Introduction to Green Internet of Things Sensor Networks

Abstract

The escalating rate of deployments of real-life applications of wireless sensor networks (WSNs) has been observed over the years. Research has identified these WSNs as networks that operate with more limited energy compared to other wireless networks. Power consumption is the Achilles’ heel of the network lifetime in these networks. Most of the power is lost during the transmission of information from a source to the destination. Various approaches that aim to minimize power loss to extend the network lifetime have been proposed. Communication between sensor networks cannot be achieved physically through sensor nodes, and, therefore, there is a need for an Internet-based network (Network to Networks communications). In this chapter, we emphasized on the “Green” IoT technologies that make it environmentally friendly by focusing on optimization of data centers through techniques of sharing infrastructure, which leads to increased energy efficiency and lower cost of operation. The inexpensive, low powered sensors will expand the application of IoT to even smaller objects in any kind of environment at affordable prices. It is also anticipated that combining Energy Harvesting, Communications Techniques, and Data Compression will yield high results that will help to improve the network lifetime of Internet of Things Sensor Networks. Since these networks are suitable for large-scale deployments, large quantities of data are handled during transmission from source to sink. This also includes data that is irrelevant and may add to the energy that is wasted during the transmission of data that eventually results in reducing the network lifetime. The need for a robust and energy-efficient technique to minimize data before transmission and transmit the reduced data along the optimal transmission paths motivated this book.
