This book investigates data security approaches in Heterogeneous Communications Networks (HCN). First, the book discusses the urgent need for a decentralized data management architecture in HCN. The book investigates preliminaries and related research to help readers obtain a comprehensive picture of the research topic. Second, the book presents three blockchain-based approaches for data management in HCN: data provenance, data query, and data marketing. Finally, based on the insights and experiences from the presented approaches, the book discusses future research directions.

Mobile communication network enables human-to-human, human-to-machine, and machine-to-machine wireless communications via mobile devices, such as mobile phones, sensors, etc. Nowadays, mobile communication network is playing a vital role in our daily lives by supporting a wide range of mobile services, including entertainment, live meetings, social network, and smart transportation. According to statistics, there are 6.4 billion mobile network subscriptions worldwide in 2022, which is predicted to increase to 7.7 billion in 2028, and mobile users on average spend a few hours on their phone every day. To this end, mobile communication network is also becoming the driving force in economic and societal developments, and attracting more and more attention from researchers, industry, and governmental officers.

From the first generation (1G) to the currently commercialized fifth generation (5G), the architecture of mobile communication network has witnessed a significant evolution. In the early 1G-2G, mainly talk and message services were supported by mobile networks. With the increasing bandwidth and data rate, 3G and 4G Long-term Evolution (LTE) can support image or video transmissions for more convenient human-to-human communications. In 5G, a huge number of Internet of Things devices are deployed, which can reach 15 billion worldwide in 2023. As a result, 5G network has evolved to further support massive human-to-machine and machine-to-machine communications that revolutionizes transportation, production, and education sectors. Future networks will further explore technological advances to provide higher data rate, lower transmission delay, and ultra-reliable connections.
