Abstract:

In Machine-to-Machine (M2M) networks, an energy
efficient scalable medium access control (MAC) is crucial for
serving massive battery-driven machine-type devices. In this
paper, we investigate the energy efficient MAC design to minimize
battery power consumption in cellular-based M2M communications.

We present an energy efficient MAC protocol that not
only adapts contention and reservation-based protocols for M2M
communications in cellular networks, but also benefits from
partial clustering to handle the massive access problem. Then we
investigate the energy efficiency and access capacity of contentionbased
protocols and present an energy efficient contention-based
protocol for intra-cluster communication of the proposed MAC,
which results in huge power saving. The simulation results show
that the proposed MAC protocol outperforms the others in energy
saving without sacrificing much delay or throughput. Also, the
lifetimes of both individual nodes and the whole M2M network
are significantly extended.
