Energy-Efficient Networking Solutions for Wireless Sensor Networks: A Systematic Literature Review

Abstract

The Internet of Things (IoT) has become a disruptive force for businesses. Smart grids and homes are just few examples of real world infrastructures made possible by IoT. These infrastructures are composed of networked sensors that collectively create a Wireless Sensor Network.  In Wireless Sensor Networks, energy efficiency is a major concern. Sensor nodes are often deployed to a very hostile environment where harvesting energy is nearly impossible. However, each sensor node in WSN is required to have a lifetime that is long enough to fulfill its application requirements. In this paper, several energy-efficient networking solutions are reviewed. A systematic literature review method is used to select the primary studies to be evaluated. Primary studies showed three energy conservation practices or classifications - duty-cycling, data-driven approach, and mobility-based schemes. It is worth noting that there were no solutions that target the said practices.
