Construction of Cognitive Radio Based Emergency Communication System and Application Scenario Analysis
نویسندگان
چکیده
Cognitive Radio (CR) can optimize system objects by dynamically assigning network resource and adjusting network operations in terms of network environments and conditions. So CR technology is very suitable for building emergency communication system to improve resource utilization ratio and enhancing dependability and availability of communication services apparently. In this paper, background requirements of constructing cognitive radio based emergency communication systems are expatiated and technical traits of CR 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.
