Real Time Trading Of Mobile Resources In Beyond 5G Systems

5G is expected to offer download speeds as high as 1 GBps and latency lower than 10 ms that lead to the need for enormous investments. However, many small operators simply do not possess the necessary revenue in order to deploy the required infrastructure, while the rich operators are unwilling ...

Caching to the Sky: Proactive Deployment of Cache-enabled SBSs for Cellular-Connected UAVs

Enhancing LTE support for aerial users has become the study focus of recent 3rd Generation Partnership Project (3GPP) standardizations due to their high maneuverability and flexibility for on-demand deployment. A question arises: how to serve aerial users using LTE network deployments with base station (BS) antennas targeting terrestrial coverage. In ...

ClickNF: a Modular Stack for Network Function Composition

Network function virtualization calls for the replacement of specialized equipment and monolithic software deployments by functionally equivalent but leaner modular software implementations. Server-side network functions developers could especially benefit from the existence of a highly customizable yet scalable framework for the rapid design of network applications. However, balancing the conflicting ...

Cross Link Interference Suppression By Orthogonal Projector in 5G Dynamic-TDD URLLC Systems

Dynamic time division duplexing (TDD) is envisioned as a vital transmission technology of the 5G new radio, due to its reciprocal propagation characteristics. However, the potential cross link interference (CLI) imposes a fundamental limitation against the feasibility of the ultra-reliable and low latency communications (URLLC) in dynamic-TDD systems. In this ...

End-to-End Network Slice Resource Allocation for 5G Mobile Edge Computing

Mobile Edge Computing (MEC) is a key feature in future 5G mobile networks. It enables, low latency services, by bringing them closer towards the users. In 5G also a new logical network architecture providing isolated logical Network Slices (NSLs) is introduced. This necessitates an initial capacity planning and allocation of ...

Automatic Inference of Cloud Application Performance Degradation

In order for a cloud operator to make effective decisions with respect to horizontal scaling, migration, and root cause analysis, current cloud orchestration tools often need to monitor application or service-level metrics, such as latency (response time) or throughput. The interpretation of these metrics often requires significant experience (and expertise) ...

An Efficient Model for Mobile Network Slice Embedding under Resource Uncertainty

The fifth generation (5G) of mobile networks will support several new use cases, like the Internet of Things (IoT), massive Machine Type Communication (mMTC) and Ultra- Reliable and Low Latency Communication (URLLC) as well as significant improvements of the conventional Mobile Broadband (MBB) use case. End-to-end network slicing is a ...
