2. Radio Frequency Identification ( RF ID ) Technology
Radio Frequency Identification ( RFID ) is a engineering which helps in tracking of the objects. It is really utile in stock list trailing. In this engineering there are three constituents viz. reader, a transceiver with decipherer and a transponder ( RF ticket ) .A This engineering works in concurrence with the IT substructure of any organisation. It improves the direction of any company. It is rather utile in instance of stock list direction.
RFID is one of several engineerings jointly known as Auto-ID processs. This engineering is chiefly used for placing objects automatically. RFID maps are now integrated in passports and will even happen their manner into wellness cards. In subsequent subdivisions working of RFID, different criterions used in engineering, upcoming engineerings are explained.
2.2 Functioning of RFID
RFID tickets enclose two parts chiefly. The first is an incorporate circuit for carrying up and treating the information, modulating and demodulating the signal of radio-frequency ( RF ) , and other dedicated maps. The subsequent is an aerial for conveying and having the signal. Three assortments of RFID tickets are bing fundamentally: inactive RFID ticket, that have no battery and necessitate an exterior beginning to motivate signal transmittal, active RFID ticket, that contain a battery and can air signals individually, and battery assisted passive ( BAP ) that necessitate an peripheral beginning to wake up although have notable higher frontward link capableness supplying a immense read scope. ( Radio frequence designation engineering, RF-ID, RFID, 20 Jan 2010 ]
The reader emits a wireless signal that activates the ticket and reads and writes informations to it. As merchandises are shipped, received or stored, the information ( encoded on a saloon codification like ticket ) can be read and received by the reader, which is attached to a computing machine. RFID has been integrated into the EPC ( Electronic Product Code ) planetary web and uses the EPC. The EPC is an sole figure that identifies a precise article in the supply concatenation. The EPC is stocked up on a RFID ticket, which joins a Si bit and a reader. Once the EPC is recovered from the ticket, this can be linked with dynamic informations such as the beginning of an point or the day of the month of its production. Greatly like the Global Trade Item Number ( GTIN ) or Vehicle Identification Number ( VIN ) , the EPC is the key which unlocks the power of the information systems that are portion of the EPC planetary Network. ( EPCglobal EPC Overview, 20 Jan 2010 )
Automatic designation ( car ID ) engineerings facilitate setup or computing machines in placing the points by agencies of automatic informations gaining control. The RFID is one such type of car ID engineering which uses wireless moving ridges to pull off, proctor, and place single objects as they move among physical locations. Even though there is an mixture of techniques for placing objects with RFID, most common method of usage is by hive awaying the consecutive figure which identifies the ware and its related informations. The RFID package and devices must be supported by a extremely developed package architecture which enables the distribution and aggregation of location based records in existent clip. In the coming subdivision, the description about the diverse types of tickets and readers is furnished. ( Microsoft RFID white paper, 19 Jan 2010 ) .
Tags and Readers
RFID tickets are infinitesimal devices holding a bit and an aerial which shops the informations for designation of objects. The tickets can be applied to instances, palettes, containers, or single points. In the thick of no line of sight requirement, the ticket transmits informations to the reader, and the reader transfers the inward wireless waves to a construction that can be read by a computing machine system. The RFID ticket can be classified chiefly as inactive ( powered by the signal strength emitted by the reader ) and active ( with a battery ) . Different characteristics of active and inactive tickets are mentioned below.
- Contain high power and battery demands, so these are heavy in weight and may besides be dearly-won.
- Can be read from distances of long scope of more than 100 pess.
These are ultimate for tracking the high value points over stretched scopes, such as in tracking the transportation containers which are in theodolite.
- These are less expensive, lighter, and smaller ( and hence extremely predominating ) than active tickets
- Can be applied in really immense figure to single points and can be reused.
A· Can be read merely from distances of short scope of about 5-10 pess.
As every engineering has the standardisation, this RFID besides has assorted regularities. There is no world-wide public organisation which supervises the frequences made usage for the RFID engineering. In theory, each state can put its single set of regulations for this. The nucleus organic structures regulating the allotment of frequence for RFID are listed as follows.
- United statess: FCC ( Federal Communications Commission )
- Europe: ERO, CEPT, ETSI, and national disposals, and
- Canada: CRTC ( Canadian Radio-television and Telecommunications Commission
( Radio-frequency designation, 18 Jan 2010 )
Low frequence ( LF: 140-148.5 and 125-134.2 kilohertz ) ( Low FID ) ticket and high frequence ( HF: 13.56 MHz ) ( High FID ) ticket may be used internationally barren of a mandate. Ultra high frequence ( UHF: 868-928 MHz ) ( UHFID or Ultra High FID ) ticket may non be used worldwide as there is no peculiar comprehensive norm prevailing. In the North America, UHF can be made usage of without a licence for the frequences 902-928 MHz ( above or below 13 MHz from the 915 MHz centre frequence ) , excluding which limitations are present for the transmittal power. Readers are needed to size up a channel before conveying this necessity if it has led to some restrictions on public presentation ; the declaration of it is a topic of present survey. North American UHF criterions are non time-honoured in France as it mingles with the predominating military sets. For China, India, and Japan, there are no established regulations and ordinances framed for the usage of UHF frequences. Every contraption for UHF in these states requires a site licence, that needs to be applied at the place governments, and it can be rescinded. In the states of New Zealand and Australia, the frequence 918-926 MHz is non licensed but bounds subsist for the transmittal power.
The above frequences are branded as Industrial Scientific and Medical sets ( ISM bands ) . Homecoming signal of the ticket can yet take to interference for new or bing wireless users. A few criterions that are laid down refering RFID engineering are as follows:
- ISO/IEC 14443: This criterion is an recognized HF ( 13.56 MHz ) criterion for High FID ‘s which is extremely used as the foundation of RFID enabled passports under the act ICAO 9303.
- ISO 15693: This is besides an established HF ( 13.56 MHz ) norm for High FID ‘s commonly used for recognition cards and non contact smart payment.
- ASTM D7434, customary trial method for measuring the running of inactive Radio Frequency Identification ( RFID ) transponders on unitized or palletized tonss.
- ASTM D7435, customary trial method for measuring the running of inactive Radio Frequency Identification ( RFID ) transponders loaded containers.
- ASTM D7580 customary trial method for Rotary Stretch Wrapper Method in measuring the readability of inactive RFID transponders on unitized or homogeneous palletized tonss.
- EPC planetary, this is the evenness model that is the bulk probably to undergo International Standardization harmonizing to ISO regulations as with all sound ordinances across the universe, until shacking with unequal range, as air-traffic ordinances imposts ordinances, and others.
- ISO 14223/1 – Radio frequence designation of the animals/human existences, and for advanced transponders in air interface.
- ISO/IEC 18000: Information engineering – Item direction utilizing Radio frequence designation.
- ISO 18185: This is the concern criterion for e-seals or electronic seals in tracking lading vass via the usage of frequences 433 MHz and 2.4 GHz.
There are different alternate RFID engineerings are upcoming based on the different type of reader like optical reader, reader that is installed on the devices like Mobile. In the undermentioned subdivision a brief note is mentioned about the optical and nomadic RFID is explained. ( Radio frequence designation engineering, RF-ID, RFID, 16 Jan 2010 )
2.5 Optical RFID
Optical RFID ( OPID ) is a replacement to RFID which is based on the engineering of optical readers. Applications for optical RFID ticket may be conveying into being in the approaching scenarios of supply concatenation direction. The first advantage in contrast to conventional RFID ticket is their little monetary value and the typically employed offline pre collection of information to the category degree.
Not like most other RFID french friess, ( that make usage of wireless frequences of 0.140-0.1485, 0.125-0.1342, 868-928, and 13.56 MHz ) , optical RFID operate in the electromagnetic spectrum affecting the frequences of 333 THz ( 3.33A-1014 Hz, 900 nanometer ) , 380 THz ( 788 nanometer ) and 750 THz ( 400 nanometer ) . The ticket information is transmitted to the reader by repeating the read petition. Balls of the incoming signal are filtered out by the ticket in a well defined form as it is reverted to the reader. At the reader ‘s side, the ticket information can be deduced by size uping the paradigm used for filtrating. As an option to the contemplation manner, active circuits may be used, reinstating the gauche RFID aerial with IR-LEDs on the ICs and photovoltaic constituents. Refering to privateness, optical RFID affords much extra security against development than RFID based on widespread electromagnetic moving ridges. This is chiefly for the ground that line-of-sight is obligatory for malevolent read out. These assaults can effortlessly be barred with small cost optical RFID sight blockers.
2.6 Mobile RFID
Mobile RFID ( M-RFID ) can be described as services which provide informations refering to objects equipped with an RFID ticket over the telecommunication web. A reader is installed in a nomadic device like a PDA or nomadic phone. This complete novel scheme is different from modern-day executions of ordinary RFID. Soon the readers are nomadic and tickets can be preset, as an option to the other manner around. The M-RFID has a figure of major and evident advantages over RFID. There are no wires necessary to the fixed readers to any farther extent and legion nomadic readers are sufficient to cover a whole country, as a replacement of utilizing tonss of fixed readers.
The cardinal constituents are at all times a reader and a ticket. Typically the reader is in some manner connected to a back terminal database which shops farther information on the article to which the ticket is fixed to. Connection to the database is largely made by the piece of equipment that holds the reader and which is capable to link to an cyberspace or local ( radio ) web. A assortment of participants like the EPC ( Electronic Product Code ) planetary, Near Field Communication Forum ( NFC ) , and European Telecommunications Standards Institute ( ETSI ) are involved in developing M-RFID solutions. Main focal point is laid on supplying support to the supply concatenation direction. However this contraption has besides instituted its manner in nomadic commercialism. A client in the supermarket can scan the electronic merchandise codification with the aid of the ticket and connect by agencies of the cyberspace to acquire more information of the merchandise desired. “ Information engineering – Automatic Designation and Data Capture Technique – Air Interface specification for Mobile RFID inquisitor ” is the first ISO/IEC 29143 criterion to be developed for Mobile RFID.

3. Parallel Calculating
All the computer science in the olden yearss is used happen in consecutive mode. Software and the applications developed are written in consecutive calculation. Features and events that occur often in the consecutive computer science are mentioned below.
- A individual computing machine has a individual CPU ( Central Processing Unit )
- A applications is written in series of instructions
- All the instructions executed serially and executing of multiple instructions is non possible.
Now a twenty-four hours ‘s applications are turning bigger and bigger. Execution of these on the individual consecutive computing machine takes batch of clip. This in bend gives hapless public presentation to the user. In order to give the user high public presentation and to make calculation fast parallel computer science is required.A
- Programme runs on multiple CPUs
- Application can be broken into independent parts those can be solved at the same time.
- Each independent set broken into the separate set of instructions
- All the instructions related to each independent portion executes individually on separate CPU.
Calculating resources may include multiple CPUs or computing machines connected through web or the combination of both.
Computer architecture can be classified on the footing of two theories
1. Von Neumann Architecture. It is based on the theory proposed by the Magyar mathematician John von Neumann. In early phases all computing machine system are followed this theory to plan the computing machines. Harmonizing to this theory it has memory, control unit, Arithmetic logic unit, I/O devices. Single memory is used to hive away the programme and informations [ 1 ] .
2. Flynn ‘s taxonomy. Parallel computing machines can be classified chiefly on the footing of Flynn ‘s taxonomy. Harmonizing to this theory of import constituents direction and informations are the determinant factors for the categorization. On the footing of this there are four classs.
- Single direction Single information
- Single direction Multiple informations
- Multiple direction Single information
- Multiple direction Multiple information. ( Introduction to Parallel Computing, 15 Jan 2010 )
3.2 Memory Architecture
There are different memory architectures that can be followed in the parallel computing machine engineering. Shared memory is one of those architectures. In shared memory architecture all the processors present in the system has to entree the individual memory. In this besides there are two categorization Uniform and Non unvarying memory entree architecture. In unvarying memory entree architecture all the processor will hold the same entree clip. Non unvarying memory architecture has different entree clip for different processors. Main advantage of the memory architecture is data sharing between the undertakings will be really fast. It has major disadvantage besides that there will non be any scalability between CPUs and memory. Unlike in the shared memory, distributed memory architecture each and every processor has separate memory. But this system requires common computing machine architecture. Memory reference for the each processor will be different and there is construct of the planetary reference infinite. Main advantage of this architecture is memory scalable. There will non be any memory coherency in this architecture. Disadvantage is developer is responsible for inside informations associated with informations and communicating. The other architecture for the parallel computer science is intercrossed memory architecture. It implements constructs of both shared and distributed. This is one of the most widely used architecture in this type of calculating.
3.3 Programming Models
There are several types of programming theoretical accounts available for parallel computer science. Some of them are mentioned below.
- Data Parallel
- Shared Memory
- Message Passing
- Togss and
