Abstract

A recent study predicted that in 2020 there will be 50 billion devices connected to the Internet. These devices are not only smartphones and tablets, but also things which are able to perform various operations, such as sensing data and actuating on the external environment. With this perspective, WSNs are highly needed in the Internet of Things (IoT) vision. Since WSN nodes are often equipped with batteries, energy-efficient WSNs is an important goal to achieve. In this chapter, we review and compare different energy-efficient clustering protocols for WSNs. We consider WSNs that are composed of heterogeneous wireless sensor devices (i.e., heterogeneous WSNs) but we also take into account protocols that incorporate various IoT devices such as RFID and with energy-harvesting capability. We describe our novel Rotating Energy-Efficient Clustering for Heterogeneous Devices (REECHD). This is a novel clustering protocol for heterogeneous WSNs. REECHD is compared with the state-of-the-art clustering by using simulation.
