This paper presents a machine learning based handover management scheme for LTE to improve the Quality of Experience (QoE) user in presence obstacles. We show that, this scenario, state-of-the-art algorithm is unable select appropriate target cell handover, since it always selects with strongest signal without taking into account perceived QoE after handover. In contrast, our learns from past experience how affected when was done certain eNB. Our performance evaluation shows that proposed...
Network slicing is one of the fundamental tenets Fifth Generation (5G)/Sixth (6G) networks. Deploying slices requires end-to-end (E2E) control services and underlying resources in a network substrate featuring an increasing number stakeholders. Beyond technical difficulties this entails, there long list administrative negotiations among parties that do not necessarily trust each other, which often costly manual processes, including legal construction neutral entities. In context, Blockchain...
