COGNITIVE RADIO FOR RESOURCE MANAGEMENT FOR CLUSTERED AD HOC NETWORKS IN POST-DISASTER COMMUNICATIONS

Research activities have rapidly increased in disaster communications domain. A critical problem is the provision of communications facility to the disaster victims before rescue teams arrive; this allows victims to help each other. A novel resource management scheme for clustered ad hoc networks (CR-RM) in post-disaster communications is proposed in this paper to address the mentioned problem. Two disaster scenarios are presented, depending on the severity of disaster. A 3- tier conceptual mode for spectrum sharing is also proposed. At the end the performance of CR-RM scheme is evaluated for probability of successful transmission and spectrum efficiency.
