A Scalable and Smart Hierarchical Wireless Communication Architecture Based on Network/User Separation

Abstract

Due to the dramatic development of mobile devices and technologies, wireless networks have become a convenient and popular means of accessing the Internet for the public. However, the existing wireless networking techniques still face several fundamental inherent problems, such as network scalability, flexibility, and interoperability. As a result, future wireless communication networking, such as 5G, is expected to address these problems. In this article, we present a hierarchical identifier network, a novel and practical hierarchical network architecture based on the idea of network/user separation and mapping. We performed extensive experiments in a realworld high-mobility scenario to evaluate the proposed wireless network architecture. The results demonstrate that the hierarchical identifier network achieves better performance on scalability, flexibility, and interoperability compared to its existing counterparts.
