###### Abstract
In addition to encoding at the content provider, network coding can support secondary encoding at intermediate nodes, reducing the dependence on original data and enhancing the transmission reliability. Edge nodes can acquire arbitrary encoded blocks from the providers or intermediate nodes. Once enough linearly independent encoded blocks have been collected, the edge nodes can decode and restore the original content. This encoding and decoding process is independent of the content providers and encoded blocks' acquisition paths. In MIN-IIoT, identity authentication prevents the risk of data leakage caused by the encoding and decoding of intermediate routers. In order to reduce the pressure of the intermediate nodes without destroying the security characteristics of the multi-identifier network, we only perform the decoding operations on the edge nodes. Edge nodes can provide services for the connected terminal nodes, which can avoid redundant encoding and decoding operations at the terminal nodes and solve the problem of insufficient storage and computing resources on the terminal nodes. The integration of network coding and edge computing is particularly suitable for scenarios with solid mobility and real-time requirements, such as Internet of Vehicles. This paper mainly focuses on content acquisition with the integration of edge computing and network coding in the Industrial Internet. It solves the problem of idle links and redundant transmission in multipath forwarding through name identifiers. A multipath forwarding strategy is proposed based on the identities of content requesters. Then, a multi-edge node cooperation method is designed to support the content requester movement. In summary, the essential contributions of this paper are listed as follows:  
* An identity-differentiated content acquisition with network coding and edge computing multipath forwarding strategy, IDEANE, is designed to differentiate content requests through identity identifiers in MIN-IIoT. The hash values of the identity identifiers of the content request initiators are encapsulated in the request interest messages and mapped to the PIT and CS of the intermediate nodes. The intermediate nodes can avoid redundant responses to interest messages requesting the same encoded blocks by identifying the content requesters' identities. In addition, they can ensure that the interest messages from the same content requester, aggregated through multiple paths, can acquire as many linearly independent encoded blocks as possible. At the same time, in order not to degrade the security performance of the MIN-IIoT system, the encoded blocks are only verified at the intermediate nodes without secondary encoding, thus reducing the network transmission delay. * In the event that the content requester moves, the encoding and decoding tasks are offloaded to multiple edge nodes. The requests for the encoded blocks and the restoration of the original blocks are completed through the cooperation of numerous edge nodes. The request transmission delay is reduced, and redundant data transmission is avoided. * Simulation results show that IDEANE can reduce the transmission delay of content requests compared with NetCodCCN [13], which encodes and decodes data blocks in intermediate nodes. At the same time, it can quickly meet the content requirements of mobile requesters through the collaboration of multiple edge nodes. The remainder of this paper is organized as follows. Section 2 reviews the related work on image anomaly detection. A detailed description of the identity-differentiated content acquisition strategy is given in Section 3. We propose the collaboration algorithm for multiple edge nodes for content requesters' mobility in Section 4. Section 5 presents the corresponding experiments and analyzes the simulation results. Section 7 concludes the paper and discusses future research.
