The energy efficiency paradigm associated with Wireless Sensor Networks (WSNs) and the Internet of Things (IoT) is a major bottleneck for the development of related technologies. Recently, we have seen massive deployments of wireless sensor networks (WSNs) in the physical environment to gather data to better understand the environment. WSNs are composed of a distributed network of similar, low powered, low storage, low processing, and low wireless communication range nodes. The nodes are battery operated with a limited lifespan and therefore replacing the batteries becomes a cumbersome process. On the other hand, an increasing number of nodes (things) are being connected to the Internet as they become more advanced, compact, and affordable. The network of Internet-connected things is generally referred to as the Internet of Things (IoT). The IoT ecosystem includes a wide range of devices with heterogeneous networking, computing, and storage capabilities. IoT enables the exchange of various types of information (e.g., sensor data, multimedia data) between the things. The things associated with IoT range from sensors, actuators, and mobile phones to humans, vehicles, and so on. Again, the main limiting factor for IoT is battery-operated things. The batteries need to be replaced after some time. Therefore, energy harvesting from the environment to power the nodes is a better option compared to battery-powered nodes/things along with effective energy management schemes.
