Network slicing

Definition

Network slicing is a technique that allows multiple virtual networks to be created on top of a shared physical infrastructure. This capability is especially relevant in the context of 5G and beyond, as it enables the customization of network resources to meet diverse application requirements, ranging from low latency to high bandwidth. Network slicing is pivotal for optimizing the performance and efficiency of wireless sensor networks (WSNs) by providing dedicated resources for different applications and services.
