems for Smart Cities

“…Apart from the internal connecting of sensors, in the context of smart cities, it is important to externally connect them via wireless network to a central unit that receives and processes data, so they are called wireless sensor networks [8]. That is important because cities are too complex for a single type of sensor needed to satisfy the demands for information necessary for smart management [2].…”

“…In such a way, it is possible to gather various information from multiple sensors at the same location. Because of a big number of sensor nodes that should be installed in a smart city, it is important to pay attention to their size and energy demand [4,8,9,11,15,18,19].…”

“…It can be defined as a modern infrastructure with efficiency and reliability enhanced through automated control, modern communication infrastructure, monitoring and measuring technologies, and advanced energy management based on demand optimization, energy and grid availability etc. [4,5,8,11,24,25].…”

“…Some other problems related to fast-growing cities are lighting systems that cause light pollution in the areas around big cities and big energy consumption, noise pollution that has negative effects on people living and working in cities, and waste management that will represent ever growing problem for cities in the future. In order to solve these problems, today's technology should be used and smart solutions found [8].…”
