The interest covers all aspects on NGN from the global standards, architecture and services. The management of services provided in the NGN environment has posed great challenges due to the heterogeneity of the service protocols, service requirements and specifications and service functionalities. The research proposes enhancement of the automated service management through embedding the semantic service descriptions that can be referenced to the service ontology for service creation and management into the Next Generation Network, which will become Semantic Next Generation Network (SNGN).展开更多

Therefore, the definition of IoT and its emergence were discussed and organized around the timeline of Internet development phases demonstrating that IoT has been a need that has accompanied the presence of the Internet since its early stages, and then its growth and impact were discussed and highlighted with estimates and numbers. On the technical side, each of the following groups, IoT components, protocols, and architectures, was defined, discussed, and grouped in such a way that their intergroup organization, as well as their placement and contribution to the overall ecosystem, was highlighted. This, in addition to the various examples mentioned throughout the discussion, will provide the reader with a better understanding of the Internet of Things and how deeply it has become entwined in our daily lives and routines as a result of its numerous applications.展开更多
