Abstract：

Solar-powered　nodes　employed　in　farmland　wireless　sensor　network　have　energy　advantages　but　at　the　same　time　have　the　problem　of　high　cost.　Wireless　sensor　network　employs　both　solar-powered　nodes　and　battery　powered　nodes　which　can　reduce　cost　and　prolong　network　lifetime.　This　paper　presents　an　algorithm　based　on　LEACH　to　study　the　clustering　process　of　farmland　environment　monitoring　sensor　network　which　contains　both　solar-powered　nodes　and　battery-powered　nodes.　This　algorithm　classifies　nodes　into　three　types　based　on　the　nodes　characteristics　first　and　the　nit　selects　cluster　nodes　based　on　the　comparison　of　the　number　of　cluster　head　nodes　and　the　solar　powered　nodes.　The　algorithm　in　this　paper　gives　priority　to　utilize　the　solar-powered　battery　by　two　elections　in　one　round.　Simulation　result　shows　that　this　algorithm　can　improve　the　utilization　of　solar　energy,　decrease　node　death　and　finally　prolong　the　network　lifecycle.　©　2010,　Bentham　Science　Publishers　B.V.　All　rights　reserved.
