低功耗蓝牙（BLE）是一种低功耗个人区域无线网络技术，对于大规模物联网（IoT）部署越来越重要。通过设计，BLE局限于小区域和简单的网络拓扑。此外，它不是为动态实施策略和访问控制而设计的。这些限制是基于BLE的IoT服务部署的障碍，其中用于服务的IoT设备可能需要被分组到跨越相当大的地理区域的网络切片中，并且具有强的每切片策略执行。本文提出了一种用于创建广域物联网服务切片的架构，该架构在边缘利用BLE设备。为此，我们引入了一个SDN控制的“交换机节点”，称为BLE服务交换机（BLESS），它透明地插入两个通信BLE设备之间。它可以由中央控制器在服务层进行编程，并实现设备之间基于策略的灵活切换。我们描述了BLESS的设计，并通过几个实际的用例来说明它的实用性。
Bluetooth Low Energy (BLE) is a low-energy personal area wireless network technology that is of increasing importance for large-scale Internet of Things (IoT) deployment. By design, BLE is localized to small regions and to simple network topologies. Moreover, it is not designed for dynamic enforcement of policy and access controls. These limitations are impediments to BLE based IoT service deployment, where IoT devices for a service may need to be grouped into a network slice spanning a sizable geographic region and with strong per-slice policy enforcement. This paper presents an architecture for creating wide-area IoT service slices which utilize BLE devices at the edge. For this, we introduce an SDN-controlled “switch node”, called BLE service switch (BLESS) that is transparently inserted between two communicating BLE devices. It can be programmed at the service layer by a central controller and enables flexible, policy-based switching between the devices. We describe the design of BLESS, and illustrate its utility through a few practical use cases.
