Secure VOIP LTE network for secure transmission using PLRT (Packet Level Restraining Technique) under DDOS Attack

The work presented focuses on escalating the VOLTE-VOIP network protection and proposes various technologies to improve network security, but privacy and reliability remain a severe problem that required to be made stronger and the network system in danger to malicious threats. issues in the broadcast network are exploited to exploit network systems by decreasing their productivity by network attackers. The DDOS attack is part of a variety of attacks. DDOS attacks are powerful attacks, which can appear on the network at any time, the main emphasis of this our work attack is to prevent the clients from using IP spoofing and fake messages which disturb the transmission on voice data packets. our proposed technique PLRT(Packet Level Restraining Technique) finds the origin of the DDOS attack and exclude that node from the network for better communication our proposed technique work better under DDOS attack and produces an improved outcome
