Machine-to-machine (M2M) communications
are expected to provide ubiquitous connectivity
between machines without the need of human
intervention. To support such a large number of
autonomous devices, the M2M system architec-ture needs to be extremely power and spectrally
efficient. This article thus briefly reviews the fea-tures of M2M services in the third generation
(3G) long-term evolution and its advancement
(LTE-Advanced) networks. Architectural
enhancements are then presented for supporting
M2M services in LTE-Advanced cellular net-works. To increase spectral efficiency, the same
spectrum is expected to be utilized for human-to-human (H2H) communications as well as
M2M communications. We therefore present
various radio resource allocation schemes and
quantify their utility in LTE-Advanced cellular
networks. System-level simulation results are
provided to validate the performance effective-ness of M2M communications in LTE-Advanced
cellular networks.
