For　the　limited　processing,　storage　and　energy　of　network　nodes　in　the　wireless　sensor　network　environment,　a　distributed　JPEG2000　coding　algorithm　based　on　mobile　agent　is　proposed.　Multiple　network　nodes　are　utilized　to　the　image　distributed　coding　and　mobile　Agent　mechanism　is　used　to　communicate　among　network　nodes.　The　energy　consumption　of　single　node　is　reduced　under　the　invariant　coding　performance　of　the　image,　thus　prevents　the　system　from　paralysis　caused　by　the　energy　depletion　of　single　node　and　prolongs　the　life　cycle　of　the　system.　Simulation　results　show　that　the　proposed　algorithm　is　better　communication　capability　of　network　nodes　while　the　quality　of　the　image　is　invariant　after　the　coding,　and　can　achieve　a　good　balance　of　the　network　energy　consumption　and　prolong　the　network　life　cycle　3　times　as　before.
