M2M meets D2D: Harnessing D2D interfaces for the aggregation of M2M data [PDF]
2017 IEEE International Conference on Communications (ICC), 2017 Direct device-to-device (D2D) communication presents as an effective technique to reduce the load at the base station (BS) while ensuring reliable localized communication. In this paper, we propose a large-scale M2M data Aggregation and Trunking (MAT) scheme, whereby the user equipments (UEs) aggregate M2M data from the nearby MTDs and trunk this data ...
