Haitao Wang, Lihua Song, Hui Chen, Yan Li, Shicai Zhu · 2013
Cognitive Radio (CR) and Cognitive Network (CN) can optimize system objects by dynamically assigning network resource and adjusting network operations in terms of network environments and conditions.So these two cognitive technologies are very suitable for building emergency communication system to improve resource utilization ratio and enhancing dependability and availability of communication services.In this paper, background requirements of constructing cognitive emergency communication systems are expatiated and technical traits of CR and CN are introduced.Then, network architecture and model of cognitive emergency communication system are proposed.In addition, CPE and SAN are explained too.In the end, several application scenarios and future works of cognitive emergency communication network are discussed and prospected.
