Abstract
Machine-to-Machine (M2M) communication refers to technology that enables machines to be networked so data can be freely exchanged among these assets. It is a form of data communication that involves one or more entities that do not necessarily require human interaction or intervention in the process of communication. M2M communications emerge to autonomously operate to link interactions between Internet cyber world and physical systems. We present the technological scenario of M2M communications consisting of wireless infrastructure to cloud, and machine swarm of tremendous devices. Related technologies toward practical realization are explored to complete fundamental understanding and engineering knowledge of this new communication and networking technology front
