emphasize theimportance ofutilizing location information intherouteselection. SinceSNsare Inthis paper, anenergy-efficient routing scheme for usually setupinafixed-wireless pattern orjust have sensornetworks basedon ultra-wideband (UWB) lowmobility, thelocation information ofsensors can technique isproposed andevaluated. Thisscheme be directly embeddedinor obtained by some makesuseofthepositioning capability ofUWB and positioning methods. We adopt a SN scenario that takes into account theenergy efficiency inthenetwork.applies UWB asphysical layer inorder toobtain its Bymodeling theproperty ofenergy consumption, itis positioning capability [5]. Although itisdifficult toget foundthat energy andquality-of-servi ce (QOS)issues anoptimal routing schemeforthewholenetwork, a aretightly related withroute selection. Accordingly, a kindofsub-optimal solution canbederived based on newrouting algorithm isderived tosearch forenergy- thelocation information. We start ourresearch witha efficient routesthatcansupport adequate QOS simple network topology toobtain therelationship requirements. Thesimulation results haveproved the between energy consumption androute selection. Then advantages ofthis routing scheme. anewrouting metric concerned withenergy canbe devised tofacilitate ourrouting method, whichisa
