Security Enhancement in Mobile Ad-Hoc Network Using Novel Data Integrity Based Hash Protection Process

Nowadays, Mobile Ad hoc Networks (MANET) are utilized in numerous applications like disaster management, environmental monitoring, tactical operations, and so on. Usually, the MANET is processed in a wireless movable environment, so it has met several issues like insecurity, packet drop, high execution time, etc. In addition, malicious activities in the communication process have a severe impact on network channels. For that, a robust authentication protocol should be established to limit the attack and protect the data from malicious activities. In this article, a novel Data Integrity based Hash Protection (DIHP) algorithm is developed in Intermediate System to Intermediate System (IS-IS) protocol for securing the data transmission in MANET. In this proposed approach, primarily nodes are developed to transfer the data in the moving environment; hereafter, the encryption process is functioned to encrypt the data. If any attacks are tried to decrypt the data in the network channel, then immediately, the prevention parameter is initiated to prevent the attack. Thus, the data is secured from attacks and provides better communication by reducing the data flow rate. Moreover, the proposed DIHP approach is implemented in the Java platform, and the performance metrics are calculated. Also, the obtained results are validated with prevailing protocols and provide better outcomes. Consequently, the proposed DIHP method has attained 98.97bps throughput and 99.57% packet delivery ratio. Moreover, end-to-end delay is reduced as 2 s while compared with existing techniques. In addition, the developed DHIP has obtained a lower data rate and 0.12 ms transmission rate.
