On the Reliability of LTE Random Access: Performance Bounds for Machine-to-Machine Burst Resolution Time
Mikhail Vilgelm, Sebastian Schiessl, Hussein Al-Zubaidy +2
Random Access Channel (RACH) has been identified as one of the major bottlenecks for accommodating massive number of machine-to-machine (M2M) users in LTE networks, especially for…
Distributed VNF Scaling in Large-scale Datacenters: An ADMM-based Approach
Farzad Tashtarian, Amir Varasteh, Ahmadreza Montazerolghaem +1
Network Functions Virtualization (NFV) is a promising network architecture where network functions are virtualized and decoupled from proprietary hardware. In modern datacenters, u…
Enhancing Cellular M2M Random Access with Binary Countdown Contention Resolution
Mikhail Vilgelm, Sergio Rueda Liñares, Wolfgang Kellerer
Accommodating Machine-to-Machine applications and their requirements is one of the challenges on the way from LTE towards 5G networks. The envisioned high density of devices, along…
Delay Analysis of Multichannel Parallel Contention Tree Algorithms (MP-CTA)
Murat Gürsu, Alberto Martínez Alba, Wolfgang Kellerer
Contention tree algorithm is initially invented as a solution to improve the stable throughput problem of Slotted ALOHA in multiple access schemes. Even though the throughput is st…
Logically Isolated, Actually Unpredictable? Measuring Hypervisor Performance in Multi-Tenant SDNs
Arsany Basta, Andreas Blenk, Wolfgang Kellerer +1
Ideally, by enabling multi-tenancy, network virtualization allows to improve resource utilization, while providing performance isolation: although the underlying resources are shar…
