T1  - Identification of Signaling Patterns in Mobile IoT Signaling Traffic
T2  - Würzburg Workshop on Next-Generation Communication Networks (WueWoWas'22)
N2  - We attempt to identify sequences of signaling dialogs, to strengthen our understanding of the signaling behavior of IoT devices by examining a dataset containing over 270.000 distinct IoT devices whose signaling traffic has been observed over a 31-day period in a 2G network [4]. We propose a set of rules that allows the assembly of signaling dialogs into so-called sessions in order to identify common patterns and lay the foundation for future research in the areas of traffic modeling and anomaly detection.

T1  - LoRaWAN Network Planning in Smart Environments: Towards Reliability, Scalability, and Cost Reduction
T2  - Würzburg Workshop on Next-Generation Communication Networks (WueWoWas'22)
N2  - The goal in this work is to present a guidance for LoRaWAN planning to improve overall reliability for message transmissions and scalability. At the end, the cost component is discussed. Therefore, a five step approach is presented that helps to plan a LoRaWAN deployment step by step: Based on the device locations, an initial gateway placement is suggested followed by in-depth frequency and channel access planning. After an initial planning phase, updates for channel access and the initial gateway planning is suggested that should also be done periodically during network operation. Since current gateway placement approaches are only studied with random channel access, there is a lot of potential in the cell planning phase. Furthermore, the performance of different channel access approaches is highly related on network load, and thus cell size and sensor density. Last, the influence of different cell planning ideas on expected costs are discussed.

T1  - Affordable Measurement Setups for Networking Device Latency with Sub-Microsecond Accuracy
T2  - Würzburg Workshop on Next-Generation Communication Networks (WueWoWas'22)
N2  - This document presents a networking latency measurement setup that focuses on affordability and universal applicability, and can provide sub-microsecond accuracy. It explains the prerequisites, hardware choices, and considerations to respect during measurement. In addition, it discusses the necessity for exhaustive latency measurements when dealing with high availability and low latency requirements. Preliminary results show that the accuracy is within ±0.02 μs when used with the Intel I350-T2 network adapter.

T1  - DBM: Decentralized Burst Mitigation for Self-Organizing LoRa Deployments
T2  - Würzburg Workshop on Next-Generation Communication Networks (WueWoWas'22)
N2  - This work proposes a novel approach to disperse dense transmission intervals and reduce bursty traffic patterns without the need for centralized control. Furthermore, by keeping the mechanism as close to the Long Range Wide Area Network (LoRaWAN) standard as possible the suggested mechanism can be deployed within existing networks and can even be co-deployed with other devices.
