Edge　computing　is　a　promising　technology　to　enable　user　equipment　to　share　computing　resources　for　task　offloading.　Due　to　the　characteristics　of　the　computing　resource,　how　to　design　an　efficient　computation　incentive　mechanism　with　the　appropriate　task　offloading　and　resource　allocation　strategies　is　an　essential　issue.　In　this　manuscript,　we　proposed　an　intelligent　computation　offloading　mechanism　with　content　cache　in　mobile　edge　computing.　First,　we　provide　the　network　framework　for　computation　offloading　with　content　cache　in　mobile　edge　computing.　Then,　by　deriving　necessary　and　sufficient　conditions,　an　optimal　contract　is　designed　to　obtain　the　joint　task　offloading,　resource　allocation,　and　a　computation　strategy　with　an　intelligent　mechanism.　Simulation　results　demonstrate　the　efficiency　of　our　proposed　approach.
