Hernâni Delgado Chantre in 5G Month at IC

5G mobile networks are distributed networks based on network function virtualization (NFV) that support a variety of applications with diverse service requirements, namely: ultra-reliable and low latency communication (URLLC), broadband applications (eMBB ) and massive machine type communication (mTC) and large-scale connectivity for Internet of Things (IoT) devices.

One of the main challenges facing infrastructure operators (InP) of 5G mobile networks is the operational cost and distributed management of multi-access edge computing (MECs) and the reliable design of NFV-based networks, as it is of paramount importance to mitigate or minimize malfunctions or failures of virtual network functions (VNFs) that may compromise service level agreements of various network services offered.

The doctoral thesis entitled “Positioning of MECs in 5G Protected Cellular Networks”, by student Hernâni Delgado Chantre and supervised by Prof. Nelson Fonseca, aims to develop algorithms to analyze the impact of the distribution of VNFs on the cost of providing reliability in the 5G network based on NFV as well as investigating the positioning of MECs and network slices in 5G mobile networks protected by different protection schemes. The proposed techniques are evaluated based on various reliability levels, latency requirements, and failure probability. The results show that improved protection schemes are more cost-effective, and that the distribution of VNFs imposes considerable costs on InPs.

Congratulations Hernâni and Prof. Nelson for the research!
