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

Abstract

Research activities have rapidly increased in disaster communications domain. Acritical problem is the provision of communications facility to the disaster victims before rescue teamsarrive; this allows victims to help each other. A novel resource management scheme for clustered adhoc networks (CR-RM) in post-disaster communications is proposed in this paper to address thementioned 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-RMscheme is evaluated for probability of successful transmission and spectrum efficiency
