Since MANETs are mainly composed of lightight devices with limited capabilities, efficiently manage security is crucial to reduce the performance degradation and resources consumption. In particular, Mobile Ad hoc NETworks (MANETs) based on Cooperative Communication (CC) present significant challenges to security issues, as well as issues of network performance and management. Thus the authentication and topology control issues are closely correlated in MANETs and they have significant impacts on throughput. While considering the spam attack in MANET with cooperative communication results low throughput in network. So the proposed secure adaptive distributed topology control algorithm aims at topology control and performs secure self-organization in four phases: anti-node detection, cluster formation, key distribution; and key renewal, to protect against malicious node attacks.
