Abstract：

Radio　frequency　identification　(RFID)　is　a　promising　technology　for　ubiquitous　computing.　To　improve　its　function　and　capability,　it　is　necessary　to　integrate　RFID　with　Wireless　Sensor　Networks　(WSNs).　Although　organized　well,　the　reader　collision　problem　is　still　one　of　the　critical　problems　in　these　networks.　In　this　letter,　we　propose　a　Multichannel　Reader　Collision　Avoidance　(MRCA)　mechanism　for　the　cluster　constructed　RFID-Sensor　integrated　networks.　In　this　mechanism,　cluster　headers　collect　channel　information　of　nodes　and　arrange　nodes＇　reading　time　and　transmission　energy,　while　gateway　schedules　clusters＇　reading　sequence　in　the　same　way.　By　using　this　mechanism,　the　system　throughput　and　efficiency　can　be　highly　increased　according　to　the　simulation.　©　2018　Computer　Society　of　the　Republic　of　China.　All　rights　reserved.
