International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT) - 2016 978-1-4673-9939-5/16/$31.00 ©2016 IEEE A Study of Power Management Techniques for Internet of Things (IoT) Kawaljeet Kaur and Kiranbir Kaur Computer Engineering and Technology Department Guru Nanak Dev University Amritsar, India kawal_gndu@yahoo.com, kiran.dcse@gndu.ac.in Abstract— Internet of Things (IoT) advances when regular ordinary objects have inter-connected microchips inside them. These microchips help stay informed concerning other objects, as well as a significant number of these devices sense their surroundings and report it to different machines and also to the people, so is the application of home environment. The viable significance of the IoT is made conceivable through enabling technologies, for example, Wireless Sensor Networks (WSNs), essentially utilized for detecting operations. In any case, there is a principle prerequisite that makes a wireless sensing perfect for use in the IoT, which is the energy efficiency. Much of the time, the sensing devices are battery-powered, so low-power system is prime requirement. Several mechanisms can be adopted in order to reduce the power consumption while designing the devices that implement a wireless protocol. This paper has presented a comparative study of various energy efficient IoT techniques. Keywords—internet of things; energy efficiency; fuzzy logic controller; bluetooth low energy; wireless sensors I. INTRODUCTION With yearly shipments of large number of micro- controllers that all can exchange data locally or through the Internet, a gigantic variety of "intelligent devices" are empowered. Every one of these devices can be gotten to over the Internet, on account of the fast increment in infrastructure scope and Internet access. This evolution is regularly called the Internet of Things (IoT). The devices that are a part of the network of things are called ''smart things'' that dissimilar to typical devices can interact inside of the communication system in which they are embedded since they have an active role. The devices can be recognized by the accompanying characteristics [6]: • Cost, shape, weight, etc. • Limited resources in terms of processing capacity, memory, energy supply and routing. • Act as actuators to influence or get influenced by environment. The IoT in 2020: guide for the future (2008) characterizes the Internet of things as "things having characters and virtual identities, working in brilliant situations utilizing insightful interfaces to join and convey inside of social, ecological and client settings" [10]. The term IOT was authored by Kevin Ashton, prime supporter of the first Auto-ID Center at MIT, who presented it in 1999. Fig. 1 demonstrates the three distinct stages with which the physical-digital world association happens. 1. Collection stage: It alludes to methodology for detecting the physical environment, gathering continuous physical information and remaking a general impression of it. 2. Transmission stage: It incorporates systems to convey the gathered information to applications and to various outside servers. 3. Processing, management and usage stage: It manages handling and breaking down data streams, forwarding data to applications and services and providing feedback to control Fig. 1.
