- 适合低功耗物联网网络研究者参考
大量异构无线网络共享工业、科学和医学（ISM）频段的免许可频谱。这些网络未遵循统一的介质访问规则，且技术规格差异显著。当同时活跃时，彼此产生交叉技术干扰（CTI），其影响不具对称性：高功率或先进传输方案的网络常对资源有限的网络造成严重干扰。这种干扰导致数据包损坏、重传开销、端到端延迟与抖动增加，使网络行为不可预测。本文聚焦基于IEEE 802.15.4标准的低功耗网络，探讨最新在CTI检测、共存与避让机制方面的进展，以及促进异构网络直接通信以协调传输和信道分配的消息方案。
原文摘要 · Abstract (English)
A large number of heterogeneous wireless networks share the unlicensed spectrum designated as the ISM (Industry, Scientific, and Medicine) radio band. These networks do not adhere to a common medium access rule and differ in their specifications considerably. As a result, when concurrently active, they cause cross-technology interference (CTI) on each other. The effect of this interference is not reciprocal, the networks using high transmission power and advanced transmission schemes often causing disproportionate disruptions to those with modest communication and computation resources. CTI corrupts packets, incurs packet retransmission cost, introduces end-to-end latency and jitter, and make networks unpredictable. The purpose of this paper is to closely examine its impact on low-power networks which are based on the IEEE 802.15.4 standard. It discusses latest developments on CTI detection, coexistence and avoidance mechanisms as well on messaging schemes which attempt to enable heterogeneous networks directly communicate with one another to coordinate packet transmission and channel assignment.
