The objective of RAN is to effectively manage and utilize the scarce spectrum to provide good connectivity to the end user. Over the past decade, the growth in usage of smartphones and handheld gadgets, as well as the surging adoption of smart vehicles and sensors, has caused a dramatic increase in the wireless traffic to be carried over the network. This traffic can be categorized into distinct use cases having varying requirements in terms of bandwidth, latency, reliability, etc., which are unlikely to be catered for by the current one-size-fits-all network infrastructure. Network Slicing (NS) has emerged as a promising architectural technology for building a highly flexible and dynamic network to meet the extremely diversified needs of use cases. The resulting network is much Plus d'infos

I would like to invite you to my thesis defence that will be held on 06/12/2022 at 14:30 in the thesis room at Hannah Arendt campus (City centre). I would be glad to see your presence. For those who can not attend in person, a BBB link will be sent soon. Abstract: The widespread adoption of 5G cellular technology will evolve as one of the major drivers for the growth of IoT-based applications. In the first part of this thesis, we consider a service provider that launches a smart city service based on IoT data readings: to serve IoT data collected across different locations, the SP dynamically negotiates and re-scales bandwidth and service functions.  Network slicing is becoming the platform of choice for several applications and services. Nowadays, most applications are virtualized to gain flexibility and portability. With network slicing, operators can create multiple network slices, which can be used for different applications with specific requirements. Behind the network slicing, a slice expresses the need to access a precise service type, under a fully qualified set of computing and network requirements. Also, different infrastructure providers charge slicing services depending on specific access technology supported across sites and IoT data collection patterns. Plus d'infos

The thesis defense is scheduled at 2 PM on 28 June at Amphiteater ADA (CERI).  Title: Resource Allocation and Pricing in 5G Network Slicing Abstract: Network slicing is one of the potential technologies to support a higher degree of heterogeneity and flexibility required by next-generation services in 5G networks. In 5G environments, a network slicing is a specific form of virtualisation that allows multiple logical networks (e.g., Mobile Virtual Network Operators (MVNOs)) to run on top of shared physical infrastructure. In emerging 5G mobile technology, network design also incorporates data-centers into their plan to support computation offloading and network function virtualization. Thus, a slice will often comprise different resource types. (e.g., radio resource, CPU, memory, bandwidth). That implies that a heterogeneous set of resources is shared among Slice tenants or MVNOs, and a portion of them is allocated to each slice to support dedicated service to their customers. The core challenge in this context is to determine at once the price of the available of heterogeneous resources and their assignment across different slices. This thesis presents different novel resource allocation and pricing models for 5G  network slicing. First, we devise a flexible sharing mechanism based on a bidding scheme which is Plus d'infos
