MACBT Algorithm: A Two-Factor Security Design

WSN is used in a variety of critical environments to monitor certain parameters such as border monitoring systems, among others. If any illegal devices are introduced or inserted into this network, it will result in significant data loss or danger. Several studies have been conducted in this field, including false node detection, encryption, and hostile node identification. If a sensor node becomes contaminated (fake node) but continues to deliver valid data, error recovery can be achieved using the system's physical and analytical redundancy (spatial redundancy). To increase security on wireless sensor networks, several approaches are used, including conditional random field, hidden Markov models (HMMs), SDN gateways, a hybrid model that combines CNF and HMM, and blockchain technology. Currently, blockchain technology has been implemented using encryption algorithms to enhance security.
