Standardization Of Security In Geographic Routing Protocol Using Blockchain And Optimization Based Clustering Technique

Abstract

A wireless sensor network (WSN) is a collection of nodes linked via wireless link. Environmental variables, adversary assaults, battery power loss, and other reasons can contribute to node failure. Recovery after a node failure is difficult and it necessitates a robust node recovery scheme. In this research, a Blockchain-based node recovery strategy and an optimum cluster head (CH) selection with the assistance of Bacterial Foraging Algorithm (BFA) for WSNs is suggested. It's a reliable and quick algorithm for solving discrete optimisation issues. The recovery of failed node is initiated based on node’s degree. The main function of proposed scheme is to discover the failed node that is initiated by the node state (active or inactive) of Cluster Heads (CHs). The recovery procedure for inactive nodes begins in the second phase. The major goal of this phase is to recover the failing CH, which will then result in the active statuses of its member nodes that are restored. Furthermore, a security analysis is carried out to guarantee that the suggested system is secure. The simulation results demonstrate the effectiveness of the suggested model.
