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.

***Comments from listeners at ETFA 2016:

1. The paper should consider efficiency of the proposed scheme in practical environmentS. Additionally, the litimiation of this article is concerned with a communication policy mentioned in the system model.

2. How complex is the work if sensing nodes can communicate with each other?
