With　regard　to　the　fundamental　problem　of　the　MANET　routing　protocols,　this　paper　according　to　the　campus　mobile　node　behaviour,　aims　to　establish　a　campus　wireless　mobile　model　based　on　AOC　system.　Through　NS-2　simulation　platform　extensive　simulate　result　and　analysis　of　different　mobile　fashion　which　effect　on　the　MANET　routing　protocol　performance:　in　the　aspect　of　Packet　Delivery　Ratio,DSR　and　AODV　both　surpass　95%,　were　not　greatly　affected　by　the　changes　of　node　mobile　rate;　DSDV　and　DSR　closed　to　the　Path　Optimality.
