Abstract：

The　large　scale　farmland　WSN　monitoring　has　the　characteristics　of　wide　area　and　energy　constraint.　Nodes　around　sink　node　undertake　lots　of　data　transfer　work,　so　these　nodes　have　the　problems　of　excessive　energy　consumption　and　some　of　them　are　inclined　to　early　death.　This　study　gives　an　improved　a　topology　control　algorithm　for　farmland　wireless　sensor　networks　based　on　Yao　Graph　topology　and　clustering　algorithm.　The　improved　algorithm　is　aimed　to　balance　the　nodes　energy　in　the　critical　region　and　prolong　the　network　lifetime　by　clustering　and　energy　regulatory　in　the　sink　node　communication　range.　The　simulation　results　shows　that　this　topology　control　algorithm　is　conductive　to　energy　balance　in　the　communication　key　areas-sink　node　communication　range　and　at　last　prolong　the　nodes　and　the　network　life　time.　©　2013　Asian　Network　for　Scientific　Information.
