Energy-Efficient Multihop Routing Framework for Cluster-based Agricultural Internet of Things (CA-IoT)

Abstract

In this paper, we propose an energy-efficient multihop routing framework that is based on the total communication costs metric (E TER,min ), and implement it in a multihop clustering-based Agricultural Internet of Things (CA-IoT) network. Furthermore, an impact assessment based on the network lifespan or power-savings, scalability/adaptability, and coverage stability metrics is performed on the proposed framework. As the power-constrained CA-IoT network scales, a more realistic, energy-efficient multihop route-actuating framework becomes imperative for achieving the stated desired metrics in the new-age IoT applications. The proposed framework defined the desired location and power consumption specifications of IoT devices. Sample simulation results show that our framework ensures higher network energy-savings, scalability, and network stability span compared to single-hop routing schemes under similar conditions.
