Authenticated Preambles for Denial of Service Mitigation in LPWANs [PDF]

, 2018
In this article we introduce authentication preambles as a mechanism to mitigate battery exhaustion attacks in LPWAN networks. We focus on the LoRaWAN technology as an exponent of industrial LPWANs. We analyze the impact of DoS attacks in Class B deployments and implement authentication preambles to limit attacker options when forcing nodes to overhear

Bushfire Disaster Monitoring System Using Low Power Wide Area Networks (LPWAN)

Technologies, 2017
Some applications, including disaster monitoring and recovery networks, use low-power wide-area networks (LPWAN). LPWAN sensors capture data bits and transmit them to public carrier networks (e.g., cellular networks) via dedicated gateways.

UniPHY: Unified Physical Layer Security for LPWANs

2025 55th Annual IEEE/IFIP International Conference on Dependable Systems and Networks - Supplemental Volume (DSN-S)
Low-Power Wide Area Networks (LPWANs) play a crucial role in IoT infrastructures, enabling large-scale deployments with minimal power consumption. However, existing security mechanisms primarily operate at higher layers, relying on application-level encryption and centralized authentication schemes.

Layered Chirp Spread Spectrum Modulations for LPWANs

IEEE Transactions on Communications
This article examines two chirp spread spectrum techniques specifically devised for low-power wide-area networks (LPWANs) to optimize energy and spectral efficiency (SE). These methods referred to as layered CSS (LCSS) and layered dual-mode CSS (LDMCSS), involves utilizing multiple layers for multiplexing symbols with varying chirp rates.
