The invention provides an
Internet of Things-oriented multi-fragment cooperation method, which comprises the following steps of: S1, constructing a dynamic reputation evaluation model, registering an
Internet of Things node, performing performance and behavior evaluation on the node to generate a dynamically updated reputation value, and recording node identity information through chain registration; s2, double-layer gateway nodes are selected based on the reputation value, the double-layer gateway nodes comprise an on-
chip gateway node and a global gateway node, the on-
chip gateway node serves as a fragment communication hub, and the global gateway node coordinates a cross-fragment request; s3, constructing a layered service
directory and realizing cross-fragment service calling, maintaining a local service
directory by an on-
chip gateway node, maintaining a global service
directory by a global gateway node, and positioning and routing a service request through the directory; and S4, verifying a cross-fragment service execution result by adopting a
consensus mechanism, and returning the result through the gateway node.
