Digitalization of production processes is rather important to improve the industrial ecosystem. When implemented, such digitalization has positive impacts in value chain, from helping choose best raw materials providing high quality products. However, adoption technologies settings may not be straightforward given associated challenges. To mitigate this inherent reluctance and encourage implementation Industry 4.0 vision, we developed Wireless Gateway for Industrial IoT (WGW4IIoT) that...

This paper proposes a framework that optimizes network slicing provisioning in over‐the‐top (OTT) scenarios, by reducing occupied resources of slices from where the User Equipment (UE) handovers from. To achieve this, leverages an existing Software Defined Networking (SDN)‐based UE virtualization scheme, which allows to instantiate cloud representation physical device and its current connectivity context. scheme was extended with ability anchor UE's datapath mask underlying single end‐to‐end...

Currently, information security is a significant challenge in the era because businesses store critical databases. Therefore, databases need to be secure component of an enterprise.
