边缘计算的概念通常与从云中的数据中心到更靠近用户位置的服务器的计算卸载有关，以提高性能。然而，大多数边缘应用程序仍然依赖于云结构，特别是当客户端移动性在用例场景中发挥重要作用时。如果财政资源有限，这可能是一个问题，小企业和预算小的国家就是这种情况。本文是部署UPub的一个步骤，UPub是一个纯粹在Edge中的轻量级基于主题的发布/订阅系统，支持发布者的移动管理。为此，在MQTT之上开发了一个用于发布者切换的协议，同时保持了有序性，一致性和完整性。
The concept of Edge Computing is in general linked to computation offloading from data centers in the Cloud to servers closer to the user's location for performance purposes. However, the majority of Edge applications still rely on Cloud structures, specially when client mobility plays an important role in use-case scenarios. This can be a problem if there is a limitation of financial resources, which is the case of small business and in countries with small budgets. This paper is a step towards the deployment of UPub, a lightweight topic-based publish/subscribe system purely in the Edge with support to mobility management of publishers. To this end, a protocol developed on top of MQTT for publishers handover is presented while properties of Orderedness, Consistency, and Completeness are maintained.
