The integration of IoT communication technologies such as Low Power Wide Area Networks (LPWAN) is essential in today systems including supply chain, healthcare, autonomous vehicle, etc. In such environments there is an increase in IoT applications that require End Devices (EDs) mobility within similar or heterogeneous LPWAN technologies. Supporting mobility refers to ensure the delivery of data on demand and during movement. In this paper, we investigate the mobility of ED between different LPWAN technologies. We propose a new mobility management solution in LPWAN to achieve continuity of the communication after the link layer technology changes between the ED and the Application Server (AS). This solution is IPv6-based and supports switching between heterogeneous LPWAN networks and technologies. It results in reducing the time required to deliver the data by optimizing the communication routing and saving the bandwidth. The validation of the proposed solution is achieved through the scenarios of ED handovers between LoRaWAN and NB-IoT using simulations as well as experimentation.

如今，在包括供应链，医疗保健，自动驾驶汽车等系统中，低功耗广域网（LPWAN）等物联网通信技术的集成至关重要。在此类环境中，物联网应用的需求日渐增加在类似或异构的LPWAN技术中。支持移动性是指确保按需以及在移动过程中传递数据。在本文中，我们研究了不同LPWAN技术之间ED的移动性。我们在LPWAN中提出了一种新的移动性管理解决方案，以在ED和应用程序服务器（AS）之间的链路层技术发生变化之后实现通信的连续性。该解决方案基于IPv6，并支持在异构LPWAN网络和技术之间进行切换。通过优化通信路由并节省带宽，可以减少传递数据所需的时间。通过在LoRaWAN和NB-IoT之间使用模拟和实验进行ED切换的场景，可以对所提出的解决方案进行验证。
