Abstract

Machine-to-Machine (M2M) communication has recently become a hot topic in 4G Standardization Committee, such as IEEE 802.16p and LTE-A. In an OFDMA cellular network embedded with a M2M system, we characterize system energy consumption (EC) and average delay for the M2M system and propose energy-efficient Machine Node (MN) access control schemes, jointly implementing MN grouping and coordinator selection, under a 2-hop transmission framework to minimize system EC with limited resource amount assigned by BS while satisfying the system delay requirement. In the simulation results, the tradeoff between EC and delay is investigated with respect to given resource amount, and the relationship between number of coordinators and total energy consumption is studied. Furthermore, the proposed schemes need relatively less coordinators to achieve very low EC, and can achieve near-optimal EC with any delay requirement.
