摘要: Position information is of vital importance in the various applications wireless sensor networks (WSNs). We analyze features localization methods considering both precision and energy consumption propose idea hybrid system (HLS). HLS composed coarse-grained (CGLS) fine-grained (FGLS). CGLS takes signal strength as reference for distance gets rough area a unknown node located. According to trade-off position consumption, FGLS charge location refinement that image localize node. The experiment results show proposed can achieve high low consumption.
