Energy　consumption　by　wireless　sensor　nodes　has　always　been　a　key　issue　for　the　Internet　of　Things　(IoT)　due　to　the　characteristics　of　constrained　resources　in　the　sensor　nodes.　As　Compared　to　the　traditional　network　nodes,　it　is　easy　to　examine　those　traditional　network　nodes　and　sensor　nodes　that　co-exist　in　IoT　are　extremely　asymmetric　in　terms　of　network　bandwidth,　memory　space　and　processing　power.　On　the　other　hand,　most　current　protocols　that　we　use　are　designed　for　traditional　networks　without　considering　the　asymmetric　relationship　between　the　different　types　of　nodes.　In　the　paper,　we　propose　an　asymmetric　transport　protocol　that　respects　the　asymmetric　nature　of　the　communicating　nodes　through　reducing　energy　consumption　or　computation　of　the　resource-constrained　nodes　so　that　the　service　life　of　the　resource-constrained　nodes　can　be　prolonged.　We　will　also　verify　the　goal　of　the　protocol　design　to　show　that　the　protocol　design　can　decrease　the　energy　consumption　and　the　latency　of　data　packets　transmission　as　compared　to　the　transmission　control　protocol　(TCP).
