Strict-Priority Packet Delay in Switches with Transmit-Ring Buffering
Yash Deshpande, Quirin Vogel, Wolfgang Kellerer
Strict Priority (SP) scheduling is widely used at switch egress to provide low-latency service to high-priority (HP) traffic. Existing deterministic and stochastic latency models t…
Improving Network Clock Synchronization by Marking Congestion
Yash Deshpande, Quirin Vogel, Laura Becker +2
Achieving consistent time across devices in distributed systems often involves exchanging timestamped messages over a network. Precise time synchronization is crucial for applicati…
5G Puppeteer: Chaining Hidden Command and Control Channels in 5G Core Networks
Julian Sturm, Daniel Fraunholz, Oliver Zeidler +2
Mobile networks are essential for modern societies. The most recent generation of mobile networks will be even more ubiquitous than previous ones. Therefore, the security of these…
Joint Resource Allocation to Transparently Integrate 5G TDD Uplink with Time-Aware TSN
Laura Becker, Yash Deshpande, Wolfgang Kellerer
To enable mobility in industrial communication systems, the seamless integration of 5G with Time-Sensitive Networking (TSN) is a promising approach. Deterministic communication acr…
Integrating Deterministic Networking with 5G
Yash Deshpande, Philip Diederich, Muhamad Luthfi +3
The rising prevalence of real-time applications that require deterministic communication over mobile networks necessitates the joint operation of both mobile and fixed network comp…
LCDN: Providing Network Determinism with Low-Cost Switches
Philip Diederich, Yash Deshpande, Laura Becker +1
The demands on networks are increasing at a fast pace. In particular, real-time applications have very strict network requirements. However, building a network that hosts real-time…
TwinRAN: Twinning the 5G RAN in Azure Cloud
Yash Deshpande, Eni Sulkaj, Wolfgang Kellerer
The proliferation of 5G technology necessitates advanced network management strategies to ensure optimal performance and reliability. Digital Twin (DT)s have emerged as a promising…
OpenAirLink: Reproducible Wireless Channel Emulation using Software Defined Radios
Yash Deshpande, Xianglong Wang, Wolfgang Kellerer
This paper presents OpenAirLink(OAL), an open-source channel emulator for reproducible testing of wireless scenarios. OAL is implemented on off-the-shelf software-defined radios (S…
A Mobility Analysis of UE-Side Beamforming for Multi-Panel User Equipment with Hand Blockage
Subhyal Bin Iqbal, Salman Nadaf, Umur Karabulut +4
The hand blockage effect of the human hand around the user equipment (UE) is too considerable to be ignored in frequency range 2 (FR2). This adds another layer of complexity to the…
Evaluation of NR-Sidelink for Cooperative Industrial AGVs
Shubhangi Bhadauria, Klea Plaku, Yash Deshpande +1
Industry 4.0 has brought to attention the need for a connected, flexible, and autonomous production environment. The New Radio (NR)-sidelink, which was introduced by the third-gene…
