1 B] Differentiate between IoT and M2M.
M2M or the machine-to-machine paradigm refers to communications and interactions between
various machines and devices. These interactions can be enabled through a cloud computing
infrastructure, a server, or simply a local network hub. M2M collects data from machinery and
sensors, while also enabling device management and device interaction. Telecommunication
services providers introduced the term M2M, and technically emphasized on machine
interactions via one or more communication networks (e.g., 3G, 4G, 5G, satellite, public
networks).
M2M is part of the IoT and is considered as one of its sub-domains, as shown in Figure 7.
M2M standards occupy a core place in the IoT landscape. However, in terms of operational and
functional scope, IoT is vaster than M2M and comprises a broader range of interactions such as
the interactions between devices/things, things, and people, things and applications, and people
with applications; M2M enables the amalgamation of workflows comprising such interactions
within IoT. Internet connectivity is central to the IoT theme but is not necessarily focused on
the use of telecom networks.
