Download as PPTX, PDF2 likes3,232 views
The document compares Machine to Machine (M2M) communication with the Internet of Things (IoT), highlighting their differences in architecture, applications, and technologies. M2M focuses on device networking for data exchange with features such as low mobility and scheduled data transfer, while IoT emphasizes cloud storage and analytics. Key distinctions include communication protocols used and the types of hardware emphasized, with IoT leaning towards sensors and M2M towards embedded hardware.
M2M vs IoT: The Key Differences and Similarities
- 1. Internet of Things: M2M vs IoT Internet of Things tutorial Series Navjyotsinh Jadeja www.edtechnology.in
- 2. What is M2M Machine to machine (M2M) is a broad label that can be used to describe any technology that enables networked devices to exchange information and perform actions without the manual assistance of humans. Primarily M2M and IoT are similar in upper layer such as hardware, networking or devices. But they differ in system architecture, types of applications and underlying Technologies.
- 4. Various important feature of M2M M2M as discussed earlier refers to networking of various different types of devices for different applications such as data exchange, consumer services, etc. Keeping this very thing in mind below mentioned are the desired feature of M2M communication systems. 1. Time Telerancy: These systems should be designed keeping in mind that data transfer may take long time intervals. 2. Low Mobility: M2M unlike IOT devices are less Mobile. Hence, they have low mobility. 3. Scheduled: Data Sending/Receiving is pre-scheduled and happens with permission. 4. Low on power consumption: In order to efficiency of M2M application, it is a desired feature. 5. Packet Switched: M2M device should provide packet switching services.
- 5. Key Differences Domain IOT M2M Application IoT data can be stored over cloud hence can be used for analytics applications, remote diagnosis etc. M2M data is more preferably stored in point solutions and can be accessed locally. Hence used for on-premise solutions and local diagnosis. Protocols IoT & M2M differ in communication protocols and machines communicate. In IoT, they focus on protocols above network Layer e.g. HTTP, COAP,DDS etc. M2M uses proprietary and non ip based communication protocols e.g. Zigbee, Bluetooth, Modbus, IEEE 802.15.4 Hardware IoT is more focused on sensors and interfacing. Various components of IoT systems are sensors, internet and Networking Infrastructure. M2M is typically more emphasized on embedded Hardware. Machines vs Things The things in IoT refers to objects which are uniquely identifiable and can sense data In contrast, M2M have homogeneous machines within network.
