Abstract

Middleware for IoT (Internet of Things) helps application developers face challenges, such as device heterogeneity, service interoperability, security and scalability. While extensively adopted nowadays, IoT middleware systems are static because, after deployment, updates are only possible by stopping the thing. Therefore, adaptive capabilities can improve existing solutions by allowing their dynamic adaptation to changes in the environmental conditions, evolve provided functionalities, or fix bugs. This paper presents AMoT, an adaptive publish/subscribe middleware for IoT whose design and implementation adopt software architecture principles and evolutive adaptation mechanisms. The experimental evaluation of AMoT helps to measure the impact of the proposed adaptation mechanisms while also comparing the performance of AMoT with a widely adopted MQTT (Message Queuing Telemetry Transport) based middleware. In the end, adaptation has an acceptable performance cost and the advantage of tunning the middleware functionality at runtime.
自适应中间件
IoT(物联网)中间件帮助应用程序开发人员应对挑战,如设备异构、服务互操作性、安全性和可扩展性。虽然现在被广泛采用,但物联网中间件系统是静态的,因为在部署之后,更新只能通过停止事物来实现。因此,自适应功能可以通过允许现有解决方案动态适应环境条件的变化、发展提供的功能或修复错误来改进现有解决方案。提出了一种采用软件架构原理和进化适应机制的物联网自适应发布/订阅中间件AMoT。AMoT的实验评估有助于度量所提议的自适应机制的影响,同时还将AMoT的性能与广泛采用的基于MQTT(消息队列遥测传输)的中间件进行比较。最后,自适应具有可接受的性能成本和在运行时调优中间件功能的优势。
