Just in case, any malevolent nodal point retains minimum of 51% of general computing power, it may be able to exploit the consensus contrivance and disrupt the reliability and dependability of the entire network.
2.7.2 5G Technology
IoT protocols are induced by 5G networks design, precisely at perception as well as network layers [52]. Munoz et al. [53] established that generating 5G, necessitates without its own on progressing acceptance of usual traffic formation in addition to integrate heterogeneous systems from “End to End (E2E)” with suitable cloud assets to deliver E2E IoT and mobile services. The “MIMO (multiple-input and multiple-output)” expertise arranged in 5G and basic supportive of “QoS” and “Quality of user Experience (QoE)” aware services [54, 55].
