This　paper　is　concerned　with　dissipative　control　for　networked　stochastic　systems　with　an　event-triggered　transmission　mechanism.　Different　from　some　existing　results,　signals　from　a　physical　plant　are　sampled　non-uniformly.　In　order　to　save　precious　communication　resources,　a　data-packet　processor　is　introduced　to　choose　necessary　data-packets　based　on　a　flexible　event-triggered　condition.　By　establishing　an　integral　inequality　in　stochastic　setting,　which　is　regarded　as　a　counterpart　of　Wirtinger-based　inequality,　a　criterion　is　derived　such　that　the　resultant　closed-loop　system　is　mean-square　stable　and　dissipative.　This　criterion　is　then　used　to　calculate　suitable　event-triggered　controllers　in　terms　of　solutions　to　linear　matrix　inequalities.　An　air　vehicle　system　is　finally　taken　to　substantiate　the　validity　of　the　proposed　method.　(C)　2018　Elsevier　Inc.　All　rights　reserved.
