Wireless Communication

“Internet of Things”

“Internet of Things” Technology Architecture:

Nowadays, internet is being used extensively. There are many applications of internet which give ease & control. It has brought tremendous evolution in the society. Also there are many other revolutions in the cellular & consumer industries like PDA & cell phones. Likewise, the world of main stream commerce (like manufacturing, health, automobiles, production) Industries seeks a technology growth outside the traditional PC desktop to keep inventory of there products.

These needs come up with the identification technology called Auto-ID, which used to identify, automate, and reduce errors & increase the efficiency. These technologies include barcode, wireless sensors, smart card, voice recognition & nowadays RFID (Radio frequency identification).

Auto-ID labs, introduces the EPC network, which uses tiny RFID tags, which allow organizations to automatically do the tracking of the objects. Then it triggers the events to perform actions upon the objects using computers. This technology builds up the communication of nodes similar to internet technology widely known as "Internet of things." This technology has a remarkable impact on different commerce industries.

The technology:

The technology is identical to internet where everything is tagged & hence it can be identified uniquely. That’s why everyone can search & track the item. It is similar to node on internet today.

The core standards include:

• RFID tags & its associated data structure

• Tag readers with antenna & middleware software

• Communication protocol suite

• Object Naming Service ...

...embedded into tiny RFID tags & attached to the object. These tags track the object in a completely automated manner.

2) The RFID reader scans these tags through reader protocol. Which receives the items EPC code to the computer running middleware (e.g. savant)

3) Savant queries an object name services (ONS) database.

4) ONS maps EPC to a URL where object information which is stored using PML (physical markup language)

5) Hence data is been invoked, stored & managed.

Following are few applications of RFID EPC networks:

• Retailer items inventory

Other applications are like,

Monitoring & recording, real-time medical data

Manufacturing & Packaging Industry

Pharmaceuticals Industries & life sciences
