Introduction
- Communication between machine or devices with computing and communication facilities.
- Free of any human intervention.
- Similar to industrial supervisory control and data acquisition systems (SCADA).
- SCADA is designed for isolated systems using proprietary solutions, whereas MACHINE TO MACHINE (M2M) is designed for cross-platform integration.
M2M Overview
M2M Application
- Environmental monitoring
- Civil protection and public safety
- Supply Chain Management (SCM)
- Energy & utility distribution industry (smart grid)
- Intelligent Transport Systems (ITSs)
- Healthcare
- Automation of building
- Military Applications
- Agriculture
- Home networks
- Large number of nodes or devices.
- Low cost.
- Energy efficient.
- Small traffic per machine/device.
- Large quantity of collective data.
- M2M communication free from human intervention.
- Human intervention required for operational stability and sustainability.
M2M Node Types
Low-end Sensor Nodes
Low-end Sensor Nodes
- Cheap, and have low capabilities.
- Static, energy efficient and simple,
- Deployment has high density in order to increase network lifetime and survivability.
- Resource constrained , and no IP support.
- Basic functionalities such as, data aggregation, auto configuration. and power saving.
- Generally used for environment monitoring applications.
- More expensive than low-end sensor nodes.
- Nodes may have mobility.
- Fewer constraints with respect to complexity and energy efficiency.
- Additional functionalities such as localization, Quality of service (QoS) support, TCP/IP support, power control or traffic control, and intelligence.
- Typical application includes home networks, SCM, asset management, and industrial automation.
High-end Sensor Nodes
- Low density deployment
- Able to handle multimedia data (video) with QoS requirements.
- Mobility is essential.
- Example : smartphones.
- Generally applied to ITS and military or bio/medical applications.
