Low Power Wide Area Networks (LPWANs) provide an energy efficient, wide-range network service to IoT devices. The Quality of Service (QoS) varies significantly between LPWANs in the licensed and unlicensed band, requiring to choose between cost and performance. Combining LPWANs with a multipath approach could improve the QoS, but existing protocols are unsuitable for LPWAN applications. In this letter a novel Narrowband Bundling Protocol (NBP) is proposed, which is tailored to the characteristics of LPWANs. It improves latency, reliability and coverage of IoT networks by aggregating multiple links. First experiments with a real prototype demonstrate promising QoS improvements.

窄带捆绑协议


低功耗广域网 (LPWAN) 为物联网设备提供节能、广泛的网络服务。授权和非授权频段的 LPWAN 之间的服务质量 (QoS) 差异很大，需要在成本和性能之间进行选择。将 LPWAN 与多路径方法相结合可以提高 QoS，但现有协议不适合 LPWAN 应用。在这封信中，提出了一种新颖的窄带捆绑协议（NBP），该协议是针对 LPWAN 的特点而定制的。它通过聚合多个链路来改善物联网网络的延迟、可靠性和覆盖范围。首次使用真实原型进行的实验展示了有希望的 QoS 改进。
