Abstract Denial of service is characterized by the explicit attempt of the attackers to prevent legitimate user services. With the distributed denial-of-service multiple machines are deployed machines in the network. The denial of service affects the packet stream with the key resources rendering the legitimate clients to provide the ultimate access to the arbitrary damage. In DDoS environment the attacks are distributed with the largescale attempt the malicious users for the enormous number of network packets. The proposed model uses the weighted adaptive cache clustering (WACC) model for the denial of service flooding attacks in the network. The proposed WACC model uses the adaptive model in the estimation of the attack scenario in the network. The proposed WACC model exhibits the reduced False positive Rate, throughput and response rate. The proposed WACC model achieves the maximal delay of 35.41 ms while the conventional TEV achieves the maximal packet delay of 38.15ms and EMC provides the 42.69ms. The estimation expressed that the proposed WACC model achieves a higher throughput value of 88.35%. The analysis concluded that the proposed WACC model achieves improved performance for the prevention of denial-of-services flooding attacks.
