Clustering　routing　algorithm　is　widely　used　in　data　gathering　to　reduce　data　latency,　enhance　network　scalability,　and　prolong　the　network　lifetime.　When　sensor　nodes　transmit　their　data　to　the　sink　via　multi-hop　communication,　the　sensor　nodes　closer　to　the　sink　are　burdened　with　more　relay　traffic　and　die　early,　which　will　cause　network　partitions.　This　paper　presents　a　based　uneven　clustering　algorithm　to　solve　the　problem　of　energy　consumption　that　is　not　balanced.　Simulation　results　show　that　the　routing　algorithm　is　well　balanced　the　energy　consumption　of　the　network,　and　prolongs　the　network　lifetime.　©　2012　IEEE.
