Abstract: In current scenario ZigBee wireless sensor network suffered from distribution of power and route cost for the selection of root tree node and communicating node. The power supply process of wireless sensor network is fixed type. The process of power used battery. Now most of authors followed the location based and heretical based protocol for minimization process of energy factor in wireless sensor network. In consequence of efficient energy and route cost minimization one is very famous routing protocol is shortcut tree routing protocol. In the process of improvement of ZTR protocol one protocol are available such are called as STR protocol. Basically STR protocol is a combination of two different routing protocols for the processing of energy saving mode and cost. The research gap between ZTR and STR is sharing of information for the selection of tree node process. During the cluster node selection more power is consumed. Now reduction of this power effect used reference node selection mode for the selection of tree head and data transmission for the communicating node.
