In　edge　computing　scenarios,　IoT　end　devices　play　a　crucial　role　in　relaying　and　forwarding　data　to　significantly　improve　IoT　network　performance.　However,　traditional　routing　mechanisms　are　not　applicable　to　this　scenario　due　to　differences　in　network　size　and　environment.　Therefore,　it　becomes　crucial　to　establish　an　effective　and　reliable　data　transmission　path　to　ensure　secure　communication　between　devices.　In　this　paper,　we　propose　a　trusted　path　selection　strategy　that　comprehensively　considers　multiple　attributes,　such　as　link　stability　and　edge　cooperation,　and　selects　a　stable　and　secure　data　transmission　path　based　on　the　link　life　cycle,　energy　level,　trust　level,　and　authentication　status.　In　addition,　we　propose　the　Stability-based　On-demand　Multipath　Distance　Vector　(STAOMDV)　protocol　based　on　the　Ad　hoc　AOMDV　protocol.　The　STAOMDV　protocol　implements　the　collection　and　updating　of　link　stability　attributes　during　the　route　discovery　and　maintenance　process.　By　integrating　the　STAOMDV　protocol　with　the　proposed　path　selection　strategy,　a　dependable　and　efficient　routing　mechanism　is　established　for　IoT　networks　in　edge　computing　scenarios.　Simulation　results　validate　that　the　proposed　STAOMDV　model　achieves　a　balance　in　network　energy　consumption　and　extends　the　overall　network　lifespan.
