Abstract

Smart healthcare has been one of the major use cases of the Internet of Things (IoT) and Wireless sensor network (WSN) applications. WSN as a technique for sensing and acquiring data in IoT applications must work upon providing an efficient routing for proper data transfer. One of the fundamental concerns of the routing in WSNs is the energy consumption and the lifetime of sensors, since most of them rely on a battery and neither cable-powered nor frequent battery replacement or recharging are appealing options. The required routing technique must balance the goals: selecting the most reliable minimum energy path when all nodes have high energy and avoiding the low residual energy nodes while supporting mobility. This paper introduces a theoretical framework for RPL (Routing Protocol for Low power and Lossy Networks) based routing protocols whose aim is to provide energy efficiency while taking into account the mobility of sensor nodes in WSNs consisted of both static and mobile nodes. The simulation results indicate that the proposed routing model's Objective Function (OF) gives better performance in comparison to the default OFs in terms of duty cycle, energy consumption and total control overhead, while having a small degradation in the packet delivery ratio.
基于物联网的医疗保健应用的移动性支持的节能路由协议
智能医疗一直是物联网(IoT)和无线传感器网络(WSN)应用的主要用例之一。WSN作为物联网应用中传感和获取数据的技术,必须为正确的数据传输提供有效的路由。无线传感器网络路由的一个基本问题是传感器的能量消耗和寿命,因为它们大多数依赖于电池,无论是电缆供电还是频繁更换电池或充电都不是吸引人的选择。所要求的路由技术必须平衡两个目标:在所有节点能量都较高时选择最可靠的最小能量路径;在支持机动性的同时避免剩余能量较低的节点。本文介绍了基于RPL (Routing Protocol for Low power and Lossy Networks)路由协议的理论框架,其目的是在考虑静态和移动节点组成的wsn中传感器节点的移动性的同时提供能源效率。仿真结果表明,所提路由模型的目标函数(OF)在占空比、能耗和总控制开销方面都优于默认OFs,同时包的投递率也有较小的下降。
