With　the　improvement　of　network　transmission　level　and　hardware　storage　and　computing　capacity,　the　Internet　of　Things　(IoT)　has　been　rapidly　developed,　and　its　application　has　attracted　extensive　attention.　As　an　innovative　application　of　Internet　of　Things　technology　in　the　field　of　industrial　automation　production,　the　Industrial　Internet　of　Things　includes　technologies　such　as　edge　computing,　big　data　analysis　and　intelligent　sensing,　which　greatly　improves　production　efficiency　and　reduces　management　costs.　At　present,　Industrial　Internet　of　Things　(IIoT)　has　become　the　key　competitiveness　of　the　country.　However,　the　heterogeneity　of　equipment,　the　limitation　of　resources　and　the　low　security　of　data　have　greatly　hindered　the　development　of　IIoT.　Therefore,　in　terms　of　ensuring　efficient　energy　utilization,　a　trusted　relay　routing　mechanism　for　optimizing　chain　performance　based　on　multi-attribute　comprehensive　evaluation　for　the　IIoT　is　proposed.　It　is　an　improvement　of　the　low-energy　adaptive　clustering　hierarchy　(LEACH)　algorithm　(a　cluster　routing　protocol　that　is　mainly　used　in　WSN)　to　improve　the　network＇s　data　security　transmission,　energy　efficiency　and　load　balancing　characteristics.　©　2023,　The　Author(s),　under　exclusive　licence　to　Springer-Verlag　London　Ltd.,　part　of　Springer　Nature.
