Energy-aware routing scheme in industrial wireless sensor networks for Internet of Things systems

Abstract

This paper proposes an energy-aware routing scheme to enhance the performance of industrial wireless sensor networks (IWSNs) for Internet of Things (IoT) systems. Because of a larger scale and a more complex deployment, to achieve minimal energy consumption for IoT systems is not a simple problem. Additionally, the current works of deploying IWSNs is not compatible to be applied directly into IoT systems. Thus, a hierarchical system framework is deployed in order to promote scalability for IoT elements. Moreover, to minimize energy consumption, the proposed scheme takes transmission distances and residual energy of nodes into account for selecting a relevant cluster head. Then, the data aggregated by cluster heads can be forwarded through the lowest energy consumption path to the sink. The simulation results indicate the potential to either decrease energy consumption and end-to-end delay or prolong network lifetime in IWSNs for IoT systems.
