Data Receiving Analysis for Secure Routing from Blackhole Attack in a Spontaneous Network Using Blockchain Method

The nodes, or mobile devices, in a dynamic network are continuously moving and are part of a temporary network called the mobile ad hoc Network (MANET). Due to the open network, any node can join or leave the network at any time. So, security is one of the major challenges in MANET. The novel blockchain method is more popular for securing the network from attacks. The attacker nodes are the main issue in secure routing, which disgraces actual routing performance. In this paper, we propose the Blockchain Security Scheme for Blackhole Attack (BSSB) to prevent network from a single as well as multiple blackhole attacks in MANET. The proposed BSSP scheme prevents malicious communication and focuses on gathering malicious node information that is being used to emphasize the intrusion detection and prevention. Routing performance is evaluated in the presence of blackhole attacks, the previous MRREP, and the proposed BSSB approach in MANET. The blockchain method generates a separate block code for every change during routing. In this research, we are not focusing on only single node detection. The proposed scheme can handle the multiple malicious nodes present in the network. The BSSB approach generates a new hash code for every normal change during routing, i.e., for normal packet receiving and forwarding. The performance of the proposed scheme is compared with the MRREP scheme, and the BSSB is showing a better performance in network.
