An Image Hashing-Based Authentication and Secure Group Communication Scheme for IoT-Enabled MANETs

Mobile ad hoc networks (MANETs) play a highly significant role in the Internet of Things (IoT) for managing node mobility. MANET opens pathway different IoT-based communication systems with effective abilities variety applications several domains. In systems, it provides self-formation and self-connection networks. A key advantage MANETs is that any device or can freely join leave network; however, this makes vulnerable to security attacks. Thus, authentication plays an essential protecting network system from Consequently, secure important prerequisite nodes MANETs. The main problem moving one group another may be attacked on way by misleading neighboring group. To address this, paper, we present mechanism based image hashing where administrator allows crosschecking identity soldier (i.e., node) joining We propose migration algorithms involved ensure identification. simulation tool NS-2 employed conduct extensive simulations extracting results trace files. demonstrate effectiveness proposed scheme memory storage overhead computational cost. our scheme, attack detected effectively also robust assurance.
