The　WiFi　sensor　network　is　a　new　technology　for　The　Internet　of　Things,　it　main　resolve　the　problem　of　informationize,　it　can　collect　thousands　of　sensor　information　by　the　sensors,　and　transform　the　information　by　WiFi　sensor　network.　As　for　the　function　of　WiFi　sensor　network,　it　must　face　to　huge　amounts　of　redundant　data,　in　order　to　deal　with　the　huge　data,　we　have　to　code　a　lot　of　mapping　code,　it　was　a　lot　of　time　and　space.In　this　article,　we　introduce　a　new　method　for　WiFi　sensor　network　management　based　on　runtime　model　instead　of　coding.　Our　method　have　three　steps:　first,　construct　runtime　model　on　WiFi　sensor　device;　second,　merge　the　distributed　runtime　model;　last,　convert　the　Composite　Patterns　Model　to　Application　Scenario　Model.　The　runtime　composite　model　will　help　the　WiFi　sensor　network　to　deal　with　huge　amounts　of　redundant　data.　At　the　end　of　article,　we　apply　our　method　on　an　application　of　enterprise　management　system,　the　results　show　that　our　method　have　high　feasibility　and　effectively.　©　2016　SERSC.
