In　this　paper,　a　clustered　random　access　scheme　based　on　packet　aggregation　method　for　machine　type　communication　(MTC)　is　proposed,　for　which　MTC　devices　are　divided　into　clusters　according　to　their　locations.　The　neighboring　devices　are　assigned　to　the　same　cluster.　Devices　within　a　group　can　communicate　to　each　other　by　Device-to-Device　(D2D)　communication　methods.　The　newly　generated　packets　by　MTC　devices　are　transferred　to　the　machine　whose　number　of　packets　in　the　buffer　is　the　closest　to　the　given　threshold　in　the　group,　which　leads　to　shorter　waiting　time　of　packets　in　the　buffer.　Simulation　results　show　that,　the　proposed　scheme　can　significantly　decrease　collision　probability　and　average　delay　of　the　random　access　procedure　in　machine　type　communications.　©　2016　IEEE.
