Wireless　Sensing　Networks　(WSNs)　comprised　of　significant　numbers　of　miniatures　and　reasonable　sensor　nodes,　which　sense　data　from　surrounding　and　forwarded　data　toward　the　base　station　(BS)　via　multi-hop　fashion　through　cluster　head　node　(CHN).　The　random　selection　of　CHN　in　WSNs　is　fully　based　on　the　nodes　residing　energy.　The　node　residing　energy　and　network　sustainability　is　hot　research　issues　of　the　day　in　WSNs.　There　are　many　deficiencies　in　less　energy　adaptive　clustering　hierarchy　(LEACH)　RP　due　to　the　rapid　energy　usage　of　ordinary　and　CHN　because　of　direct　communication　to　the　base　station.　The　rapid　draining　of　node　energy　produces　huge　numbers　of　hole　in　the　network　causing　retransmission　of　data　packet,　route　update　cost,　and　E2E　delay.　In　this　paper,　the　proposed　Delay　Sensitive　and　Energy　Efficient　(DSEE)　Routing　Protocol　(RP)　select　CHN　considering　distance　difference　and　amount　of　remaining　energy　of　neighboring　nodes.　In　this　proposed　approach,　data　fusion　technology　(DFT)　was　implemented　to　solve　the　problem　of　data　redundancy,　but　it　does　not　design　a　specific　data　fusion　algorithm.　At　last,　simulation　experiments　proved　the　superiority　of　the　improved　protocol　LEACH-DSEE　and　finally,　we　compare　this　improved　routing　protocol　with　existing　protocols　by　consideration　metrics　such　as　node　death　ratio,　data　packet　delivery　ration　and　node　energy　consumption.　©　2018　The　Science　and　Information　(SAI)　Organization　Limited.
