The communication in IoT vs M2M is given below

You will need to learn Machine-to-machine (M2M) communications. With of help of figure, explain the functions of M2M communication. After learning M2M, discuss the difference between IoT and M2M in terms of:

a. Communication protocols

b. Machines in M2M vs Things in IoT

c. Hardware vs Software Emphasis

d. Data collection & Analysis

e. Applications
