The Research of CR-Based Underwater Wireless Network

Abstract

Underwater wireless network (UWN) has been considered as one of the very important technologies for underwater communication, which widely used in scientific research, environmental survey, commercial, military domains, etc. But underwater environmental is complex, water is a worse communication medium than the air, and time-varying in nature. Thus, it is necessary to explore higher communication and network intelligence such as cognitive radio (CR) in UWA. In this paper, a novel environment-adaptive CR-based UWA is proposed. Furthermore, the design of network architecture, cognitive system processing cycle and model of node module are described and discussed.
