Aiming　at　the　problem　of　wireless　networking　among　mobile　devices　and　data　backhaul　in　the　IoT　scenario,　this　paper　proposes　a　mobile　Ad　Hoc　network　information　backhaul　system　design.　This　paper　mainly　focuses　the　system　design　especially　software　design　of　the　information　backhaul　network,　including　short-distance　network　communication　design,　mobile　terminal　and　server　interaction　design　and　cloud　display　platform　design.　In　addition,　the　performance　of　the　system　is　evaluated.　The　results　show　that　the　system　has　a　low　packet　loss　rate　and　meets　the　system　design　requirements.
