The system method of M2M data communication between M2M devices is important to build M2M systems. With the progress of technologies of sensor, wireless-communications, virtualization, and the large-scale data processing, it is able to build advanced M2M systems. In order to use M2M data effectively, it is necessary to connect efficiently the three parts of the M2M sensor, gateway, and the server. This paper proposes a communication method between M2M devices based on SIP (Session Initiation Protocol) which is used for the communication between these parts. We applied the proposed method to a prototype of a watching system for a person living in a remote house, and evaluated the effectiveness of the system.
