摘要

随着物联网(IoT)应用的迅速扩展,有必要全面了解网络配置,以应对各种使用案例中的独特挑战。本文深入分析了三种物联网网络拓扑结构:线性链、结构树和动态过渡网络,每种拓扑结构都旨在满足工业自动化、家庭自动化和环境监测的特定要求。通过模拟和硬件实验评估了关键性能指标,包括往返时间(RTT)、服务器处理时间(SPT)和功耗。此外,本研究还引入了一种增强型 UDP 协议,该协议具有确认机制和功耗评估功能,旨在提高数据传输的可靠性,使其优于标准 UDP 协议。为了比较标准 UDP 协议和增强型 UDP 协议的性能,在硬件实验中专门测量了数据包丢失情况。研究结果表明,与标准 UDP 相比,增强型 UDP 能显著减少数据包丢失,提高动态和结构化网络中的数据传输可靠性,但其代价是额外的处理过程导致功耗略有增加。在网络拓扑性能方面,线性链拓扑处理稳定,但 RTT 较高,适合隧道监控等应用;结构树拓扑能耗低,通信速度快,是家庭自动化的理想选择;动态过渡网络适合工业自动导引车 (AGV),但在自适应路由选择方面遇到了挑战。这些见解为优化通信协议和网络配置提供了指导,从而实现更高效、更可靠的物联网部署。

Performance Evaluation of UDP-Based Data Transmission with Acknowledgment for Various Network Topologies in IoT Environments
The rapid expansion of Internet-of-Things (IoT) applications necessitates a thorough understanding of network configurations to address unique challenges across various use cases. This paper presents an in-depth analysis of three IoT network topologies: linear chain, structured tree, and dynamic transition networks, each designed to meet the specific requirements of industrial automation, home automation, and environmental monitoring. Key performance metrics, including round-trip time (RTT), server processing time (SPT), and power consumption, are evaluated through both simulation and hardware experiments. Additionally, this study introduces an enhanced UDP protocol featuring an acknowledgment mechanism and a power consumption evaluation, aiming to improve data transmission reliability over the standard UDP protocol. Packet loss is specifically measured in hardware experiments to compare the performance of standard and enhanced UDP protocols. The findings show that the enhanced UDP significantly reduces packet loss compared to the standard UDP, enhancing data delivery reliability across dynamic and structured networks, though it comes at the cost of slightly higher power consumption due to additional processing. For network topology performance, the linear chain topology provides stable processing but higher RTT, making it suitable for applications such as tunnel monitoring; the structured tree topology offers low energy consumption and fast communication, ideal for home automation; and the dynamic transition network, suited for industrial Automated Guided Vehicles (AGVs), encounters challenges with adaptive routing. These insights guide the optimization of communication protocols and network configurations for more efficient and reliable IoT deployments.
