Abstract：In alusiontothe problem thatthe traditional low energyadaptiveclustering hierarchy （LEACH）protocol inradio frequencyenergy harvestingwirelessensor networks （RF-EHWSN）doesnotconsidertheremaining energyandcommunication distance of nodes intheclusterheadselection stage，resultingin highnodeenergyconsumptionandshorteningthenetwork life， as wellas theunbalancedenergyconsumptioncausedbysingle-hopdata transmision inthe steady-state phase，anenergyadaptiveclusteringandmulti-oproutingprotocolisproposed.Inthisprotocol，distanceandenergyfactorsareincoated duringthecluster formation phasetooptimize thecluster headselection process.Inthesteady-statephase，inter-clustermultihoproutingisemployed，whereclusterheadscanutilizeacostfunctiontoidentifyrelayroutingnodes，efectivelyreducing energyconsumptionduringdata transmision.Incomparison with the LEACHand LEACH-C protocols，the proposed protocol canextend the time until the first node death by 344.44% and1O5.13% respectively，and the timeuntil all O nodes die by 86.44% and 23.53% ，respectively. The network energy consumption is reduced by approximately 23.53% and 22.00% ，while the throughputisincreasedby212.90%and18.52%，respectively.Theexperimentalresultsdemonstratethattheproposedprotocol can significantly prolong network lifespan，balance energy consumption，and enhance network throughput.
