摘要物联网（Internet of Things， IoT）对广域通信提出了高效、可靠、低功耗的要求，因此窄带物联网（Narrow Band Internet of Things， NB-IoT）技术应运而生，其通过优化网络升级和降低成本，实现了广泛分布式的设备连接。可靠数据报协议（Reliable User Datagram Protocol， RUDP）对传统UDP进行增强，旨在提供低延迟通信和可靠保证，其中快速可靠传输协议（KCP）因其轻量和灵活被广泛采用。为满足窄带物联网在分布式复杂场景下的传输需求，本文优化了KCP传输逻辑，设计发布-订阅、请求-响应两种模式满足应用层需求，并引入了心跳检测和选举机制，以提升系统的稳定性和容错性。
Abstract：The Internet of Things (IoT) demands high efficiency, reliability, and low power consumption for wide-area communication. Narrowband Internet of Things (NB-IoT) technology was invented, allowing widespread distributed device connectivity through optimised network upgrades and cost reductions. The Reliable User Datagram Protocol (RUDP) is an enhancement of traditional UDP, enabling low latency communication and reliable assurance, with its KCP protocol widely adopted due to its lightweight and flexibility. To meet the transmission requirements of narrowband IoT in complex distributed scenarios, this paper optimised the KCP protocol transmission logic and designed publish-subscribe and request-response modes to satisfy application layer requirements. It introduced heartbeat detection and election mechanisms to enhance system stability and fault tolerance.
