The future of wireless mesh network in next-generation communication: a perspective overview

Abstract

Wireless mesh network (WMN) which evolves from ad-hoc network is a type of self-healing, self-configuration, and multi-hop wireless network. Without expensive and fixed base stations, WMN can be established fast, easily, and flexibly with low cost. With the fast development of wireless communication, the required data rate and amount increase. As WMN can always provide broad communication access with better scalability, flexibility, and robustness, WMN can still play an important role in future and can bring a wide range of applications in next-generation communication. From the beginning till now, the focus of WMN transfers from sparse connection to intelligent dense networking. The wireless network in future will be more complex with different demands. Considering the features of WMN, this paper provides an overview of WMN from the point of view of next-generation communication. The application scenes including space-air-ground integrated network, Internet of Things, and edge computing are provided. When deploying WMN, the technologies suitable for the demands in next-generation communication, such as blockchain, software defined networking, network functions virtualization, and machine learning are discussed. Further, the upcoming challenges and opportunities in future are also highlighted.
