摘要

用于处理患者数据的网关设备在为连接的医疗保健系统中的患者监测和协助提供准确和关键的护理方面发挥着关键作用。远程广域网（LoRaWAN）是一种广域网协议，用于在使用网关设备的医疗保健网络中的患者健康传感器、监视器和健康辅助服务之间提供低功耗、无缝通信。研究工作的目的是通过采用LoRaWAN的自适应设备放置策略来实现网关的优化，从而提高网络性能。该策略是一个多目标优化，包括覆盖最大化、连通性优化和能量最小化，以提高网络性能。利用omnet++框架对LoRa （FLoRa）的仿真结果验证了网关放置策略。通过基于网关放置策略观察到的关键指标结果验证了网络性能的改进，导致平均能耗为4.44 mJ，分组传递率（PDR）为69%，吞吐量达到481 bps。

Optimizing IoMT network performance using gateway placement

Gateway Device placement for processing patient data, plays a pivotal role in providing accurate and critical care for patient monitoring and assistance in a connected healthcare system. Long Range Wide Area Network (LoRaWAN) is a wide area network protocol used in providing low-power, seamless communication between the patient health sensors, monitors and the health assistance services in a healthcare network using gateway devices. Objective of the research work is to achieve optimization in the gateway by an adaptive device placement strategy using LoRaWAN thereby improving the network performance. The strategy is a multi-objective optimization, which includes Coverage Maximization, connectivity Optimization, and Energy Minimization for improving the network performance. The gateway placement strategy is verified with the simulation results obtained from Omnet++ Framework for LoRa (FLoRa). The network performance improvement is verified with key metric results observed based on the gateway placement strategy, resulted in Average Energy Consumption being 4.44 mJ, Packet Delivery Ratio (PDR) at 69 %, and Throughput reaching to 481 bps.
