The Internet of Things (IoT) devices gather a plethora of data by sensing and monitoring the surrounding environment. Transmission of collected data from the IoT devices to the cloud through relay nodes is one of the many challenges that arise from IoT systems. Fault tolerance, security, energy consumption and load balancing are all examples of issues revolving around data transmissions. This paper focuses on energy consumption, where a priority-based and energy-efficient routing (PriNergy) method is proposed. The method is based on the routing protocol for low-power and lossy network (RPL) model, which determines routing through contents. Each network slot uses timing patterns when sending data to the destination, while considering network traffic, audio and image data. This technique increases the robustness of the routing protocol and ultimately prevents congestion. Experimental results demonstrate that the proposed PriNergy method reduces overhead on the mesh, end-to-end delay and energy consumption. Moreover, it outperforms one of the most successful routing methods in an IoT environment, namely the quality of service RPL (QRPL).

PriNergy：一种用于物联网系统的基于优先级的节能路由方法

物联网 (IoT) 设备通过感知和监控周围环境来收集大量数据。将收集到的数据从 IoT 设备通过中继节点传输到云端是 IoT 系统面临的众多挑战之一。容错、安全、能源消耗和负载平衡都是围绕数据传输的问题的例子。本文重点关注能源消耗，提出了一种基于优先级和节能的路由（PriNergy）方法。该方法基于低功耗和有损网络 (RPL) 模型的路由协议，该模型通过内容确定路由。每个网络插槽在向目的地发送数据时使用计时模式，同时考虑网络流量、音频和图像数据。这种技术增加了路由协议的健壮性并最终防止拥塞。实验结果表明，所提出的 PriNergy 方法减少了网格开销、端到端延迟和能耗。此外，它优于物联网环境中最成功的路由方法之一，即服务质量 RPL (QRPL)。
